BrainLayer
Your AI has amnesia. BrainLayer fixes that.
Every architecture decision, every debugging session, every preference you’ve expressed — gone between sessions. You repeat yourself constantly. Your agents rediscover bugs they already fixed, and re-make choices the team already reasoned through.
BrainLayer gives any MCP-compatible AI agent persistent memory across conversations — and gives a whole fleet of agents a shared organizational memory: what one agent learns (a fix, a decision, what eroded and why) becomes experience the others inherit before they repeat the mistake. One SQLite file. No cloud. No Docker. Just pip install.
"What approach did I use for auth last month?" → brain_search
"Remember this decision for later" → brain_store
"What was I working on yesterday?" → brain_recall
"Ingest this meeting transcript" → brain_digest
"What do we know about this person?" → brain_get_person
Quick Start
pip install brainlayer
MCP examples require the Homebrew BrainLayer bridge. On Intel, replace
