See what the comment section actually says
Paste a YouTube link. Commenterra collects the public comments, groups them by topic, and lays them out as a map you can read, filter and search.

The whole discussion on one screen
Every comment becomes a rectangle. Bigger means longer, colour means sentiment, and hovering or clicking one opens the exact comment and its replies.
Raw
Every public comment, in the order YouTube hands them over. On a busy video that is thousands of lines nobody reads to the end.
Structure
Each comment is scored for what it actually says and grouped with the ones making the same point. Topics become sectors; a comment becomes a rectangle sized by how much was written.
Insight
Open a rectangle and you get the exact comment, its replies, and the moment in the video it is about.
Why read the map instead of the comments
- Thousands of comments, one picture
- A busy video has more comments than anyone reads. The map shows every collected comment at once, sized by how much was written.
- Popular is not the same as important
- Sorting by likes surfaces jokes. Commenterra scores each comment for how much it actually says, and puts those first.
- Find the argument, not the noise
- Filter to negative comments on one topic, or to the ones people replied to, and read only those.
What you get
Topic map
Comments grouped into named topics and drawn as a zoomable, pannable map.
Importance scores
Every comment scored for substance, with the highest first and a bar showing the score.
Filters
Narrow by topic, sentiment, date, likes and reply count, or to a single commenter.
Video summary
A written summary of the video with clickable timecodes that seek the player.
Discussion heatmap
See which parts of the video the comments are actually about.
Threads and saved comments
Open any comment with its replies, save the ones you want, and export them as text.
What we do with the comments
Four steps, in this order, every time.
Collect
Public comments on the video are collected together with their replies.
Score
Each comment is scored for how much it actually says. Likes don't count towards the score.
Group
The comments with the highest importance are drawn on the map and grouped into up to twelve named topics.
Summarise
The video's public captions become a written summary, and comments are matched to the moments they discuss.
A busy comment section is sampled rather than read end to end, and sentiment and topics are a model's readings, so they can be wrong.

- Can I read the analysis in my language?

- Who can see my analysis?
