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 — but only inside the browser profile where you indexed it. Vault takes it further: one encrypted memory that syncs across supported desktop devices and backs itself up automatically. Mobile access is planned for a future update. MCP remains a separate, free desktop feature — Vault simply makes it more useful by bringing more of your history together. The first 100 founding members lock in half price for life.
A stronger local archive
Bring more of your history together.
Index in one browser, then keep your history securely available across supported desktop devices. MCP is a separate free feature that can use your local LLMnesia archive with Claude Desktop, Cursor, and other compatible tools — no Vault required. Add Vault and that local archive can include the history you’ve synced from your other desktops.
Mobile Vault access is planned for a future update. Search runs locally on your desktop, where your key lives — so we can’t read your conversations.
What Vault unlocks
More than a backup — your history, finally working for you.
Mobile access, planned next
Mobile Vault access is on the roadmap for a future update. Vault begins with secure sync and backup across supported desktop devices.
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 one desktop, continue it in Claude on another. 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.

Questions
The details, answered.
What does “chat with your history” actually mean?
MCP is a separate, free feature that lets desktop AI tools use the conversations in your local LLMnesia archive. Vault is not required. If you choose Vault, its encrypted sync can bring more of your history together across supported desktops, making MCP more useful. Search still runs on your desktop, where your key lives and your archive can be decrypted.
Which platforms does it cover?
Everything LLMnesia already supports — ChatGPT, Claude, Gemini, Perplexity, Microsoft Copilot, DeepSeek, Grok, Mistral, Kimi, Qwen, Google AI Studio, Character.AI and Z.ai — brought together into one place.
Will it work on mobile?
Yes — mobile Vault access is planned for a future update. Vault begins with sync and backup across supported desktop devices, while MCP remains desktop-only because it runs locally on your desktop.
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, indexing, and MCP stay free. Vault is an optional add-on for people who want encrypted sync and backup across supported devices.
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.
