Step 1
Build your private history
Install LLMnesia and import the older chats you want available. New conversations from supported AI platforms are captured automatically as you use them.
Your searchable archive stays on this computer.
For your desktop AI
Let your desktop AI use what you already learned.
LLMnesia already keeps your ChatGPT, Claude, Gemini and other AI chats searchable. Its free MCP connection lets Claude Desktop, Cursor, Codex and other desktop AI apps search that history, answer from it, and link back to the original conversations. Everything stays on this computer.
Install LLMnesia first. Then open Full settings → Connect desktop AI and follow the steps shown for your computer.
Guided local setup
Three clear steps.
Settings walks you through the right order for Windows or macOS—no guessing which app to open or which command to run.
Step 2
Follow the guided connection
Open LLMnesia → Full settings → Connect desktop AI. Enable automatic sync, install Node.js if prompted, then copy the complete command into PowerShell on Windows or Terminal on macOS.
Follow every step shown for your computer. Windows Claude Desktop users have one additional guided step.
Step 3
Restart, then ask naturally
Fully quit and reopen the browser and connected AI app when Settings tells you to. Then ask what you decided, where you solved a problem, or what you discussed before.
Answers include links back to the original chats whenever those links are available.
Made for deep work
Ask about projects you already worked through.
Ask in your own words. Your desktop AI searches your history locally and brings back the useful context, with sources you can open.
Revisit an important decision
“Why did we choose an invite-only beta?”
Bring back the options, trade-offs, and decision you reached without remembering which AI app or conversation contained it.
Resume a complex project
“Where did I leave off planning the migration?”
Find the latest useful thread, recover what you already worked through, and continue from the next step instead of reconstructing the whole project.
Reuse research across tools
“Pull together what I learned about local-first apps.”
Combine useful context from ChatGPT, Claude, Gemini, and other supported sessions into one sourced answer you can inspect.
Reuse your working preferences
“What does my preferred project brief look like?”
Recover the formats, patterns, and preferences you have already established. Suggested memories remain under your review and control.
Works where you do
Connect the desktop AI apps you use.
The installer connects supported apps on this computer, preserves their existing settings, and backs up any configuration it changes.
Claude Code
Connected automatically for your user account when Claude Code is installed.
Claude Desktop
Connected automatically on macOS. Windows users get one additional guided Claude extension step.
Cursor
Connected automatically, with existing settings preserved and backed up.
Codex
Connected through the Codex CLI, including the copy bundled with supported desktop apps.
Other desktop clients
For other local MCP apps, setup prints a standard connection block you can paste into their settings.
Sources included automatically
An answer you can verify.
Your assistant answers from the conversations LLMnesia found and includes links back to the originals whenever they are available. You can check the context instead of trusting a detached summary.

Start invite-only, then open access gradually.
answerYou chose a two-week invite-only beta so the team could watch onboarding closely, fix the rough edges, and collect feedback before opening access more widely.

Good to know
The essentials.
Do I need the browser extension?
Yes. The MCP package does not collect conversations on its own — it only reads the corpus that the LLMnesia browser extension builds. Without the extension, every search comes back empty. The extension is free for Chrome and Microsoft Edge and captures ChatGPT, Claude, Gemini, Character.AI, Grok, DeepSeek and the rest of the supported platforms as you chat.
Does anything leave my device?
No. The corpus, the search index, and the MCP server all stay on your machine. The only network call the extension makes is the limited, anonymised product analytics covered in the privacy policy — and that never includes conversation content, prompts, replies, or search queries. The MCP server itself makes zero network calls.
Which clients can reach the server?
Desktop apps that can run a local MCP connection, including Claude Code, Claude Desktop, Cursor and Codex. Browser-only AI websites cannot directly reach a local connection on your computer.
What do I need to install?
The LLMnesia browser extension and Node.js 22.13 or newer. Settings detects whether you are on Windows or macOS, links to the right Node installer, tells you exactly how to open PowerShell or Terminal, and gives you the complete command to copy.
Is MCP the same as Vault?
No. MCP is free, local-only, and designed for desktop AI clients; it works without Vault. Vault is an optional paid feature for encrypted sync and backup across supported desktop devices. Using Vault can make MCP more useful by bringing more history into your local archive. Mobile Vault access is planned for a future update.
Bring your history with you
Your AI conversations can keep working for you.
Install LLMnesia, choose the history you want available, then open Full settings → Connect desktop AI. The guided setup takes it from there.
