Rowboat (YC S24) is an open-source AI coworker that connects to your email, calendar, and meeting notes, then builds a persistent knowledge graph stored as plain Markdown files on your local machine. The graph is fully inspectable — it's just a folder of .md files you can open in Obsidian, edit, or commit to git. Using this local knowledge graph, Rowboat helps draft emails in your voice, prepares meeting briefs before calls, generates docs and summaries, and answers questions about your work history. It supports MCP (Model Context Protocol) for connecting external tools like GitHub, Linear, and Notion. Runs entirely on your machine with no data sent to external servers beyond your LLM API calls. The key differentiator is transparency. Unlike AI memory systems that store knowledge in opaque vector databases or cloud embeddings, Rowboat's knowledge graph is human-readable at every step. You can audit what it knows about you, delete specific facts, and understand exactly why it drafted an email the way it did.

Velo lets you record or upload anything — slides, PDFs, docs, screen recordings, websites — and instantly converts it into a polished video message narrated by a hyper-realistic AI avatar with lip sync, eye blinks, and natural gestures. The whole workflow runs in-browser with no downloads required. The key insight is async communication fatigue: teams are drowning in wall-of-text Slack messages and poorly-produced Loom videos, but nobody has time to polish a proper recording. Velo fills the gap by letting you share a PDF, pick a voice, and ship a professional-looking walkthrough in under two minutes. It launched on Product Hunt today and hit #1 with 464 upvotes — unusually strong traction for a non-developer tool. The avatar quality is notably better than earlier AI presenter tools. Early users are reporting it as a replacement for Loom in cases where they want a "polished" look without showing their face or spending time on editing.
Reviewer scorecard
“Inspectable Markdown-based memory is the right call. I can version-control the knowledge graph in git, grep through it, and actually understand what context my AI assistant has — that's more than I can say for any SaaS memory product. MCP support means it plugs into my existing toolchain.”
“The in-browser workflow is genuinely frictionless — paste a link, pick a voice, done. This is the kind of async communication tool I'd actually use instead of recording another mediocre Loom.”
“Self-hosted means you're on your own for setup, sync, and maintenance. Most people using AI coworker tools want them to just work — and polished competitors like Mem.ai and Notion AI have months of production hardening. The Markdown vault is clever but also fragile at scale.”
“AI avatars in 2026 still read as 'uncanny valley corporate' and that's going to cap adoption in informal team settings. Also no pricing transparency at launch is a red flag — freemium often means 'free for 30 seconds of video.'”
“Persistent, user-owned AI memory stored as plain text files is the foundation of truly personal AI assistants. When models can be swapped and knowledge graphs can be exported, you break vendor lock-in completely — Rowboat is building the right abstraction layer for the long term.”
“Async video is eating synchronous meetings and Velo's approach — no face, no setup, just content — could accelerate that significantly for distributed teams. This is what the next generation of internal communication looks like.”
“Having an AI that actually knows my past projects, writing style, and client relationships — stored in files I control — is exactly what I've wanted. Email drafting in my own voice based on real context beats generic ChatGPT outputs every time.”
“As a content creator I've been waiting for a tool that makes me look polished without a studio setup. The avatar quality here actually clears my bar — I'd use this for client-facing walkthroughs without hesitation.”
