last30days just hit 6K stars — it researches anything across 10 platforms
A new Claude Code skill searches Reddit, X, YouTube, TikTok, and 6 other platforms in one command. 6,400 stars and 1,300 new stars today alone.
Imagine asking your AI one question and getting back a research briefing pulled from Reddit, X, YouTube, TikTok, Instagram, Bluesky, Hacker News, prediction markets, and the web — all cross-referenced and scored by relevance. That's what last30days does.
The tool just exploded on GitHub — hitting 6,400 stars with 1,300 new stars today alone. It works as a skill (a plugin) for Claude Code, letting you type one command and get a comprehensive research report on any topic from the last 30 days.
One Command, Ten Platforms, Real Answers
Here's what happens when you type /last30days prompting techniques for legal questions:
Phase 1 — Broad Discovery
The tool searches all 10 platforms simultaneously, scoring results by how recent they are, how many people engaged with them, and how relevant they are to your query.
Phase 2 — Smart Follow-Up
It extracts @handles from X posts, subreddit names from Reddit, and runs targeted follow-up searches — going deeper on the most promising leads.
Output
A structured briefing with source links, engagement metrics, cross-platform convergence flags ("this story appeared on Reddit AND Hacker News AND YouTube"), and real quotes from trending discussions.
Practical Examples Anyone Can Use
Market research: /last30days cursor vs windsurf — get side-by-side community sentiment

How to Set It Up
If you're using Claude Code, installation takes one command:
/plugin marketplace add mvanhorn/last30days-skill
/plugin install last30days@last30days-skillYou'll need at least one API key. The free tier gets you started:
• Hacker News + Polymarket — free, no API key needed
• Reddit + TikTok + Instagram — one ScrapeCreators key
• Web search — Brave Search offers 2,000 free queries/month
• X (Twitter) — uses your existing browser cookies or xAI API key
• YouTube — optional, requires yt-dlp (brew install yt-dlp)
Every research run automatically saves to ~/Documents/Last30Days/ as a markdown file — building a personal research library over time.
Who Benefits Most
Content creators and marketers can see what's actually trending before writing about it — not last week's trends, but what people are discussing right now.
Product managers can run competitive analysis in minutes instead of hours. The comparative mode (/last30 X vs Y) gives side-by-side breakdowns with community sentiment data.
Researchers and students get a starting point that's grounded in real, recent discussions with proper source attribution — not hallucinated references.
The tool runs in 2-8 minutes per query depending on depth. Use --quick for faster results or --deep for comprehensive 50-70 results per source.
