YouTube Comment Finder

Our YouTube Comment Finder is a simple, fast way to search comments on any public YouTube video or Short. Paste a video URL, type a keyword, phrase, or @mention, and instantly see every matching comment — including who left it and when.

How do I find a YouTube comment?

To find a YouTube comment, paste any YouTube video URL and search by keyword. Author names and timestamps appear in the results so you can scan who said what.

How to Search YouTube Comments by Keyword

YouTube doesn't offer a built-in way to search comments on someone else's video. YouTube Studio lets you search comments on your own channel and videos, but not on videos owned by other creators.

The YouTube Comment Finder works on any public video or Short. Paste the video URL and search by keyword to find every matching comment — including @mentions of a specific user.

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.
How is CommentShark different from YouTube Studio's built-in tools?
+
YouTube Studio lets you moderate comments manually — one at a time. CommentShark adds automation on top: keyword rules, AI classification, auto-replies, scheduled moderation, and bulk actions across all your videos. Think of it as YouTube Studio's comment tools on autopilot.
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.

Why Use Our YouTube Comment Finder?

Our YouTube Comment Finder is designed for one job: finding the exact comment you need, fast. Unlike YouTube Studio, this works on any public video — not just videos you own. Whether you're a content creator tracking down a viewer's feedback, a marketer auditing brand mentions, or a researcher looking at audience sentiment, it surfaces what you're looking for in seconds.

First YouTube Comment Finder

Want to find the first comment on a YouTube video? YouTube doesn't allow you to sort comments by oldest, making it nearly impossible to find the very first comment on popular videos. Try our dedicated YouTube First Comment Finder tool to instantly discover the oldest comment on any video!

CommentShark also gives you the ability to search and order your YouTube comments, and gives you the ability to filter comments by sentiment, date, and more! Sign up for free to use our advanced features.
