Shared AI coding memory that saves tokens and learns daily

Hey Hunters 👋

I'm excited to launch Open Agentic Brain & Memory (OpenAB), an open-source shared memory for all your AI coding tools.

I use Claude Code, Cursor and Codex on the same projects every day. Each one starts blank, so I kept re-explaining my project and burning tokens and plan limits. So we built one memory they all share.

It's open source, so you can run it locally, own your data, or build the feature you want.

💸 Saves tokens: a briefing under 2,000 tokens instead of re-explaining

🧠 One tool learns it, every other tool knows it

🔌 Claude Code, Cursor, Codex, Antigravity, Kilo Code, Claude Desktop, ChatGPT desktop and any MCP client

📂 Doesn't start empty: learns from your existing projects on install

🌙 Learns every day while you sleep, lessons wait for your approval

⚡ Ready in 84 ms, recall over 10,000 memories in 28 ms

🔐 Local, encrypted, synced to your own private GitHub. No account

🧰 Syncs your skills across tools and machines

🍎 macOS and Linux · Free · Apache-2.0

Would love your feedback: how many tokens does your first day save you?
