Sentiment by topic. Not by thumbs.
YouTube comment sentiment analysis, by topic instead of by thumbs. Taffy reads every comment and ties reactions to the specific topics discussed. Which segments worked and which fell flat. Which deserve a follow-up upload. For the method behind it, read how to analyze YouTube comments at scale.
Creator Club indexes your channel and runs Video Postmortem weekly. Library indexes featured channels for research.
"78% positive" doesn't help you make a better video.
"The Zone 2 segment drew positive sentiment with three repeated callbacks; the supplement segment drew skepticism and the same objection across 12 comments" does.
Taffy ties viewer reactions to the specific moments, ideas and claims in the video. That's how sentiment becomes actionable on the next upload, not just a number in a dashboard.
What you see
Sentiment broken down by topic, segment and recurring reaction patterns — not a single dial.
Topic-level sentiment
For every topic mentioned in the video, the sentiment of viewer reactions tied to that topic. Praise on Zone 2. Skepticism on a specific supplement claim. Confusion on a methodology.
Recurring reactions
Reactions clustered by theme, not just polarity. "Loved the directness." "Wanted more on the protocol." "Pushed back on the dose."
Segment hot spots
Timestamped clusters where comments gather. The segments viewers quoted and called back to.
Cross-video trend
How sentiment on a recurring topic has shifted over your last 10 uploads. Are viewers warming up, cooling off or asking for new angles?
Whose audience are you reading?

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. Topic-level sentiment surfaces that.
Does this run on my own videos?
Creator Club, yes — we index your channel and run Video Postmortem on every upload. Library, no — the Library is for sentiment on the featured channels Taffy already indexes.
How are topics linked to sentiment?
We extract topics from the transcript, then match comments to the topics they reference. Each topic gets its own sentiment slice, with example comments backing the score.
Can I track sentiment over time?
Yes. Creator Club tracks trends across your last 10 uploads, or all of them. You see when a topic tires and when a new angle breaks through.
