ArcBrain – Persistent AI Memory Layer
Persistent AI memory for Copilot, Cursor & Claude Desktop
ArcBrain is a local memory server that connects VS Code Copilot, Claude Desktop, and Cursor simultaneously via MCP. Every 5 minutes, it extracts structured facts from your AI sessions — not raw logs, but knowledge like "Auth uses JWT with 15-min expiry." Facts age through Working → Operational → Canonical layers. Fix a bug in one tool, the others know in minutes. All data stays on your machine. Supports OpenAI, Anthropic, Gemini, Grok, or local Ollama.
Hey Product Hunt! 👋 Wil here, solo dev and maker of ArcBrain.
I built this out of pure frustration. Every morning: open VS Code Copilot, re-explain my project. Switch to Claude Desktop, re-explain again. Open Cursor, re-explain a third time. I was the human clipboard between my own tools.
Six months later — ArcBrain. It runs locally, connects to all your MCP-compatible AI tools simultaneously, and keeps a shared memory that actually ages and improves over time. Fix something in Copilot → Claude knows about it 5 minutes later. No copy-paste. No "as I mentioned earlier."
If you've ever re-explained your codebase to AI more than once this week, this was built for you.
Happy to answer anything — throw your questions in the comments.
