Frequently Asked Questions

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.
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.
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.
