Protect Your Brand.
Scale Your Engagement.

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:

• 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.

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.

Sign in with your YouTube account, create auto reply rules with text match or AI triggers, choose a response template or AI-generated reply, and activate the rule so CommentShark can post for you 24/7.

Auto reply rules combine a match condition, a response, and a posting mode. CommentShark monitors incoming comments, checks them against your rule logic, and either posts immediately or queues the reply for approval based on your settings.

Yes. You can create reusable templates with variables, add AI instructions for tone or talking points, and tailor responses for different scenarios so every automated comment still sounds on brand.

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 take at most 1 hour to execute because comments need to be synced from YouTube first. Paid channels sync every hour, so the average response time is around 30 minutes. 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.

Yes! Use the "Test all rules" button on the auto-reply rules page. Simply paste sample comment text to instantly see which rules match, why they matched, and what response would be generated, without posting anything to YouTube. This is the fastest way to verify your rule logic without waiting for actual comments.

No. Automation rules are forward-looking only—they only apply to new comments that arrive after you enable the rule. This prevents accidentally spamming replies on old videos or comments you've already handled manually. If you enable a rule today, it will only process comments posted from that point forward.

The Activity tab shows all comments that CommentShark has processed, including which ones matched your rules and which were skipped. You can see exactly why a comment matched (or didn't match), which rule triggered, and what action was taken. This is helpful for debugging rules and understanding your automation's behavior.

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.

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.

If a moderator's access is revoked or their token expires, CommentShark automatically disables the affected rules and notifies both the moderator and channel owner via email. This prevents failed actions from piling up.

Posting as yourself requires YouTube write permissions and shows replies from your channel. Reply Assistant mode uses CommentShark's assistant account, which doesn't require write access but requires Community posts to be enabled on your channel. This is ideal for security-conscious creators who prefer not to grant third-party write permissions.

No. CommentShark automatically ignores comments made by the channel owner and comments you've already replied to. This prevents infinite reply loops and duplicate responses. Rules also only apply to new comments received after the rule is enabled (they are forward-looking).

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.

CommentShark uses AI-powered rules to automatically detect and handle problematic comments. You can create rules that:

• Hold for review: Flag suspicious comments for manual approval before they stay visible.
• Reject automatically: Immediately hide spam, hate speech, or policy violations.
• Delete permanently: Remove harmful content entirely.

Rules can use text patterns or AI classification to match comments.

CommentShark can detect and moderate spam (promotional content, scam links), hate speech and toxic language, competitor mentions, off-topic comments, profanity, and any custom criteria you define. Our AI classification understands context—so genuine criticism is distinguished from actual brand attacks.

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 syncs comments regularly throughout the day. For paid channels, comments are typically processed within an hour of being posted. Moderation actions (hold, reject, delete) execute immediately once a comment is matched by your rules.

Yes. CommentShark offers an approval queue where flagged comments go for human review before action is taken. This is perfect for brands that want AI assistance but require human oversight. You can approve, reject, or edit suggested actions before they go live.

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.

Yes! For agencies, brands, and enterprise teams with custom requirements, we offer tailored pricing and features. Contact us at enterprise@commentshark.com to discuss your needs.

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.
