F5Bot alternative
F5Bot tells you when a keyword appears. BeamSonar tells you when it matters.
BeamSonar is an AI-powered alternative to F5Bot for Reddit and Hacker News monitoring. Instead of string-matching keywords, an AI agent reads new posts around the clock, catches threads relevant to your product — even when nobody types your exact words — and pings you with a link, a quote, and a 0-100 intent score.

| Noise control | AI intent score 0-100 on every thread | Basic flags; AI filtering on Gold ($49.99) |

| Backlog | First sweep covers the last 30 days | Future mentions only |
| Lead tracking | Dashboard pipeline + feedback that tunes results | Email only |

When F5Bot is enough — and when it isn't
F5Bot is a great free tool if your brand name is distinctive and all you want is to know when someone types it. The gaps appear when you monitor a problem space: generic keywords flood you with false positives, and the buyers who describe your problem in their own words — “drowning in scheduling back-and-forth” instead of “Calendly alternative” — never trigger an alert at all.
BeamSonar was built for that second job: finding the people who need your product, whatever words they use, and only pinging you when a thread is worth replying to.
Common questions
How is BeamSonar different from F5Bot?
F5Bot emails you every post that contains your exact keyword — fast, but noisy, and it misses posts that describe your problem in other words. BeamSonar matches meaning: an AI agent reads new Reddit and Hacker News posts, catches threads relevant to your product even without your keyword, and scores each one 0-100 for buying intent, so alerts stay high-signal.
Do I have to pick keywords myself?
No. Paste your website URL and BeamSonar builds the intent profile automatically — keywords, competitor names, problem phrasings, and the subreddits where your buyers hang out. You can refine it afterward.
Is BeamSonar free like F5Bot?
Everything is free during early access, including daily email digests — no card required. After launch there will be a free plan alongside paid plans, with plenty of notice before anything changes.
Does BeamSonar cover the same sources?
BeamSonar monitors Reddit and Hacker News — the same core sources as F5Bot — with a first sweep that also shows you relevant threads from the last 30 days, something keyword alert tools cannot do.
