RowBoat Labs
Build a persistent knowledge graph from your email and meeting notes to draft emails, prep meetings, and run background agents, open-source and local-first, storing everything as plain Markdown.
The verdict on RowBoat Labs: People and teams who want an AI coworker that builds a lasting knowledge graph from their email and meeting notes, then uses it to draft emails, prep meetings, and run background agents Rowboat used to be an IDE for building multi-agent systems; it has since pivoted into a local-first AI coworker built around a persistent knowledge graph assembled from your email and meeting notes. Pricing: Free open-source local application; chosen model-provider and infrastructure costs are separate. A current paid hosted tier has not been confirmed..
Best For
People and teams who want an AI coworker that builds a lasting knowledge graph from their email and meeting notes, then uses it to draft emails, prep meetings, and run background agents
Standout Feature
A persistent, linked knowledge graph built from your own email and meeting notes, stored as portable plain Markdown rather than locked into a proprietary format
TL;DR
A distinctive local-first AI coworker built around a persistent knowledge graph, still a young product following its pivot from a multi-agent IDE, so expect the real-world track record to keep developing.

Draft email replies from earlier threads, meeting notes and a growing knowledge graph, then review facts, recipients and commitments before sending. For self-managed use, the documented Gmail OAuth setup takes work, and recent synchronization fixes make a current-context check important. Apache-licensed source avoids a software license fee, but model usage, hardware and optional services still cost money; paid plans are separate. Hosted models and external connectors may receive supplied content even when the knowledge files stay local.

Prepare a meeting brief from accumulated emails, transcripts and linked notes, with Calendar context and editable Markdown available for checking. Desktop installers help, but self-managed Google OAuth and model configuration take work, and the brief is only as useful as the context collected. Budget for the chosen inference path and hardware rather than treating free source as free operation; paid plans are a separate option. Review the brief against source material before relying on it or taking follow-up action.

Overview
Not yet reviewedProduct quality is assessed from original evidence. How reviews work.
Rowboat is a local-first AI coworker that turns your emails and meeting notes into a persistent, linked knowledge graph, drafting emails, prepping you for meetings, and running background agents on your behalf as that context grows. It stores everything as plain Markdown on your machine, so your notes and knowledge graph stay portable and readable outside the app rather than locked into a proprietary database. Rowboat is open-source and self-hosted, and lets you choose your own underlying model rather than locking you into one provider. As the knowledge graph accumulates context about people, projects, and decisions from your inbox and meetings, Rowboat's background agents can draft follow-up emails, surface relevant history before a meeting, and help maintain that context as new information is captured.

- • Persistent knowledge graph keeps context from email and meetings readily usable
- • Local-first and open source, with data stored as portable plain Markdown
- • You choose your own underlying model rather than being locked to one provider
- • Self-hosting the local-first option still requires some technical setup
- • Newer product positioning after a pivot from its original multi-agent IDE, so real-world track record is still building
Key Features
- Knowledge graph built from email and meeting notes
- Background agents that draft emails and prep meetings
- Local-first storage as plain Markdown
- Open source with your choice of underlying model
Our Take
As that graph accumulates context about your people, projects, and decisions, background agents can draft emails, prep you before meetings, and help maintain that context as new information is captured. Storing everything as plain Markdown on your machine means your knowledge stays portable rather than locked into a proprietary database, and you can choose your own underlying model. It's open-source and free to run as a self-hosted, local-first application. Because this is a recent pivot, expect the real-world track record, and details like whether a hosted plan is still offered, to still be developing relative to more established knowledge-management tools.
