Keep up with your YouTube commentseven when you can’t

Yes — every account starts on the Free plan with no card required. It includes AI-generated replies, keyword and regex matching, and AI comment classification, with 3 rules and 20 comment actions per month so you can try the workflow on real comments before paying. Free channels are checked for new comments every 2 hours. If 14 days pass with no sign-in and nothing done by your rules, checks pause until you next sign in or edit or test a rule. When you need more capacity, upgrade from the Billing page.

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.

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. Choose Review in the waiting-actions banner on the Rules page when a draft is ready, or open pending approvals under the notification bell. To keep the queue short, new drafts pause while 5 are waiting (25 once you have reviewed one). Paused matches are not charged; review some drafts and drafting resumes.

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. AI suggestions and automated replies also use available synced messages from the same comment thread to understand the conversation. Longer threads keep the opening comment and recent exchanges. This conversation context is separate from the past replies used to learn your voice.

If you reach your monthly limit for comment actions, CommentShark pauses running your rules until your next billing cycle. You'll be notified, so you never find out by accident. From there you have two ways to start again immediately: move up a plan, or buy a one-time action pack that tops up this account without changing your plan.
