Comparison
F5Bot is a free service that emails you whenever your keywords appear on Reddit, Hacker News, or Lobsters. It's the simplest possible monitoring tool — no dashboard, no AI, just email alerts.
You've outgrown email alerts and want a dashboard with AI reply drafting, intent classification, and quality gating across Reddit, X, Hacker News, and Indie Hackers.
You want completely free keyword alerts for Reddit and HN and are happy to manually track and respond to every mention via email.
Verdict: F5Bot is the starter tool you outgrow. It does one thing — email alerts — and does it for free. But when you start getting 20+ mentions a day and need to actually engage, Replii's dashboard, AI drafting, and intent classification make it possible to respond at scale without looking like a spammer.
