Overview

Open Brain (OB1) is an open-source personal infrastructure layer that unifies your AI tools around a single persistent database with vector search, a central AI gateway, and one chat channel. It enables any AI assistant (Claude, ChatGPT, Cursor, etc.) to share the same memory and context, eliminating the need for middleware or SaaS integrations.

Installation

Follow the Setup Guide (docs/01-getting-started.md) to build the full system in ~45 minutes, or use the AI-Assisted Setup (docs/04-ai-assisted-setup.md) with Cursor/Claude Code.

Problem solved

It solves the fragmentation of AI memory across multiple tools and platforms, where each AI has isolated context. By providing a single database and protocol, it ensures persistent, shared memory and reduces reliance on complex middleware or SaaS chains like Zapier.

What you can build

Developers can build a personal knowledge base that captures notes, messages, and documents from any source, with vector search for retrieval. Use cases include CRM systems with meeting prep, Obsidian vault imports, wiki compilers, and custom dashboards. The ceiling is a fully personalized AI ecosystem where every tool contributes to and queries a unified brain, enabling advanced workflows like provenance tracking and cost-optimized edge functions.

Bottom line

Open Brain is ideal for power users and developers who want a unified, self-hosted memory layer for their AI tools and are willing to invest in setup. It should be avoided by those seeking a plug-and-play SaaS solution or with minimal technical skills. The key trade-off is control and flexibility versus setup complexity and maintenance overhead.
