Open-source AI coworker that builds a knowledge graph from your emails and meetings, then acts on it locally - no cloud required

Ever wished you had an assistant who actually remembers every decision, every project detail, and every conversation thread? Rowboat is that AI coworker, but it runs entirely on your machine. It ingests your Gmail, meeting notes, and documents to build a persistent knowledge graph, then uses that context for genuinely useful tasks like “Build me a deck about our Q3 roadmap” or “Prep me for my meeting with Sarah.” Unlike ChatGPT which forgets everything after each conversation, Rowboat accumulates institutional knowledge over time.

What sets it apart is the local-first approach - your data never leaves your machine, yet you get enterprise-grade AI capabilities. The knowledge graph is stored as simple Markdown files you can edit directly, and it supports voice memos that automatically extract key insights. With 6.8k stars and Y Combinator backing, it’s gaining serious traction among developers who want AI assistance without sacrificing privacy. The setup takes minutes, supports all major platforms, and integrates with Google Workspace out of the box.
