How to find comments by a user on one YouTube video

To find comments by a user on one public YouTube video, search the video's thread by the author's channel name. YouTube does not show another user's complete comment history across the platform. For one video, you can use browser Find on comments already loaded on the page, or use the YouTube comment search tool to scan available comments and replies.

Browser search (Page find):

1. Open the YouTube video in your desktop browser.
2. Scroll down until comments load fully.
3. Press Ctrl + F (Windows) or Cmd + F (Mac) and type the user's @handle.

Using a tool to scan the available comments

Ctrl+F only searches what the browser has already rendered, so on a video with four thousand comments it is searching the forty you happen to have scrolled past.

The comment search here scans the available set: paste the video link, leave the keyword box empty, and put the channel name in the author box. It reads comments through the official API rather than the rendered page, includes replies in the scanned set, and links each result straight to YouTube. The free tier scans the most recent 500 comments; your own API key raises that ceiling to 1,000. The tool tells you when it has reached the limit, so it does not imply that older comments were checked.

Browser extensions exist for this too. They need access to your YouTube pages to work, which is worth weighing before installing one.

How to search YouTube comments for keywords

YouTube does not offer viewers a search box for an entire comment thread. Browser Find only checks comments already loaded on the page, so it can miss most of a busy video's discussion.

1. Open the YouTube comment search tool.
2. Paste the public YouTube video URL.
3. Enter the keyword, phrase, channel name or @handle you want to find.
4. Run the search and open any matching result on YouTube.

The free search scans up to 500 recent comments and replies. A personal YouTube Data API key raises the limit to 1,000. It searches one public video at a time; it cannot search every comment across YouTube or recover deleted comments.

Why search comments by a specific user?

Whether you are a channel owner managing community discussions or a viewer trying to track down a link you previously commented on, finding all comments from a specific user is a frequent challenge.

Common scenarios include:

• Channel Owners Identifying Superfans: Finding how often a dedicated follower has commented to reward them or give them moderator status.
• Moderation & Spam Investigation: Checking if a problematic commenter has posted scam links across multiple videos.
• Giveaway Verification: Confirming if a contest winner actually left a valid entry comment.
• Personal Review: Viewers wanting to edit or delete their own past comments.

Use the method below that matches your situation; no method can reveal another user's complete comment history across YouTube.

Method 1: channel owners, searching by user in YouTube Studio

If you own the channel, YouTube Studio makes it easy to filter comment feeds by username or channel handle:

[ YouTube Studio ] ➔ [ Comments Tab ] ➔ [ Filter Icon ] ➔ Select: "Search" ➔ Type Username or @Handle

Step-by-step for creators:

1. Navigate to YouTube Studio (studio.youtube.com).
2. Click Comments on the left menu.
3. Click the Filter icon at the top of the comment table.
4. Select Search from the dropdown menu.
5. Type the user's exact @handle or channel display name.

Studio returns that person's comments across your channel's videos. Useful for spotting a regular you want to make a moderator, for checking whether a giveaway winner actually entered, and for seeing whether an account dropping links has done it more than once.

One caveat: this searches the comment feed Studio has, which is your channel. It tells you nothing about what that person has said anywhere else, and no setting changes that.

Method 2: viewers, how to view your own past YouTube comments (Comment history)

If you are a viewer looking to review, edit, or delete comments you have posted across YouTube:

1. Go to YouTube (youtube.com) and ensure you are logged into your Google account.
2. Click History in the left sidebar menu.
3. On the right side under Manage All History, click Comments (or visit myactivity.google.com/page/youtube_comments).
4. Google will display a complete, timestamped history of every comment you have ever made on YouTube, with direct links to view or delete them.

Managing superfans & problematic users with ReplyTide

Managing interactions with frequent commenters can become time-consuming as your channel grows into tens of thousands of subscribers.

By using ReplyTide, creators can automate engagement while maintaining high community standards:

• Requested resource access: Give superfans the checklist or template from the next eligible automated reply, without making you paste the link manually.
• Narrow triggers: because it fires only on an exact word you announced, accounts leaving generic praise or spam never trigger a delivery.

If this is about a problem commenter

Finding their comments is the first half. The second half is Studio's moderation settings, and the two that matter are Hide user from channel, which makes everything they have said invisible to everyone but them, and the blocked words list, which catches the pattern rather than the person. Both are free, both sit under Settings then Community moderation, and the full setup takes about five minutes.

Hiding a user is silent by design. They are not told, and their comments still look normal to them. That is what makes it effective, and what makes it worth using deliberately rather than in irritation.

Common questions

Can I see all comments a user has made on other people's YouTube channels?

No. YouTube does not provide a public profile feature that lists all comments made by a user across third-party channels for privacy and anti-harassment reasons.

What happens if I hide a user from my channel?

If you click Hide user from channel in YouTube Studio, that user's past and future comments will remain visible only to them. To everyone else on YouTube (including you), their comments become completely invisible.

Can deleted YouTube comments be recovered?

No. There is no bin and no restore option, for either the author or the channel owner. If you need a record of a comment thread, export it before anything changes.
