Hey Product Hunt!
I'm Adrián, and I built LikePulse because I kept wondering: why can't I see WHERE people actually react in a YouTube video?
Not just view counts — the exact second the audience exploded.
So I built it. LikePulse analyzes public comments, extracts timestamps, and builds a real-time heatmap of audience reaction on any YouTube video. Pair that with Most Replayed data from YouTube itself and you get a dual-signal picture of where the video actually worked.
On top of that: Claude Haiku reads the comments and tells you WHY each moment resonated — what emotion drove it, what the creator could improve.
Free. No account needed. No data collected.
One note: Chrome may show a "proceed with caution" warning — that's normal for new extensions without user history yet. The code is clean and fully auditable.
Would love your honest feedback — what's missing? What would make this a must-have for you?
Really interesting concept. Most analytics tools show views and retention, but LikePulse focuses on audience reaction moments, which feels much more actionable for creators and marketers. The engagement heatmap combined with AI explanations is a very smart touch. Congrats on the Product Hunt launch
the product detection feature is the one that feels slightly out of place with the rest. heatmaps and key moments are clearly for creators and researchers. amazon product detection feels like a different user entirely, affiliate marketers or brand analysts. are those actually the same person in your head or did that feature come from a different use case you're testing. curious because it changes who you're building for pretty significantly
knowing WHERE in the video people react is way more useful than just total view count. this is basically a free focus group for every video you publish
Really like the framing of overlaying comment spikes with Most Replayed — the two signals say different things and the gap between them is where the interesting stuff lives. I run the Mod3Loop YouTube channel on financial modeling, and the moments people comment on are almost never the ones I'd predict from watch retention alone. Tools that surface that mismatch quickly would change how I edit. Following.
