Show HN: TopicRadar – Track trending topics across HN, GitHub, ArXiv, and more

14•MickolasJae•10h ago
Hey HN! I built TopicRadar to solve a problem I had with staying on top of what's trending in AI/ML without checking 7+ sites daily.

https://apify.com/mick-johnson/topic-radar

What it does: - Aggregates from HackerNews, GitHub, arXiv, StackOverflow, Lobste.rs, Papers with Code, and Semantic Scholar - One-click presets: "Trending: AI & ML", "Trending: Startups", "Trending: Developer Tools" - Or track custom topics (e.g., "rust async", "transformer models") - Gets 150-175 results in under 5 minutes

Built for the Apify $1M Challenge. It's free to try – just hit "Try for free" and use the default "AI & ML" preset.

Would love feedback on what sources to add next or features you'd find useful!

Crazy how me and my brother had the same idea 7-8 months ago when claude was hosting their own challenge and we were gonna use Apify or build on top of apify itself something eerily similar to this

Though we wanted to include reddit & twitter as well. Reddit's got a recent database and being able to query it with hourly updates iirc so you can probably query this as well or use that as well

Not sure about twitter but twitter does seem to be the most valauable insight in AI/ML right now (considering that I see tweets of qwen guys or similar AI teams on r/locallama whose link might be even on hackernews haha!)

Personally I don't use twitter and follow HN/reddit as such for that sometimes especially reddit's r/localllama

Also my brother wanted to expand this to something general ie people can search for anything on reddit/twitter or get updates if people reference something iirc about anything not just particularly AI/ML

Anyways coding challenges are great and so good luck!

Yeah, honestly it's just consolidation of data. I don't want to have to go to 8 different sources and try and click through all of that nonsense. It's really because I'm lazy.
