Graph-MIND

Your AI forgets everything when the session ends. This one remembers, and it never calls an LLM to do it.

88.8% on LongMemEval. Zero model tokens spent saving memory. Runs on your own PC.

Decide something with one agent on Monday. Ask another on Wednesday. It knows.

A decision made with one agent on Monday, recalled by another on Wednesday

Install

Windows: download Graph-MIND-Setup.cmd and double-click it, or in PowerShell:

irm https://raw.githubusercontent.com/goyohan0611-png/graph-mind/main/scripts/install.ps1 | iex

macOS / Linux:

curl -LsSf https://raw.githubusercontent.com/goyohan0611-png/graph-mind/main/scripts/install.sh | sh

No Python needed; nothing else to set up. Restart your AI apps afterwards. Already have Python? pip install graph-mind-memory && graph-mind-install. More: docs/install.md.

What it does

  • One shared brain for every agent in your terminal. Whichever coding agent or model you run, they all read and write the same memory: decide something with one, ask another later, it knows. Switch agents or models; the memory stays. Which ones
  • Remembers conversations word for word, on your own PC. Saving is a database write: no model call, no tokens. When a question depends on the past, the agent gets back the few thousand tokens that answer it. Korean and English.
  • One memory across your PCs. Run graph-mind folder share, then graph-mind folder <code> on the other PC (the AI tells you the command; it never moves your memory by itself, so a web page cannot either). Office network or Tailscale, over TLS, every line encrypted before it leaves a PC.
  • Yours. No account, no cloud of its own, no telemetry. Secrets are masked before anything is stored, and "delete the password I typed earlier" deletes it everywhere. docs/privacy.md
  • Teams, if you want them. Share a project's decisions and progress with teammates' AIs, never your personal memory; files stay in Slack and GitHub. docs/teams.md

Does it work?

Same 40 questions, same answer model, same official judge, pre-registered before anyone looked:

accuracy model tokens spent saving memory
Graph-MIND 85.0% 0
MemPalace 3.10.0 57.5% 0
Mem0 2.2.1 (open source) 52.5% ~640,000 per question

On all 500 LongMemEval questions: 88.8%. Against agentmemory on the same 499, its own published retrieval (95.2% R@5) handed to the same answer model and judge:

accuracy retrieval R@5 text the answer model reads, per question
Graph-MIND 89.0% 98.5% 3.4k tokens
agentmemory (its 5 sessions) 80.4% 95.2% ~16.5k tokens

Every question, answer and verdict is in research/runs/; method, failures and how to rerun it: docs/benchmarks.md.
