Comment Automation
for YouTube Creators

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!

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.

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.

To get started, simply sign up with your Google account and link your YouTube channel. From there, you can start exploring the different features and configure your settings. Just login at /dashboard to get started.

Yes, we offer a free tier with limited features. You can upgrade to a paid plan at any time to unlock more features and higher limits.

CommentShark has a flexible pricing model to suit your needs. Current plans include:

• Free: 15 automated actions per month.
• CommentShark Plus ($9.99/mo): 300 automated actions per month plus AI features.

See the latest details on our pricing page.

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.

Use the Contact Sales form and share your team size, goals, and comment volume. We'll follow up with a tailored enterprise plan.

Currently, CommentShark supports one YouTube channel per account. However, you can invite team members to manage your channel without sharing YouTube credentials. If you need to manage multiple channels, you'll need separate CommentShark accounts for each.

Yes! You can invite team members to help manage your CommentShark account without sharing your YouTube credentials. Go to Settings → Team Access to invite people by email. You can assign roles like Admin (full access except billing), Editor (can reply and manage rules), or Viewer (read-only). Team members will receive an invite link at their email address.

You can permanently delete your account and all associated data from the Profile page in your dashboard. Scroll to the bottom to find the "Danger Zone". This action is irreversible.

Yes! You can choose between 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.

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. It learns from your previous replies to provide more natural responses, and you can provide more context to the AI to help it generate more accurate responses.

Comment actions execute after comments are synced from YouTube. Paid channels sync every hour, so the average response time is around 30 minutes. Free tier channels sync a few times per day, so actions may take several hours. This sync schedule ensures reliable delivery while managing API quota efficiently. You can monitor processed comments and see which ones matched your rules in the Activity tab.

The first time CommentShark loads your comments into our database (for example when you open the Comments page or a video for the first time after connecting), we do not run reply rules on that ingest. That prevents flooding old threads with automated replies. After that, new comments are eligible once they appear in a sync. On paid plans, background sync runs about hourly; opening Comments while logged in can also refresh from YouTube if your data is more than about a minute stale.

Yes! Beyond automatic replies, you can create rules that hold comments for review, reject them outright, or delete your own replies/comments. For comments left by other viewers, YouTube's API removes them via moderation actions rather than direct deletion. This is perfect for filtering spam, hate speech, or policy-violating content before it appears on your videos. Learn more about our YouTube comment moderation capabilities.

CommentShark uses the official YouTube API, so we only support actions YouTube actually exposes. That means CommentShark cannot:

• Like comments
• Heart comments
• Pin or unpin comments
• Edit comments written by other viewers
• Mark comments as spam via a dedicated spam action
• List or discover rejected comments from YouTube after they've been rejected
• Manage comments on videos where YouTube has disabled comments

The API also doesn't expose a direct pinned-status field, so pinned comment tooling has to work within that limitation. What CommentShark can do is reply, hold for review, reject, ban authors when YouTube allows it, delete your own comments, and bulk-edit the text of your existing pinned comments.

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.

Brand safety refers to protecting your brand's reputation by ensuring your content (and comments) don't appear alongside harmful, offensive, or inappropriate material. On YouTube, toxic comments, spam, and hate speech can damage brand perception—68% of buyers read comments before purchasing. CommentShark's moderation tools help keep your comment sections brand-safe 24/7.

Yes! CommentShark supports team collaboration for agencies and enterprise brands. You can invite team members to manage comments without sharing YouTube credentials. Features include role-based permissions (Admin, Editor, Viewer), approval workflows where team members review AI suggestions, and activity tracking to see who handled which comments.

CommentShark uses enterprise-grade security. We authenticate via OAuth 2.0 (we never see your password), use encrypted connections for all data, and comply with YouTube's official API policies. You can revoke access anytime via your Google Account settings.

The Bulk Pinned Comment Editor lets you scan your recent videos for pinned comments and update them all at once. You can use find & replace, apply a template with variables like {video_title} or {channel_name}, or edit each comment individually. It's perfect for keeping your pinned comments consistent across all your videos.

Sentiment analysis uses AI to score each comment on a scale from negative to positive. CommentShark automatically classifies every synced comment so you can see at a glance how your audience feels about each video, without reading thousands of comments manually.

Comment tags are automatic labels applied to each comment based on its content. Tags include categories like questions, praise, complaints, suggestions, and spam. They let you quickly filter and focus on the comments that matter most.

Sentiment scores are computed using AI embeddings and pre-trained anchor vectors. The system works well for general YouTube comment language. Individual comments can occasionally be misjudged (sarcasm is hard for any AI), but aggregate trends across a video are highly reliable.
