You can't tell if a video bombed until the metrics catch up
View count and watch time lag the comment thread by hours or days. Sentiment is the leading indicator that says "this one didn't land" while you can still respond.

Why It Matters
Why YouTube creators watch sentiment, not just views
View count tells you who showed up. Sentiment tells you what they thought. Here is what reading the comments by hand misses.
A quiet controversy looks the same as nothing happening
If you only watch likes vs dislikes, you miss the cluster of negative comments forming under one video. Sentiment scoring surfaces the cluster before it goes viral the wrong way.
Real questions get buried under praise
Genuine “how do I…” comments drown in “great video!” replies. Tag filtering pulls the questions to the top so you can answer them or fold them into the next script.
You're guessing which video format your audience prefers
Per-video sentiment breakdowns make it explicit. Compare longform vs shorts, interview vs solo, talking-head vs voiceover, and see which one your audience actually liked.
What are YouTube Sentiment Insights?
Sentiment Insights score every comment on your channel as positive, negative, or neutral, then roll those scores up so you can see the mood of your audience at a glance: per video, per week, or across your whole channel.
AI-powered comment tagging surfaces recurring themes, and anomaly alerts ping you when the sentiment on a video moves outside its normal range, so you find the problem (or the win) while it still matters.

Five views that turn raw comments into audience signal
From sentiment timelines and per-video breakdowns to AI comment tagging and anomaly alerts. Every primitive you need to read the mood of your channel without scrolling threads.
Sentiment Timeline
Visualise how your audience mood shifts over days, weeks, and months. Spot trends early and understand how your content impacts viewer sentiment.
Per-Video Breakdown
See sentiment scores for each video individually. Compare how different topics, formats, or styles resonate with your audience.
AI Comment Tagging
Every comment is automatically tagged by topic and intent: questions, praise, complaints, feature requests, and more. No manual labelling needed.
Anomaly Alerts
Get notified when sentiment spikes or drops unexpectedly. Catch controversies, viral moments, or community issues before they escalate.
Tag Filtering
Filter your insights by any combination of tags. Drill into just the questions, just the negative feedback, or any slice of your comment data.

Built For
Teams using YouTube sentiment as a leading indicator
Audience mood moves before metrics do. These are the people who watch it on purpose.
Solo Creators
Read your audience without scrolling threads. Catch the moment a video breaks against your usual sentiment line and learn what landed (or didn't).
Marketing Teams
Measure campaign reception against baseline. See if a launch trailer is shifting audience mood positive or negative, before the metrics roll up to leadership.
Educators & Course Creators
Surface real student questions and complaints buried in praise. Tag filtering pulls out the “I'm stuck on…” comments that need a follow-up video.
Product Launches
Monitor reception on launch day and the week after. Anomaly alerts flag a sentiment dip before it shows up in a refund spike or a churn metric.

What is CommentShark?+
What is CommentShark?
CommentShark is a web app that helps you scale engagement with your YouTube audience. It's the ultimate YouTube comment management tool. CommentShark allows you to quickly respond to comments, reply to multiple comments at once, use the help of AI to generate replies, template repetitive responses, search and filter your comments, find your top commenters, see your history with them, and much more!
How does it work?+
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.
How is CommentShark different from YouTube Studio's built-in tools?+
How is CommentShark different from YouTube Studio's built-in tools?
YouTube Studio lets you moderate comments manually — one at a time. CommentShark adds automation on top: keyword rules, AI classification, auto-replies, scheduled moderation, and bulk actions across all your videos. Think of it as YouTube Studio's comment tools on autopilot.
Is it safe?+
Is it safe?
Absolutely. We use official YouTube APIs and OAuth 2.0 for secure authentication. We only request the permissions necessary to manage your comments. We don't store your password, and you can revoke access at any time via your Google Account settings. See more at our Terms of Service.
