Mate this is fantastic! Much better than other, well known Chrome plugins I've used. Fastest way to respond to the most comments means more engagement with my subscribers over less time. Have my team using this and they're loving it.

Frequently Asked Questions

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?+
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 does the AI reply generation work?+
We use advanced AI models to analyze the sentiment and context of each comment. You can set custom instructions (e.g., "Be polite and grateful" or "Answer as a pirate") or use our smart templates. The AI generates a unique, personalized response that sounds like you.
Can I review replies before they are sent?+
Yes! You can choose between Fully Autonomous mode (replies are posted immediately) or Approval Required mode. In Approval Required mode, all AI-generated replies go to a queue where you can edit, approve, or reject them before they go live.
How much does it cost?+
CommentShark has a flexible pricing model to suit your needs:
  • Free: 30 comment actions per month.
  • Plus ($9.99/mo): 300 comment actions per month + AI features.
  • Pro ($19.99/mo): 1,500 comment actions per month + Priority Support.
What happens if I hit my monthly limit?+
If you reach your monthly limit for comment actions, the system will pause sending replies until your next billing cycle or until you upgrade your plan. You'll be notified so you never miss a beat. Manual replies are always unlimited.
How do I get it?+
CommentShark is a web app, so you can use it in your browser. It works best on desktop, but it also works on mobile. Just login at /dashboard to get started.
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.
Will my comments be classified as spam?+
No. Comments on YouTube are classified as spam by Youtube if they violate policy guidelines. You can read more about YouTube's spam policies and community guidelines.
Can CommentShark automatically moderate or delete comments?+
Yes! Beyond automatic replies, you can create rules that hold comments for review, reject them outright, or delete them permanently. This is perfect for filtering spam, hate speech, or policy-violating content before it appears on your videos. Combine AI classification with moderation to catch sophisticated spam that text matching filters miss.
Developed with YouTube, CommentShark uses the YouTube Data V3 API to provide you with the best YouTube comment management experience.
