YouTube sentiment analysis starts in the comments.
A like ratio hides what viewers pushed back on. The comments show it. Taffy has already indexed 2,511 videos and their comments from 14 AI-builder channels, including Y Combinator, a16z and Greg Isenberg. The research reports what those audiences keep asking for. For the method, read how to analyze YouTube comments at scale.

"78% positive" doesn't help you make a better video.
What helps is the objection that repeats across a dozen comments, in the viewers' own words.
Taffy indexes the comments under every video in its library, alongside the transcript, so a reading stays tied to what was said on camera.

Common questions
Why not just look at the like ratio?
Like ratios are binary and lossy. A video can hold a 98% like ratio and still carry repeated objections in the comments. Those tell you what to fix on the next upload.
Does this run on my own videos?
No. Taffy covers a curated library of AI-builder channels.
Does Taffy score sentiment by topic?
No. Taffy indexes the comments and transcripts of library channels and answers questions with the episode and the minute. Pro exports the comments if you want to run your own scoring.
Can I track sentiment over time?
No. Taffy has no sentiment trend report. The research issues report what audiences asked for.
