Know the moment you’re mentioned online.

Keyword Radar pings you the instant your keywords show up on Reddit, Hacker News, Lobsters — or any feed you paste in. Email, Slack, or webhook. 100% free.

  • ✓ Posts and comments, not just titles
  • ✓ Slack & webhook delivery, not only email
  • ✓ Bring your own RSS / Atom / JSON feed
  • ✓ Manage everything from Claude via MCP

How it works

1. Add keywords

Your brand, product, name, competitors — whatever you want to hear about.

2. We watch the firehose

Every minute we scan new Reddit posts & comments, Hacker News, Lobsters, and your custom feeds.

3. You get pinged

A match lands in your inbox, Slack, or webhook within minutes — with a link straight to it.
