Reddit keyword alerts, as a clean RSS feed
Reddit search matches words, not meaning. A keyword alert for "notion" returns posts about the product and posts about free will. A Redditrss topic feed removes the second kind before it reaches you.
How a topic feed works
- You enter a product, brand or topic.
- Redditrss runs a keyword search across Reddit.
- An AI reads each result and keeps only posts that are really about your topic.
- You get a private feed link, redditrss.com/f/<token>.xml, refreshed about every 30 minutes.
Where the feed can go
- An RSS reader: Feedly, Inoreader, NetNewsWire, FreshRSS.
- Chat: Slack or Discord.
- Automation: n8n, Zapier, Make.
What teams track
- Mentions of your product, and questions people ask about it.
- Competitor names, to see why people switch.
- Problem phrases in your market, to find people who need what you sell.
