Rowboat is an open-source personal AI assistant and AI coworker with built-in memory, documents, a whiteboard, and email. It can work solo as your second brain or collaborate with your team, keeping context across conversations instead of starting from zero each time. Built by Rowboat Labs, the project has over 18,000 stars on GitHub and was actively developed in October 2026.
Rowboat is designed around long-term collaboration. Its memory layer remembers your projects, preferences, and past work, so the assistant gets more useful the longer you use it. Around that core it bundles the tools a coworker needs: shared documents it can read and edit, a whiteboard for visual thinking, and email integration so it can help manage your inbox and correspondence. Multi-agent orchestration under the hood lets it break bigger jobs into pieces and carry them through, and because it is open source under Apache-2.0, you can self-host it and keep your data yours.
Rowboat is free and open source under the Apache-2.0 license. Self-hosting costs nothing beyond your infrastructure and any model API usage you connect.
Rowboat suits professionals and small teams who want an AI coworker that remembers context across weeks, not just within one chat. If you like the idea of an assistant that knows your documents, mail, and ongoing projects, Rowboat is worth a look.
