Brain OS is a biologically-inspired, central cognitive engine written in pure Rust. Instead of every script, coding assistant, and chat UI keeping its own isolated, fragmented context, Brain OS acts as your single source of truth. It routes intents through a Thalamus, scores importance via an Amygdala, and stores everything in a unified Hippocampus (FTS5 + HNSW Vector Search). Whether you connect via HTTP, WebSocket, gRPC, or MCP, your AI tools now share one localized, ever-growing memory that runs 24/7 on your machine. Your data never leaves your hardware. Your AI never forgets. 👉 Full documentation — architecture, API reference, operations guide, and more. --- Quick Start See full install guide below for details. --- How It Works Every input — regardless of protocol — flows through the same pipeline: The memory engine combines vector search (HNSW) with full-text search (BM25 FTS5), fuses results via Reciprocal Rank Fusion, and reranks by importance and recency. A forgetting curve runs every 24 hours to prune low-value memories and promote reinforced episodes to permanent semantic facts. Beyond memory: the kernel it grew into Memory is the hook — but the same daemon also mediates what your AI tools can do. Every capability it exposes — search the web, run a sandboxed command, send a notification, probe a host, audit its own config — is a typed entry in one capability manifest , each tagged with a safety tier and routed through the sa","default_branch":null,"files":null,"tree":[],"storefront":"/r/keshavashiya","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/keshavashiya/brain/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
