Show HN: Rowboat – Open-source, local-first alternative to Claude Desktop
Why it matters
Open-source desktop app that reimagines how AI assistants integrate into knowledge work by embedding Claude capabilities directly into domain-specific work surfaces (email, meetings, coding, notes) rather than relegating AI to a separate chat interface. Targets the growing demand for AI tooling that understands context across workflows.
Key signals
- Open-source, Apache-2.0 licensed
- Local-first architecture with plain Markdown file storage
- Work surfaces: email client with style learning, meeting notes (Granola-style), isolated browser, parallel coding with Claude Code/Codex orchestration, Obsidian-style notes
- Knowledge graph indexing across all surfaces for contextual awareness
- Extensible via custom web app builder with background agents
- Works with any LLM including local models (Ollama, LM Studio)
- Community app ecosystem at launch
- Built by team with prior enterprise AI experience (P&G support reps use case)

The hook
Not a chat app. Rowboat brings Claude into your actual workflow — email, meetings, code, notes, all in one local-first workspace.
Claude’s desktop app is brilliant, but for our own daily work we kept wanting it to be less like a chat app and more like a full-fledged work app. Rowboat is our attempt at that, including the ability to build your own work surfaces inside Rowboat (more below).
Our repo is https://github.com/rowboatlabs/rowboat, and there’s a demo video here:
In a previous startup, we built a deep-learning product for enterprise support reps, including teams supporting P&G brands. Models took live notes, suggested replies, and recommended actions while support reps were on calls or handling emails. One lesson stuck with us: it's not enough for the AI to be right, the help has to show up where the work is happening.
So we added what we came to call “work surfaces”: dedicated areas for email, meetings, notes, browser, and parallel coding, where the assistant can help inside the workflow itself rather than only through chat:
- Email client: Rowboat has a simple email client that sorts incoming emails into important vs. everything else, and pre-creates drafts for important emails. As you edit and send emails, it takes notes on your style, so future drafts get closer to your voice.
- Meeting notes: We built a Granola-style local meeting notetaker. Notes are stored as plain Markdown files on your machine. After a meeting, Rowboat feeds the notes back into the knowledge graph and updates the relevant people, project, and topic notes.
- Browser: We added a built-in browser, isolated from your main one, where you can log in only to the accounts you want the assistant to help with. The assistant uses browser-use skills to navigate websites.
- Parallel coding: The code-mode inside Rowboat lets you spin multiple instances of Claude Code or Codex and either work with them directly or let Rowboat use your work context to orchestrate them. We built an ACP (Agent Client Protocol) client in Rowboat for this.
- Notes: Rowboat has an Obsidian-style local note-taking system. It comes with graph view, ...
