Your knowledge is the one asset that outlives every product built on top of it.
The next assistant will be smarter than this one, and the one after that smarter still. What makes any of them useful to you is the same thing every time: what you know, what you've decided, what you've been through. That should never be the thing you lose when you switch.
Every AI assistant is asking to read your life. Keptmind is the place they read from — encrypted, every read logged, revocable in one switch. And what they learn about you is written back to you, in plain text you keep forever.
One person's knowledge: family, home, health, recipes, ideas, work, money, the unfinished novel, and everything they have told an AI assistant.
Every new assistant asks for the same thing:
Access
in its system, in its format, under its terms. The better it knows you, the harder it is to leave. That memory is the moat.
You hit a wall. Starting over with a new assistant means teaching it your life from zero — or handing everything over again, to someone new.
One instrument between your life and every agent.
Pick an agent. Flip what it may read. Watch every read happen. Sealed rooms ask you first. What the agent learns is written back to your vault — and one button ends it all.
Markdown and simple files. Readable in fifty years, by any tool, with or without us.
Whatever an agent learns or produces about you lands in your vault — not only in theirs.
Trying a new agent? Give it three folders, not your life. Scope by folder, file, time and purpose.
Who read what, when, and why — a complete ledger, in plain text too.
Medical records, money, legal. Nothing enters without your yes, case by case.
An agent sweeping everything it can reach gets paused and reported to you.
Cancel an assistant and its access to your vault ends with it. No wall, no hostage.
We sell protection, never access. No ads, no training on your data, no data brokering.
You choose who holds the key. We show you the price of each choice.
You hold the only key. We store ciphertext we cannot read. Agents work only while your device unlocks them.
You issue a derived key that expires — an hour, a week — so agents can work while you sleep. It dies on schedule.
Recovery through people you trust, or held in escrow, so a lost device isn't a lost life.
This is where we will spend our research. The line we won't cross: our business is protecting your data — never being the one who hands it out.
You run Claude, ChatGPT, local models and your own scripts over the same notes. Point them all at one vault — over MCP or as a folder — with scopes, a ledger, and memory that doesn't fork per tool.
Three clinics, two countries, one history. Keep your records in a sealed room, and let a health assistant read one visit — once — with your yes.
A new assistant wants everything. Give it three folders for a week, read its ledger, and decide. Walk away, and what it learned stays with you.
A vault for your personal knowledge that AI agents read from and write to — with your permission. Everything is stored as plain text you own, every read is logged, and any agent's access can be revoked in one switch.
You choose. You can hold the only key, or allow a time-limited delegated key so agents can work while you're offline. Either way, our business is protecting your data — never brokering access to it.
Its access to your vault ends the moment you revoke it or cancel. Everything it learned about you stays in your vault, in plain text, ready for the next one.
No, and we'll never claim to. We can limit what it reads, show you every read, flag bulk reads, and cut future access. What a provider already copied is governed by their terms and the law.
Through open protocols like the Model Context Protocol (MCP) and a plain filesystem view, so any agent that can read files or speak MCP can use your vault — with scoped permission.

Thank you. Your mind, kept.
If this matters to you, the best thing you can do is send it to one person who would care.
