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.
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.
How do I get started?
+
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.
Is there a free trial?
+
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.
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.
How do I contact sales for enterprise plans?
+
Use the Contact Sales form and share your team size, goals, and comment volume. We'll follow up with a tailored enterprise plan.
Does CommentShark support multiple channels?
+
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.
Can I invite team members to manage my CommentShark?
+
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.
How do I delete my account?
+
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.
Can I review replies before they are sent?
+
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.
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. 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.
How long does it take for automations to reply to comments?
+
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.
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. Learn more about our YouTube comment moderation capabilities.
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.
What is brand safety and why does it matter for YouTube?
+
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.
Does CommentShark support teams and agencies?
+
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.
Is CommentShark secure for enterprise use?
+
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.
What is the Bulk Pinned Comment Editor?
+
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.
Developed with YouTube, CommentShark uses the YouTube Data V3 API to provide you with the best YouTube comment management experience.
