Every reason not to, already handled

  • I don't trust AI near my audience.

    Approve everything first

    Switch any rule to hold its replies, then approve or edit each one, so nothing ever carries your name until you have read it.

  • I really don't trust AI.

    Then don't use it

    Keyword rules, replies you wrote. No AI picks the match, no AI writes the words, so the wording is yours before a single comment lands.

  • I don't want it replying for me at all.

    It doesn't have to reply

    Point the same rule at moderate or delete, or have it just email you when something matches, so it only ever does the part you actually want.

  • Honestly, I like replying by hand.

    Reply by hand, harder

    Save your own autocompletes, then start typing and the rest of the reply appears with the commenter's name already in it, so it stays personal and stops eating your evening.

  • My backlog is thousands deep.

    Replay over old commentsPaid plans

    Point your rules at one video, or at everything since a date you pick, so a pile you were never going to clear by hand finally gets handled.

  • How do I know a rule won't go rogue?

    Test it before it's live

    Easily test a rule or pause it anytime!

You have the final say

Nothing goes out under your name until you say so

Switch a rule to hold its replies and every draft lands in a review queue. Approve, tweak, or reject in one click, and let it run on its own only once it has earned it.

Approve in the app

Skim the queue on the dashboard and clear it in a tap.

Approve from your inbox

Turn on Email to Approve and act on each draft right from the email.

Let your team approve

Invite a manager or VA with their own login. They clear the queue without ever touching your YouTube credentials.

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, 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.
