One library, every AI
ChatGPT, Claude, Gemini, Perplexity, Grok, Copilot, DeepSeek and the rest — all in a single searchable memory instead of a dozen walled gardens you have to check one by one.
Coming soon · LLMnesia Vault
All your AI chats. One memory you can actually use.
LLMnesia already searches your chat history across every AI tool. Vault takes it further — one encrypted memory that syncs to all your devices, backs itself up automatically, and plugs straight into your AI so it can draw on everything you’ve ever worked through. The first 100 founding members lock in half price for life.
The headline feature
Ask your entire history a question.
Vault connects your conversations to Claude, Cursor, and any tool that speaks MCP. Suddenly your AI can draw on everything you’ve already worked through — every decision, every draft, every dead end — no matter which assistant you used at the time. Your context stops being trapped in whichever tab you opened it in.
What Vault unlocks
More than a backup — your history, finally working for you.
On your phone, too
Your history syncs to every device. Look up what you worked through on your desktop from your phone on the train — the same searchable library, wherever you are.
Nothing ever lost
Platforms quietly delete old chats. Laptops die. Vault keeps an encrypted backup of everything you’ve indexed, so months of thinking never just disappear.
Encrypted end to end
Sealed on your device before it ever syncs. The key never leaves your hands. We can’t read your conversations — and neither can anyone else.
What you’ll do with it
The possibilities it opens up.
01
Pick up any thread
Start a problem in ChatGPT on your desktop, continue it in Claude on your laptop, check a detail on your phone. One continuous memory instead of a dozen dead-ended tabs.
02
Stop re-explaining yourself
Point your AI at your own history instead of re-pasting the same context every session. It already knows what you’ve decided, tried, and ruled out.
03
Build on your best thinking
Months of research, drafts and decisions become a knowledge base you can actually query — not scattered chats you’ll never find again.
Founding pricing
The first 100 pay half. For life.
The first 100 founding members lock in £4/month — half of the £8 launch price — and keep that rate for as long as they stay subscribed. After the first 100, the founding rate steps up to £6, still below launch. It’s our thank-you to the people who back it earliest.
- Chat with your entire history from Claude, Cursor & other MCP tools

Questions
The details, answered.
What does “chat with your history” actually mean?
Vault can expose your indexed conversations to AI tools through MCP — the open standard Claude, Cursor and a growing list of apps already support. Your assistant can then answer using your own past conversations as source material, not just its training data.
Which platforms does it cover?
Everything LLMnesia already supports — ChatGPT, Claude, Gemini, Perplexity, Microsoft Copilot, DeepSeek, Grok, Mistral, Kimi, Qwen and Google AI Studio — brought together into one place.
Will it work on mobile?
That’s a core part of the plan. Once your history is synced through Vault, it’s reachable from your phone — not just the browser where you first indexed it.
Isn’t syncing the opposite of local-first?
No. Your history still lives on your device. Vault lets your devices share an encrypted copy directly, with a key only you hold. What travels between them is an unreadable blob — same privacy promise, more reach.
Will the free version still work?
Always. Local search and indexing stay free, forever. Vault is an optional add-on for people who want their history synced, backed up, and usable inside their AI tools.
How is it private if it’s in the cloud?
Everything is encrypted on your device with a key we never see. What we store is meaningless without it. We can’t read your conversations, and we can’t hand over what we don’t have.
When does it launch?
We’re building it now. Join the waitlist and you’ll be first to know — and founding members lock in half price for as long as they stay subscribed.
Be one of the first 100 — at half the price, for life.
The first 100 founding members lock in half price for life, and everyone who joins before launch keeps a founding rate. It costs nothing to claim your place now — no card, no commitment — and you’ll never pay full price if you do.
