Tessera
Compare
Tessera compared to using an AI app directly
Same models. A different place to keep the memory.
An honest comparison of two arrangements: memory held inside one AI product, and memory held on your side as a layer that works with several. Including where a single app is genuinely fine.
Tessera is a private AI memory app. It is not an AI itself. It is the memory layer between you and whichever AI you use, which is the entire difference this page is about.
The one difference everything else follows from
Most AI apps now keep some record of you. That record belongs to the product holding it. It makes that product better, and it stops at the edge of that product.
A memory layer inverts the arrangement. The record is yours, kept separately from any model, and handed to whichever model is answering. Everything below is a consequence of that one difference.
Side by side
Memory inside one app, or memory on your side
| A single AI app | Tessera | |
|---|---|---|
| Who holds what is remembered | The AI company | You |
| What the AI company knows about you | Your account, your history, your profile | Nothing that identifies you |
| Can you read all of it | Usually a summary, sometimes nothing | Every fact, line by line |
| Can you correct it | Sometimes, indirectly | Edit any fact in seconds |
| Works with other AI models | No | Several leading models, one subscription |
| Switching models mid-conversation | Not possible | Context carries over intact |
| Export | Varies, often partial | A full copy on request |
| Deletion | Varies | One fact or the whole account |
| Training on your conversations | Depends on the provider and your settings | Business tiers, where training is off by default |
| Advertising business behind it | Depends on the company | None. Subscriptions only |
| If you stop paying | Memory usually stays with them | Read or delete your memory either way |
What you actually feel day to day
You stop re-explaining. Both arrangements fix this within their own walls. The difference shows up the first time you use a different model and find yourself a stranger again.
You can check what it thinks it knows. A wrong fact is worse than a missing one, because it quietly shapes every answer. Being able to open the list and fix a line is a small feature that changes how much you trust the thing.
You are not choosing a model for life. Different models are better at different questions, and that ranking changes every few months. Keeping the memory separate means changing your mind costs nothing.
Where a single AI app is genuinely fine
If you use AI occasionally, for questions that stand on their own, and you do not mind supplying context each time, a single app is enough and you do not need this. That is a real answer, not modesty.
The case for a memory layer strengthens when your questions depend on your actual circumstances, when you use more than one model, or when you want to see and move what is stored about you.
What Tessera does not claim
- It is not a better model. Tessera does not answer your questions. Leading AI models do, and they are the same models either way.
- It is not free. Ten days free, then a subscription. If price is the deciding factor, a free app wins.
- It is not a lock on your data. Everything exports, which is the point.
The short version. The models are the same. The question is whether the memory of your life sits inside somebody's product or on your side of the conversation, where you can read it, correct it, and take it with you.
Questions
The ones worth asking before switching
What is the difference between Tessera and an AI app with memory?
The difference is where the memory lives. Memory built into a single AI app is held by that company, for use in that product: you usually cannot read all of it, move it, or take it with you. Tessera keeps the memory on your side of the conversation, so you can read every line, edit it, export it, delete it, and use it with several leading AI models.
Do I still need my existing AI app?
Plenty of people keep one for work, or for a specific feature they like. Tessera is not trying to be the only place you type. It is trying to be the place your context lives, so that starting somewhere else does not mean starting over.
Is one subscription really cheaper than several?
If you currently pay for more than one AI app, yes, one subscription covering several leading models replaces several bills. If you use exactly one free app and are happy with it, Tessera is a paid product and you should decide it is worth it on the memory, not on the price.
When is a single AI app enough?
When you use it occasionally, for self-contained questions, and you do not mind re-explaining yourself. The case for a memory layer gets stronger the more your questions depend on your actual life, and the more you care about being able to see and move what is stored about you.
