How to Research Any Topic Across Reddit, X, and TikTok in 90 Seconds

You know that feeling when you need to get smart on something fast, and suddenly you're 14 tabs deep in SEO articles from 2023? Reddit threads, X posts, TikTok takes, Hacker News debates. Each tab is a different platform. Each one takes forever. I used to spend hours every week doing exactly this just to keep up with AI news.

Then I found a viral Claude skill called last30days that searches a dozen platforms at once and only looks at the last 30 days. Real people. Real engagement. No stale blog posts. One prompt, about 90 seconds.

Why this matters

Google gives you what editors ranked. This gives you what people actually engaged with this month. Reddit upvotes, X likes, YouTube transcripts, TikTok views, and even Polymarket odds where people bet real money on what they think is true. That last one broke my brain. When thousands of dollars are on the line about whether something will happen, that's a stronger signal than any press release.

I used it three times this week alone: prepping for a meeting with a founder I'd never met, planning a trip to Alaska, and trying to figure out what's actually happening with the Anthropic IPO buzz. Each time, one prompt replaced what used to be an hour of tab-hopping.

Key insight: The best research isn't more sources. It's sources where people vote with their attention and their wallets, not their SEO budget.

What it actually does

Instead of searching Google, last30days searches Reddit, X, YouTube, TikTok, Instagram Reels, Hacker News, GitHub, Threads, Bluesky, Pinterest, Perplexity, and Polymarket. All at once. Only the last 30 days.

The scoring is what makes it different. Results get ranked by real signal: upvotes on Reddit, likes on tweets, views on TikTok, and actual money on Polymarket. A Reddit thread with 1,500 upvotes beats a blog post nobody read. A Polymarket market with real volume beats a pundit's guess.

You type a topic. A person, company, product, trip destination, anything. The skill figures out which handles, subreddits, and channels matter, searches them in parallel, and synthesizes everything into one brief with citations.

Install it (takes 2 minutes)

Pick the option that matches how you use Claude.

If you use Claude Code (recommended)

Open Claude Code and run:

/plugin marketplace add mvanhorn/last30days-skill
/plugin install last30days

The marketplace handles updates automatically. Reddit, Hacker News, Polymarket, and GitHub work immediately with zero config.

If you use Cursor, Codex, or another AI coding tool

Open your terminal and run:

npx skills add mvanhorn/last30days-skill -g

The -g flag installs it globally so it's available across all your projects. To target Cursor specifically:

npx skills add mvanhorn/last30days-skill -g -a cursor

If you use Claude on the web (claude.ai)

  1. Download the skill file from the latest release on GitHub
  2. Go to Settings → Capabilities → Skills
  3. Click the + button and upload the file

Make sure "Code execution and file creation" is enabled under Capabilities first. Skills won't run without it.

GitHub repo: github.com/mvanhorn/last30days-skill

Run your first search

Step 1: Type the slash command with your topic

In Claude Code or Cursor, type:

/last30days [your topic]

Examples:

/last30days Anthropic IPO
/last30days Alaska travel tips
/last30days [founder name]

The skill resolves the right people, subreddits, and channels before it searches. You don't need to know that r/ClaudeAI exists or which X account to check.

Step 2: Let it search in parallel

The skill hits every configured source at once. Reddit threads with top comments. X posts with engagement counts. YouTube transcripts from the last month. Polymarket odds. GitHub activity if you're researching a person or tool.

This takes about 60–90 seconds depending on how broad your topic is.

Step 3: Read the synthesized brief

You get one summary ranked by what real people engaged with. Citations included. Same story from Reddit, X, and YouTube gets merged into one cluster instead of three separate results.

Ask follow-up questions in the same session. The skill becomes your expert on that topic for the rest of the conversation.

Three ways I actually use it

Before a meeting with someone new

I had a call with a founder I'd never met. Instead of skimming a stale LinkedIn profile, I ran /last30days [her name]. In about 30 seconds I had her recent tweets, podcast appearances, Reddit mentions, and what the community was saying about her company. I walked in knowing what she'd been working on this month, not what her bio said two years ago.

Planning a trip

I was planning a trip to Alaska and didn't want affiliate blog posts from 2024. I ran /last30days Alaska travel June 2026 and got real reviews from people who went in the last few weeks. Which tours were worth it. What the weather was actually like. What Reddit travelers wished they'd known.

Cutting through headline noise

When the Anthropic IPO buzz started, every news site had a different take. I ran /last30days Anthropic IPO and went straight to what real people on X, Reddit, and Polymarket were saying. Not headlines. Actual sentiment and betting odds on what might happen.

Unlock more sources (optional)

Reddit, Hacker News, Polymarket, and GitHub work out of the box. Run /last30days once and a setup wizard walks you through unlocking more:

Reddit + HN + Polymarket + GitHubNothingFree
X / TwitterLog into x.com in any browserFree
YouTubebrew install yt-dlpFree
TikTok, Instagram, ThreadsScrapeCreators API key100 free credits, then pay-as-you-go
BlueskyApp password from bsky.appFree

You don't need all of these on day one. Start with the free sources and add more when you hit a topic that needs TikTok or Instagram signal.

Pro tips once you're rolling

Compare tools side by side

/last30days OpenClaw vs Claude Code

Runs one pass comparing both sides with live GitHub star counts and community takes. Used to take 12+ minutes. Now about 3.

Get a shareable HTML brief

/last30days Anthropic IPO --emit=html

Saves a clean, dark-mode HTML file you can drop into Slack, email, or Notion. No raw markdown leaks.

Say "eli5 on" for plain language

After any research run, say "eli5 on" and the synthesis rewrites in simpler language. Same data, same sources, just clearer.
