What is a YouTube comment analyzer?
A YouTube comment analyzer reads the comments on a video and turns them into something you can act on: how people feel, what they keep asking, which comments are spam, and who shows up most. Doing that by hand on an active video is impossible. A comment analyzer does it in seconds.
CommentShark's free tools each analyze a different slice of a comment section, and the dashboard brings full AI sentiment and intent analysis together with the ability to auto-reply and moderate. Paste a video URL above and start with any tool, no account needed.
What It Shows You
Everything hiding in a comment section, surfaced automatically
A comment analysis turns a wall of text into the handful of things worth acting on: the mood, the questions, the scams, and the people. Themes, timing, search, and export are free per video; sentiment and intent run on a connected channel.
Top Themes & Keywords
Surface the words, questions, and topics your audience keeps raising, so you know what to make next and what to address in a pinned comment.
Questions & Intent
Pull out the unanswered questions and buying-intent comments hiding in the thread, the ones worth a reply within the first hour.
Spam & Scam Signals
Spot the crypto bait, fake giveaways, and impersonator replies flooding your comments so you can hide them before your fans see them.
Comment Timing
Find the hours and weekdays your audience actually shows up in the comments, so you post and reply when engagement is highest.
Top Commenters
See who shows up most in your comment section: the superfans worth recognizing and the accounts worth watching.
Analyze a whole channel, not just one video
Some questions are channel-level rather than video-level. These tools take a channel handle instead of a video URL.
- Comment Audit Audit a whole channel: unanswered questions, high-intent conversations, and reply rate.
- First Comment Finder See who left the first comment on any video.
Sentiment across every video, not just the one you pasted, is a connected-channel feature. Want that plus the ability to auto-reply and moderate? See how CommentShark manages your comments, or read what a moderation workflow looks like once the analysis is done.

How does it work?
CommentShark connects to your YouTube channel via the official API. You set up "Rules" that match specific text, use AI classification, or text matching patterns. When a new comment matches a rule, CommentShark can automatically reply, moderate (hold for review or reject), or delete the comment—running 24/7 in the background. You choose whether actions happen automatically or require your approval.
Is there a free tier?

When you outgrow the cap, upgrade from the Billing page to Plus, Pro, or Premium for higher limits and AI comment classification.
