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?
