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.

TrendRadar (v6.6.1) is an AI-driven public opinion and trend monitoring system that aggregates multi-platform news feeds, RSS sources, and social signals with AI-powered smart filtering, sentiment insights, trend prediction, and multi-channel notifications. It supports WeChat, Telegram, Slack, email, ntfy, and Bark for alerts. The v6.6.0 update added a major new feature: MCP integration that lets AI agents query trend data conversationally without writing any custom integration code. The system uses LiteLLM for unified model support across OpenAI, DeepSeek, Gemini, Claude, and other providers, making it model-agnostic. Recent updates added browser-based HTML reports with dark mode, real-time search within reports, and 30-second Docker deployment. It has accumulated 54,000+ GitHub stars and continues to trend as MCP tooling becomes the standard for AI agent integrations. For competitive intelligence teams, researchers, and developers who need to monitor a domain and surface signal from noise, TrendRadar's combination of broad source aggregation, AI filtering, and now native MCP support makes it a practical daily driver. The MCP integration means it slots directly into agent workflows — an agent can ask "what's trending in quantum computing this week" and get a structured answer from your monitored feeds.
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 MCP integration is the v6.6 unlock that makes TrendRadar genuinely agent-native. Querying curated trend data conversationally without writing integration code is exactly what agentic workflows need. 54k stars says the core monitoring functionality is solid — this is a battle-tested tool that's now been MCP-ified, not a new experiment.”
“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.”
“TrendRadar is fundamentally as good as its source configuration — garbage feeds in, garbage trends out. AI 'smart filtering' is still imprecise for niche domains without significant prompt tuning. If you need real competitive intelligence for a B2B vertical, you'll spend considerable time configuring and calibrating sources before getting reliable signal. The out-of-box setup is mostly consumer news feeds.”
“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.”
“MCP is rapidly becoming the connective tissue of AI agent stacks, and tools with good MCP interfaces become ambient infrastructure for agents rather than just human-facing dashboards. TrendRadar's MCP bot enables a class of agent workflows — monitor a space, detect a signal, take an action — that previously required bespoke integration work. This is a building block for autonomous research agents.”
“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.”
“For creators tracking trends across niches to identify content opportunities, TrendRadar's aggregation plus AI filtering is a significant time-saver over manually monitoring dozens of feeds. The HTML reports with dark mode and real-time search make the output actually useful for review, not just a firehose of raw items.”
