Rowboat
Local-first AI coworker with persistent knowledge graph, no cloud lock-in
Expert verdict
Ship
3-1The Panel's Take
Rowboat is a local-first, open-source AI coworker that connects to your email and meeting notes, builds a persistent Obsidian-compatible knowledge graph from them, and uses that context to draft documents, meeting briefs, slide decks, and emails. It works with local models via Ollama or LM Studio, or with hosted APIs, and supports MCP for connecting external tools. The design philosophy is deliberately anti-cloud: all data stays in plain text Markdown files you can read, grep, and version-control. The knowledge graph is transparent — you can open it in Obsidian and see exactly what the AI knows about you. No black-box embeddings in a proprietary vector store, no "trust us with your emails" data agreements. Rowboat implements what Karpathy described as a "long-term memory coworker" — an AI that compounds value over time because it actually knows your history, your projects, and your terminology. TypeScript codebase, Apache 2.0 license, surging on GitHub trending this week.

“Plain-text persistence + MCP + local model support is the right architecture. It'll survive AI winters and API deprecations. The Obsidian compatibility alone is a killer feature for the PKM crowd that already lives in that ecosystem.”
“The 'knowledge graph from email' promise is where these tools historically fall apart — noisy inboxes produce noisy graphs. And 'local-first' often means 'labor-intensive setup.' The abstraction is right but execution on messy real-world data is hard. Watch the 1-month reviews.”
“Personal knowledge infrastructure that you own is becoming the moat in AI-augmented work. Rowboat's transparent, portable approach builds durable value. In two years the question won't be which AI assistant you use, but which knowledge graph underlies it.”
“Drafting meeting briefs and decks from accumulated context is the workflow I've wanted for years. The Obsidian integration means my notes and my AI context stay in sync naturally — no separate import/export dance.”
