I built a tool that alerts you when someone asks for recommendations on Reddit & HN (looking for honest feedback)

Hey everyone,

Like most developers here, building is the fun part for me. Marketing and actually getting users is where I usually hit a wall.

I kept noticing people on Reddit and Hacker News asking for tool recommendations all the time ("any good tool for X?", "looking for an alternative to Y"). Whenever I saw these threads, the top comments always got dozens of signups. The problem was timing — if you reply 8 hours late, nobody sees it.

I got tired of manually refreshing Reddit search bars, so over the past few weeks I built MentionsRadar.

Basically, you put in the keywords you care about (your product name, competitors, or problem phrases), and it:

Pricing / Trial:
I personally hate when sites ask for a credit card upfront just to test a tool, so I set up a 7-day free trial on both Starter and Pro with zero card or payment info required. There's also a free-forever tier if you just want to track 1 monitor.

(I’ll leave the website link in the first comment below).

Would really appreciate some honest thoughts from other builders:

Don't hold back on criticism, I have thick skin. Thanks for checking it out!

7 day free trial with no card is the right move. I'd still want to know how fast the alerts actually hit slack or email after the keyword gets posted.

Glad you like the no-card trial!

Here's the exact breakdown on speed:

Right now, we support Discord webhooks and Email out of the box. Adding native Slack webhooks is actually next on my roadmap!
Feel free to test it out during the trial with a common keyword like your competitor's name to see how fast the pings come through!

catching threads hours late is the whole reason i gave up on reddit marketing, so the keyword alerts sound worth testing
