Imagine asking a very thorough assistant to spend an hour reading Reddit threads, YouTube comments, posts on X, and a handful of other corners of the internet — all from the last 30 days only — and then hand you back a written summary with actual links to where they found things. That's what this tool does, automatically, in the time it takes to make a coffee.
It's called last30days, and you trigger it with one short command inside Claude Code (Anthropic's AI assistant for tasks like this). It fans out across eight sources — Reddit, X, YouTube, TikTok, Instagram Reels, Hacker News, Polymarket, and the open web — ranks what it finds by how much attention it's getting, and writes you a narrative. Not a vague AI summary. A grounded one, with citations.
Most of us do market research the slow way: we Google something, skim a few articles, maybe check Reddit if we remember it exists. This collapses that into minutes.
Think about what you could do with a real-time pulse on your market. Before launching a new service, you'd know what customers are complaining about with similar offerings right now — not six months ago. Before hiring for a new role, you'd know what's actually in demand. Before investing in a tool, you'd know what practitioners are saying about it this week.
It's already earned over 8,000 stars from people who build software for a living, which is a reliable signal that it's genuinely useful.
Claude Code — a version of Anthropic's Claude AI that can run tasks and use tools on your computer, not just chat.
Agent — an AI that doesn't just answer questions, but goes off and does a series of steps to complete a task on your behalf.
Citations — in this context, actual links back to the Reddit post, YouTube video, or tweet the AI found — so you can verify it yourself.
Hacker News — a popular forum where software developers and startup people share and discuss what's new in tech.
If you're curious, show this to whoever handles research or marketing at your company and ask: what questions do we answer slowly right now that this could answer in five minutes?
