Mother Brain

Mother Brain is a desktop application that solves a fundamental problem with AI assistants: they forget everything when a session ends. It creates a persistent memory layer that works across any LLM, chatbot, or coding agent — so your AI remembers your codebase, past conversations, and team knowledge from one session to the next. The app runs locally on macOS (Windows and Linux coming soon) and deploys vector databases to your own cloud infrastructure via Cloudflare Workers and Supabase.

The tool indexes codebases, Git repos, PDFs, images, and other files into a searchable knowledge graph. It includes features like Code Index for vectorized code search with 98.5% token reduction, a 3D knowledge graph visualization, and Read-Only Memory containers for curated knowledge bases. Mother Brain uses a Tauri + Rust desktop app with a React frontend, and it supports role-based access control so you can give different permissions to team members and AI agents. Setup takes about 10 minutes — download, launch, sign in, and click Deploy.

Mother Brain is best for developers and teams who work with AI coding assistants like Claude or ChatGPT and want those assistants to have long-term context. It's also useful for teams that need to share knowledge across humans and AI agents without vendor lock-in. At $25 per year with no tiers or upsells, it's a straightforward alternative to platform-specific memory solutions or developer libraries that require writing Python code.
