Recall that actually works
Hybrid semantic + keyword search returns only what's relevant to the task in front of you — not a pile of noise.

Your AI coding agent has amnesia. Cure it in one command.
Persistent memory for your AI coding agent. It remembers every session — so you stop re-explaining the same context, every day. Local, free, private.
Works on macOS, Windows & Linux. Node ≥ 22.
Works with your agent — five harnesses, one shared memory

Why it exists
Stop being your agent's memory.
Every session, it starts from zero. agentbrainsystem remembers — captures each one, recalls what matters, hands-free.
Set it once. Forget it forever.
Captures each session when it ends and feeds the right context back at the next start. One command — then it's invisible.

Your code never leaves your laptop
100% local and offline. No cloud, no account, no API keys required, no telemetry. The model downloads once, then runs offline.

How it works
Three steps. Zero effort.
-
Capture
Hooks (or an OpenCode plugin) auto-ingest every coding session when it ends — $0, no LLM.

Store
Embedded locally on your machine, fully offline. Nothing is uploaded.

Recall
Hybrid semantic + keyword search surfaces relevant memory — at session start and on every prompt, as you work.

FAQ
The honest answers.
Does it send my code anywhere?
No — by default everything runs locally and offline: no network calls, no telemetry, no account. The one exception is a hosted LLM you explicitly opt into at setup (local Ollama stays fully offline).
Does it cost anything?
No — $0 by default. Local embeddings, no API keys required.
abs setup offers a guided, skippable LLM step that sharpens recall — local Ollama is $0 and offline, or any hosted OpenAI-compatible endpoint; your key is never stored. Skip it and recall still works.Which agents does it work with?
Five harnesses — Claude Code, Codex CLI, Gemini CLI, GitHub Copilot CLI and OpenCode — each via MCP, with hands-free session capture and context injection through that harness's native lifecycle. The same local memory is shared across all of them.
Is it open source?
Fully — on GitHub. Fork it, read every line.
