One memory. Every AI. Yours.
Stop re-explaining yourself to every AI. Persona turns your files, emails, and conversations into a single memory layer β and gives it to Claude, ChatGPT, Cursor, and any MCP agent. Your raw data never leaves your device.
More than a memory box β a living model of your world that updates as your world changes.

Why a Memory Layer?
Your knowledge shouldn't be locked inside a single AI β or forgotten the moment a chat ends.
Unified Memory Layer
One knowledge graph fed by your files, emails, and conversations across every AI agent β Claude, ChatGPT, Cursor, and any MCP-compatible client. Switch agents without losing context.
You Own Your Memory
Your raw files and messages never leave your device β only structured facts sync to your private graph, and you can review, export, or delete any of them anytime. Your data, your rules.
Set Up Once
Connect your sources and add a single instruction to your AI. From then on it reads and writes your memory on its own β no "remember thatβ¦" every time. Simple enough for anyone.
Answers, Not Just Search
Ask in plain language and get structured answers backed by their sources β not a pile of matching documents. Under the hood: a GraphRAG knowledge graph of facts and relationships.
Stays True Over Time
Most memory tools just pile up notes and quietly go stale. Persona actively maintains the truth β resolving contradictions and retiring outdated facts as your world changes. "Alice used to work at A, now at B." No stale data, no duplicates.
Works With Every AI
Built on the open Model Context Protocol, so it plugs into any MCP-aware agent out of the box β Claude, ChatGPT, Cursor, and more. No vendor lock-in, no proprietary plugins.
How It Works
From your real data to every AI β in four steps
Install Persona Node
A lightweight app on your computer indexes your files, email, and chats β locally. Your raw content never leaves the device.
It Builds Your Memory
Persona extracts the facts that matter into a private knowledge graph β and keeps it current as things change.
Connect Your AI
Add Persona to Claude, ChatGPT, Cursor, or any MCP agent with a single instruction. That's the whole setup.
Every Agent Remembers
From then on your agents read and write the same memory β no re-explaining, no lost context when you switch tools.
Powered by Your Real World

Persona Node app is available for Windows and macOS today. The Linux build is coming soon.
