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
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 to every device, backs itself up automatically, and travels with you, so the AI tools on your desktop can draw on all of it through MCP. The first 100 founding members lock in half price for life.
The headline feature
Index in one browser, ask from another machine entirely. Vault syncs your full history to every device you use, where LLMnesia’s local connector serves it to Claude Desktop, Cursor, and any tool that speaks MCP. 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, or where you were sitting.
Search runs where your key lives. That’s what end-to-end encrypted means, and it’s why we can’t read your conversations.
What Vault unlocks
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.
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.
Platforms quietly delete old chats. Laptops die. Vault keeps an encrypted backup of everything you’ve indexed, so months of thinking never just disappear.
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
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.
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.
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 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
Vault can expose your indexed conversations to desktop AI tools through MCP — the open standard Claude Code, Codex 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. This runs on your desktop, where your key lives: search happens on a device that can actually decrypt your archive, which is exactly what end-to-end encrypted means.
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.
Your archive does: once your history is synced through Vault, it’s backed up and reachable from your phone, not just the browser profile where you first indexed it. Chatting with your history through MCP is a desktop feature — MCP tools run on the desktop, and search has to run where your key lives. So: sync, backup and lookup everywhere; MCP on your desktop.
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.
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.
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.
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.
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.
