I was spending 45 minutes a day on Reddit hunting for startup ideas. Built something to fix that.

Every morning: open Reddit, HN, Product Hunt, X. Looking for problems worth building. Most days nothing. Occasionally something real buried in a comment thread I almost skipped.

After a few weeks I realised I was doing the same thing every day. Pattern matching for people describing friction, asking if something exists, complaining about a gap. Same job, same sources, every morning.

So I automated it.

Signal Scanner reads 9 sources daily and scores every startup opportunity it finds. Demand (are people actually asking for this?), market gap (does a good solution exist?), build effort (can a solo dev ship it in 2 weeks?).

1,041 signals so far. Updated daily. Free, no account needed to browse.

It's not trying to replace your judgment. It gives you the shortlist. You decide what's worth a closer look.

Would love to know what would make something like this actually useful in your workflow.
