Research any topic across Reddit, X, YouTube, TikTok, Hacker News, and GitHub at once, then get one grounded brief ranked by what people actually engage with, not editorial picks.
The roster
What it does
Last30Days researches any topic or person across the places editors don't reach: Reddit, X, YouTube, TikTok, Hacker News, Polymarket, GitHub, and more, all searched in parallel. Instead of ranking by SEO, it scores what it finds by what real people actually engaged with, upvotes, likes, views, and prediction-market odds backed by money, then an agent judge synthesizes it into one grounded brief.
The result is the last-30-days truth a Google search misses: what someone is really working on this month, how a product is landing, what the community has already figured out. Ask for an HTML brief and it saves a self-contained file you can drop into Slack or Notion. Zero config to start; a setup wizard unlocks the gated sources in about 30 seconds.
