The best open-source personal memory engine for AI coding assistants.

Every claim ships with the harness that proves it. Run the benchmarks yourself.

Persistent memory for any MCP client. Local, encrypted, verbatim recall via vector search + knowledge graph. MIT.

iai-pme

Your AI assistant forgets you every session. iai-pme gives it a memory that doesn't.

Independent Autistic Intelligence — a personal memory engine. Fully local, ambient. Works with Claude Code, Claude Desktop, Cursor, Codex CLI, Gemini CLI, Cline, Continue.dev, Zed, Cherry Studio, Goose, Aider, Hermes, OpenClaw, Le Chat, Kimi — anything that speaks MCP-over-stdio.

What it is

A local server that speaks the MCP protocol and gives Claude, and any other MCP-compatible assistant, a long-term memory. It captures every turn of every session verbatim, organizes those captures over time into a personal map of who you are, and serves a small slice of relevant memory back at the start of each new conversation. You never have to say "remember this" or "what did we say last time?".

I built this for myself. It worked. I've been running it daily for months, and now I'm sharing it. The benchmarks were mostly for my own curiosity. I wanted to know if it actually works or if I'd just gotten used to it.

Under the hood it's not a wrapper around someone else's vector store and graph library — the parts that matter are my own code: the storage engine, the community-detection algorithm, the hyperdimensional memory substrate, and a native engine that makes it fast. More on that in Built our own.
