Rowboat brings a local-first AI coworker to the desktop

A new open-source tool called Rowboat wants to turn AI assistants into a full workspace rather than just a chat window. The developer, posting under the handle segmenta, introduces the project in a Show HN post on Hacker News, describing it as a local-first alternative to Claude Desktop.

The team behind Rowboat previously built AI tools for enterprise support teams, including staff supporting P&G brands. That experience shaped their approach: help needs to appear inside the actual workflow, not just in a chatbot. Rowboat’s GitHub page describes the app as a desktop AI coworker with a memory of the user’s work.

Work surfaces instead of chat windows

Rowboat organizes its features into what the makers call “work surfaces”. These include an email client that sorts messages by importance and drafts replies in the user’s writing style, a local meeting notetaker that stores transcripts as Markdown files, an isolated built-in browser for automated web tasks, and a code mode that runs multiple instances of Claude Code or Codex in parallel.

Users can also build custom work surfaces, described as small web apps with their own interface and background agent, and share them through public GitHub repositories.

Knowledge graph and local data

All of these surfaces draw on a knowledge graph that indexes emails, meetings, and notes to give the assistant lasting context, rather than reconstructing it from scratch each time. Data stays on the user’s machine as plain Markdown files, according to the GitHub repository. Rowboat is released under the Apache 2.0 license and supports both hosted models and local ones run through Ollama or LM Studio.
