Frequently Asked Questions
What is Tess AI's satisfaction guarantee policy?
At Tess AI, customer satisfaction is our priority. With a community of over 1 million users and partnerships with global AI leaders, we guarantee our platform can help you transform your professional routine. We offer a 7-day satisfaction guarantee: if you're not completely satisfied with your membership, we'll fully refund your payment. (For all plans limited to first subscription)
Why should I pay for credits when I can use ChatGPT for free?
Free ChatGPT or Claude limits you to a single model with slow responses and no advanced features. At TESS AI, for an affordable membership (see pricing table above - cheaper than ChatGPT's paid plans), you get access to 250+ AI models, custom agents, unlimited users, and full control over which tool to use. But the real question is: we're in the biggest technological revolution in history, reaching all countries simultaneously for the first time, accessible from the start. For the price of a pizza per month, you can use AI's full potential for your personal and professional life. If you choose the free limited version instead of investing in this, you're saying you don't prioritize your career and future. Priority is everything - and people who don't invest in AI clearly don't prioritize professional impact in their own lives.
I'm not tech-savvy. I won't be able to use this, will I?
TESS AI was built exactly with you in mind. Our interface is as simple as using WhatsApp - you type what you need and the AI responds. You don't need to understand 'tokens', 'parameters' or 'embeddings' (unless you want to dive deeper). We include the AI University with 40 lessons from basic to advanced, guiding you step by step. The system automatically suggests which model to use for each task. You can start with simple commands like 'summarize this document' or 'create an image of a dog' and evolve at your own pace. We have users up to 80 years old using it daily - from teenagers doing homework (with parents monitoring via Parental Control) to retirees creating social media content. The technology is complex behind the scenes, but we use it to make your life simpler. If you know how to use a phone, you know how to use TESS AI.
What's included in the Tess AI membership?
Your annual membership (see pricing table above for details) includes initial credits upfront, plus access to the complete Tess AI ecosystem: 250+ authentic AI models from OpenAI, Anthropic, Google, and more; Smart/Max Memory to save up to 70% on input tokens; Memory Collections for personalized AI responses; Advanced AI Tools including the AI Computer, document editing, image/video generation/editing, avatars, audio, and music; Agentic Mode with cross-model interactivity; unlimited user sharing with shared credit wallets; Parental Control (first AI platform designed for families); full API access; AI University course (40 lessons from basic to advanced); and all future improvements at no additional cost. This is a complete AI ecosystem, not just a chat interface with hidden restrictions.
Is my data used for training AI models?
At Tess AI, the privacy and security of our users' data are fundamental. The data you provide is not used for training artificial intelligence models. Our priority is to keep your information confidential and secure, in compliance with all applicable data protection regulations and standards. For more information about our privacy policy, please contact us.
How does the shared credit wallet work?
Tess AI pioneered the world's first shared wallet system for AI. After purchasing your annual membership, invite unlimited users - family members, colleagues, or study partners. Each person gets their own private account with individual usage tracking, but everyone draws from the same shared credit pool. This is perfect for families using Parental Control, businesses managing team AI usage, or students collaborating on projects. Credits are flexible: use them for any model, any feature, any time. Purchase credits once, and everyone benefits. While unlimited platforms charge per person monthly with costs multiplying by team size, your team shares transparent, real-usage costs. No hidden limits, no per-user fees, no surprises.
I think I'll use it sparingly, just occasionally. Is the subscription really worth it?
That's the beauty of TESS AI's model - you DON'T need to use it every day to make it worthwhile. With our plans (see pricing table above), you get full platform access and credits that refill regularly. Even if you use it just once a week for specific tasks - summarizing an important document, creating a presentation, generating images for a project, researching something complex, transcribing a meeting - it's already worth it. And you'll NEVER miss out on any AI market innovations: when a revolutionary new model launches, you can test it immediately, always with access to original models in their maximum configuration (Max Mode). Even better: you can share with family or colleagues through unlimited users. So even if YOU use it sparingly, your spouse can use it for work, your kids for studies, and everyone shares the same credits. It's literally impossible to 'waste' the subscription when multiple people can take advantage. A single use that saves you 2-3 hours already paid for the entire month.
You say you have 250+ models, but I only know ChatGPT. Are the others any good?
That's the trap of using a single tool. ChatGPT is excellent at conversation, but Claude Opus excels at code analysis. Gemini better understands long contexts. Each model has its unbeatable specialty. At TESS, models work in collaboration, creating super models with record-breaking performance. That's why no single AI beats all of them together. Flux Pro generates photorealistic images, VEO 3 creates professional videos, Minimax composes music, ElevenLabs creates voices. At TESS AI you choose the right tool for each job. Different tools, superior results. All in a unified interface, without needing to pay for 10 different accounts.
How do I know you won't drastically increase prices after I get used to it?
Transparency is TESS AI's DNA. Our business model is based on a small margin (average 20%) over the actual API cost from AI providers. When OpenAI, Anthropic or Google reduce prices (as they constantly do), we automatically pass it on. We have no incentive to inflate costs because you see how much each query costs in our account history. Additionally, your annual subscription guarantees access to features for the contracted period. Unlike 'unlimited' platforms that can silently block your usage, our contract is clear: you pay for what you use, see how much you're using, and can adjust in real time. We have over 2 million users precisely because we build trust through radical transparency, not through pricing tricks. Our reputation depends on you recommending TESS - not on trapping you with abusive increases.
What if I accidentally spend all my credits in one day? Will I be left with nothing?
That's a valid concern and that's why we built multiple protections. First, you see the estimated cost of most actions BEFORE executing - no surprises. Second, the system shows your balance in real time at the top of the screen. Third, you can buy more recurring credit without drastically changing your profile, unlike ChatGPT where users who hit the limit have to migrate to a plan 10x more expensive. But the real protection is transparency: you always know where you are and how much you're spending.
My company uses Microsoft/Google Workspace. Why not just use their AIs?
AIs integrated into Microsoft 365 and Google Workspace are convenient, but severely limited. You're stuck with the models they chose (usually old or limited versions to control costs), with no option to test competitors that might be better for your specific task. At TESS AI, you access the latest models from ALL companies simultaneously - and can even make them work together through Cross-Model Interactivity. More importantly: you can embed custom agents on your website or app through External Agents, create custom APIs, sell AI solutions to clients, and use our Memory Collections system to train business-specific responses. Companies using TESS alongside their workspace report significantly higher efficiency because they choose the best tool for each situation, not the one that came 'free' (which is actually embedded in the license price).
What if TESS AI goes bankrupt or shuts down? Will I lose everything I invested?
We understand this concern, especially with so many startups closing. But consider the facts: we're OpenAI's largest partner in Latin America, with official partnerships with Anthropic, Google and other AI giants. We have over 2 million active users. Our infrastructure runs on Google Cloud Platform with enterprise redundancy and scalability. The business model is sustainable - we don't depend on investors burning money, we charge a fair margin on actual usage. But still, your investment is affordable - less than a lunch for two per month. It's not a lifetime commitment or significant financial risk. And unlike proprietary software, the AI you learn to use (prompts, techniques, workflows) is transferable to any platform. The knowledge stays with you. That said, our month-over-month growth and strategic partnerships indicate we'll be here for a long time.
You talk about 'Parental Control' and 'family sharing'. Won't my kids use AI to cheat on tests?
That's a legitimate concern for responsible parents - and exactly why TESS AI was the first AI platform designed for families with robust Parental Control. You can: see your children's entire conversation history with the AI. But beyond controlling, you can educate. Use TESS to teach ethical AI use - just as we teach children to use the internet responsibly, not by banning it completely. Configure AI agents to not give ready-made homework answers, but rather teach reasoning. Our AI University courses include lessons on ethics and responsible use. The reality is: your children will encounter AI anyway. The question is: do you prefer it to be on a platform where you can supervise and educate, or hidden in tools you don't even know about?
I've seen so many empty AI promises that will 'revolutionize everything'. What makes you different?
Healthy skepticism - we appreciate that. The difference lies in three concrete and verifiable pillars. FIRST: Radical transparency. Log into the dashboard right now and see the real cost of each query, the exact models you're using, consumption in real time. No 'unlimited' platform shows you this because they hide what they're really doing. SECOND: Revolutionary collaboration. At TESS, multiple models work together through Cross-Model Interactivity - GPT-5 collaborates with Claude, which collaborates with VEO 3, creating super models with record-breaking performance that no isolated AI can achieve. And this extends to you: unlimited users sharing the same wallet, family working together, teams collaborating on projects, parents monitoring children with Parental Control. We're the only platform where both models and people work in true collaboration. THIRD: Features nobody else offers because they're advanced and depend on transparency and collaboration: TESS Computer (complete virtual machine), agentic mode, External Agents to embed on your site, complete API.
How much can I generate with each AI model?
Excellent question! The exact amount varies by model, as each has different costs. That's why we created an interactive calculator in the 'Find Your AI Model' section above on this page - there you can simulate exactly how many messages, images, videos or audios you can generate with your credits on each specific model. The pricing table above shows you detailed information about what you get with each plan. And remember: you can and should buy as many additional credits as you want, depending on your usage (without needing to migrate to plans 10x more expensive like what happens with ChatGPT).
What if my credits run out in the middle of the month?
This will NEVER happen! In all TESS AI plans, you receive credits with automatic daily refill (check the pricing table above for specific amounts per plan). This means every day you wake up with new credits in your account, ensuring you never get stuck in the middle of an important project. Even if you use the platform intensively and consume your credits, the next day you already have more credits available. It's our way of ensuring AI is always accessible when you need it. And if you still need more for a specific project, you can purchase one-time credits at any time - these extra credits don't expire for 12 months. Zero stress, continuous use guaranteed.
Why are my credits divided into daily refill and monthly refill?
This smart division was created precisely to eliminate the stress of 'running out of credits' and turn AI into part of your daily routine. The daily refill ensures you always have credits available for recurring use - those day-to-day tasks like answering emails, doing research, creating content, summarizing documents. It's an incentive for you to use AI consistently and truly transform your productivity, not just occasionally. The monthly refill gives you a larger volume for more ambitious projects - creating multiple presentations, generating videos, doing deep research, developing complete campaigns. This model encourages both habitual use (which is where AI really changes your life) and freedom for larger demands. And if you need even more flexibility, you can always buy one-time credits that expire in 12 months, with no pressure for immediate use. It's the best of both worlds: daily predictability + flexibility for large demands.
With unlimited platforms, I just pay one price and use everything. Why should I consider Tess AI's membership model?
That \one
Unlimited platforms let me use AI without worrying about costs. Isn't pay-per-use more stressful?
That \worry-free\ promise is an illusion. Those platforms have hidden \fair
My unlimited platform advertises access to GPT-5 and Claude. How can Tess AI guarantee I'm using real models?
This is where unlimited platforms deceive users most. When they say \GPT-5,\ they might be running GPT-5 nano (25x cheaper) or mini behind the scenes. Since they're closed systems without API access, you can't verify anything. At Tess AI, we're official partners with OpenAI, Anthropic, Google, and other leading AI companies. Our pay-per-use model means we have zero incentive to swap models - we charge based on actual API costs. You can verify through our API responses, model metadata, and consistent performance. When you pay for GPT-5, you get GPT-5. When you pay for Claude Opus, you get Claude Opus. Our business model depends on your trust, not on deceiving you with cheaper alternatives.
Why pay for membership plus credits? Isn't that just paying twice?
It seems counterintuitive until you understand what each payment unlocks. The membership (see pricing table above for details) gives you access to the entire Tess AI ecosystem: 250+ AI models, Smart/Max Memory (save up to 70% on input tokens), Memory Collections, Advanced AI Tools, Agentic Mode, Cross-Model Interactivity, AI University course, Parental Control, unlimited users, and the world's first shared wallet system. Unlimited platforms charge per user monthly for access to restricted features and fake \unlimited\ promises. At Tess AI, your membership lets unlimited people share the platform and credits. For families, teams, or study groups, you're paying once for everyone vs per-person monthly fees. Plus, your credits go significantly further than official plans because we use direct API access.
I can't share my unlimited account with family. But that's normal, right? Each person needs their own account.
That's what unlimited platforms want you to think - because they profit from charging every single user separately. At Tess AI, we pioneered the world's first shared wallet system for AI. Invite unlimited users - family members, colleagues, students - each with their own private account and usage tracking, but sharing the same credit wallet. This is perfect for families (parents monitoring kids' AI usage with Parental Control), businesses (teams collaborating with shared resources), or study groups (students pooling resources). While unlimited platforms charge per person with costs multiplying by family size, at Tess AI your family shares one membership + credits. We built this because we believe AI should bring people together, not force everyone to pay separately.
Why don't unlimited platforms offer API access? I thought that was standard.
This is the biggest red flag in the industry. API access would expose their true limitations because users could automate usage, integrate into workflows, and quickly hit those hidden caps. Most unlimited platforms deliberately avoid APIs because it would prove they can't deliver unlimited access - automated systems would consume their entire margin in days. At Tess AI, we proudly offer full API access because we're transparent about our model. We charge on average 20% + API pricing, and you can integrate AI into any workflow without restrictions. Our shared wallet system even works through API, allowing teams to build applications that draw from the same credit pool. No hidden limits, no account suspensions, no surprises.
My unlimited platform says I have full access to all premium models. Is that really impossible?
Let's do the math: Premium AI models like GPT-5 and Claude Opus have significant API costs, and advanced video generation can be expensive per video. A single power user could easily consume substantial API costs per month. How can unlimited platforms afford this with their monthly fees? They can't. They stay profitable by switching you to cheaper model variants (which can be 25x cheaper than premium versions!), implementing hidden caps, reducing context windows, or blocking accounts for \fair
I noticed conversations on unlimited platforms sometimes forget context. Is that normal?
No, and it reveals one of their hidden cost-cutting measures. While official models offer context windows of 128K-200K tokens, many unlimited platforms silently reduce this to 32K or 16K behind the scenes to save costs. Why? Context window size directly impacts API costs - larger context means more tokens processed per request. That's why conversations suddenly \forget\ things you said earlier. At Tess AI, since you pay for actual usage, we have no reason to limit context. You get the full capacity of each model as designed by its creators. Your membership (see pricing table above) gives access to full-context models, and with our on average 20% + API pricing model, you're paying for authentic performance, not crippled versions.
My unlimited platform doesn't have deep research or advanced web search. I assumed those features weren't available yet.
They're available - just not on unlimited platforms because they're too expensive to offer freely. A single deep research task consumes 200K-500K tokens with multiple searches, cross-referencing, analysis, and synthesis. Quality web search requires 3-5 queries per search to cross-validate information. If you ran just a few deep research tasks on unlimited platforms, you'd exceed their entire revenue in API costs. That's why they either don't offer these features, severely limit quality (using only 1 query), or implement daily caps. At Tess AI, your membership unlocks all advanced features: deep research, multi-query web search, browser use, agentic mode, and more. You pay transparently for what you use, and with shared wallets, teams can pool resources for intensive research projects.
I need bulk generation and agentic mode for work. Can I really use these freely on Tess AI?
Yes, absolutely - and this is where unlimited platforms fail businesses completely. True agentic mode requires multiple AI calls, tool usage, and iterative reasoning, consuming 10-50x more tokens than simple chat. Bulk generation lets you create multiple outputs simultaneously. If unlimited platforms offered these unrestricted, they'd go bankrupt. That's why they either don't offer them, severely limit usage, or suspend accounts for \abuse\ when you use what you paid for. At Tess AI, your membership unlocks all advanced features: agentic capabilities, bulk generation, memory collections, the AI Computer, and cross-model interactivity. You pay transparently (on average 20% + API pricing) for what you actually use, with no hidden limits or account suspensions. Perfect for businesses that need real AI power.
Can I use expensive models like VEO 3 for video generation or Flux Pro for images?
Yes, with full transparency. Video generation models like VEO 3, premium image models like Flux Pro, and advanced voice models are extremely expensive - single generations can have significant API fees. Unlimited platforms with their fixed monthly fees simply cannot offer these. They either exclude them entirely, offer only cheap alternatives, or implement per-use charges that defeat the \unlimited\ promise. At Tess AI, your membership gives access to all cutting-edge models: VEO 3, Flux Pro, Suno for music, ElevenLabs for voice, and more. We charge on average 20% + API pricing, so you see exactly what each generation costs. With shared wallets, teams can pool credits for expensive productions. Real models, real capabilities, real transparency.
If unlimited AI is impossible, why do so many platforms offer it?
Because it's brilliant marketing that exploits lack of understanding about AI economics. By the time users realize the service is throttled, using cheaper models, or missing key features, they've already paid. Many won't notice they're using GPT-5 nano instead of GPT-5, or will blame themselves when features stop working. These platforms count on most users barely using the service, subsidizing active users with inactive ones. But for power users, families, businesses, and students who actually need reliable AI, these platforms fail spectacularly. At Tess AI, we built a different model: transparent membership + credits with on average 20% + API pricing, shared wallets for unlimited users, access to 250+ real models, and exclusive features you won't find anywhere else. We grow when you succeed, not when we deceive you.
Why choose TESS AI over free ChatGPT or Claude?
Free ChatGPT and Claude severely limit you to weaker models, restricted features, and no advanced capabilities. But here's what they don't tell you: they're using your conversations to train their AI models. Your data, ideas, and intellectual property become their training material. At TESS AI, your data is NEVER used for training - we guarantee complete privacy. Plus, for an affordable annual membership (see pricing table above), you get access to 250+ premium models including GPT-5, Claude Opus, Gemini Pro, plus exclusive features like Smart Memory, Parental Control, and collaborative accounts. While free platforms extract value from YOUR data, TESS gives you transparent access to cutting-edge AI while protecting your privacy. You're not the product - you're the customer.
What about 'free' AI models like DeepSeek? Why pay for TESS?
Those 'free' models aren't really free - you pay with something far more valuable: your data. DeepSeek, like free ChatGPT, explicitly uses all your conversations to train and improve their models. Every business idea, creative project, personal information, or proprietary strategy you share becomes their intellectual property. The real cost? Your privacy, competitive advantage, and data security. At TESS AI, we have a different philosophy: you pay transparently (on average 20% + API pricing), and in return, we NEVER use your data for training. Your conversations, documents, and ideas remain yours. Plus, you get access to 250+ premium models, many of which outperform DeepSeek significantly. Would you give away your business strategy to save a few dollars? That's what 'free' AI really costs.
ChatGPT costs 0/month. How is upgrading at TESS AI different?
This is where TESS AI's model shines. ChatGPT's upgrade path is brutal: their basic plan gets you basic access, but if you need more (Pro tier), you suddenly jump to a 10x price increase! Hit the limits on the basic plan? You're stuck or forced into an extremely expensive upgrade. At TESS AI, upgrading is smooth and flexible. Start with an affordable membership and buy credits as you need them. Need more capacity? Just purchase additional credits - no forced tier jumps. Your usage scales naturally with your needs. Our plans (check the pricing table above) all grow gradually. Compare that to ChatGPT's 10x price jump. We believe AI access should scale reasonably with your usage, not force you into unaffordable tiers or leave you severely limited.
Why does TESS have models ChatGPT doesn't offer?
Here's a perfect example: While the world was already experiencing revolutionary AI models like Kling, Minimax Hailuo, Leonardo AI, and Flux for images and videos, ChatGPT was still stuck on DALL-E for almost a year. Their paying customers were locked out of the biggest AI innovations in image and video generation during that entire period. At TESS AI, this never happens. We integrate cutting-edge models as they launch: VEO 3 for video, Flux Pro for photorealistic images, Minimax for music, ElevenLabs for voice, and dozens more. When you're locked into ChatGPT or Claude, you miss innovations for months or even years. At TESS, you get immediate access to every major AI advancement worldwide - 250+ models from multiple companies, not just one. Your AI capabilities should never be limited by which company you subscribed to. The future of AI is multi-model, and TESS is the only platform delivering that today.
You claim 250+ models perform better than isolated models. How is that possible?
It's simple: collaboration beats isolation. At TESS AI, models work together through our Cross-Model Interactivity system. Here's a real example: Start with GPT-5 to analyze a problem, then ask Claude Opus to refine the code, then use Gemini Pro for long-context research, and finally generate visuals with Flux Pro - all in one unified workflow. Each model contributes its unique strength. No single model is best at everything. ChatGPT excels at conversation, but Claude is superior for code analysis. Gemini handles longer contexts. Perplexity specializes in research. At TESS, you orchestrate them together, creating super-powered AI solutions that no isolated platform can match. Isolated models give you one perspective. TESS gives you 250+ expert perspectives collaborating on your task. That's why our users consistently report better results - they're not limited to one company's strengths and weaknesses. The future of AI is collaborative, and TESS is the only platform built for it.
What makes TESS's collaborative accounts different from other platforms?
TESS AI pioneered the world's first truly collaborative AI platform. Think about it: in the future, will every family member need their own ChatGPT subscription? For larger families, the costs multiply dramatically. That's unsustainable. At TESS, we built shared wallets where unlimited users collaborate under one membership: parents can monitor children's AI usage with Parental Control, teams can manage projects together, students can pool resources for group work, and everyone shares transparent credit pools. Each person gets their own private account with individual usage tracking, but the family/team shares costs. The future of AI isn't isolation - it's collaboration. Just as families share Netflix accounts, they should share AI access. TESS is the first and only platform designed for this reality. While ChatGPT, Claude, and others force everyone to pay separately per person, TESS's model lets unlimited users collaborate and share. That's the future, and it's only available at TESS today.
Do ChatGPT and Claude have hidden usage limits?
Yes, and this is one of the industry's dirtiest secrets. Both ChatGPT and Claude have usage caps that aren't clearly disclosed upfront - they're buried in documentation or terms of service. You only discover you've hit the limit when you're in the middle of an important task and suddenly get blocked or throttled. Their paid plans have message limits that vary by load. They call it 'fair use policy' but won't tell you the exact limits. At TESS AI, we believe opacity creates stress and uncertainty. Every query shows you the exact cost in real-time. Your account dashboard displays remaining credits, usage history, and projected costs. No surprises, no hidden caps, no sudden blocks. You see exactly what you're spending and can plan accordingly. Our transparency means you're never caught off-guard in the middle of critical work. If AI platforms truly believed in their value, why would they hide limits? At TESS, we show everything because we have nothing to hide.
Can I create custom GPTs like in ChatGPT?
Yes, and our system is actually more powerful. At TESS AI, you create custom agents through the AI Studio - a comprehensive tool that goes beyond ChatGPT's GPT builder. You can configure multimodal models, combining text, image, video, and voice AI into unified agents. Create business-specific solutions with Memory Collections that train responses using your company data. Deploy External Agents on your website or app. Set up API endpoints for custom integrations. Use cross-model collaboration so your agents can leverage multiple AI models in one workflow. ChatGPT's custom GPTs are limited to their ecosystem and models. TESS agents can combine 250+ models, integrate with external tools, and deploy anywhere you need them. You're not building on someone else's platform - you're creating true AI solutions with full control, transparent pricing, and unlimited deployment options.
