Search YouTube comments

Find a comment by what it says or who wrote it, then jump straight to it on YouTube. Ctrl+F only searches the comments already loaded on screen — this searches the scanned set of up to 500 recent comments, or up to 1,000 with your own API key.

Why YouTube itself cannot do this

YouTube loads comments a page at a time as you scroll. Ctrl+F searches only 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. There is no comment search in the interface, and there has not been one for years.

This tool reads the comments through the official API and searches the whole scanned batch at once, then hands you a link that opens the matching comment in place.

How the matching works

Stated plainly, because a search you cannot reason about is a search you cannot trust when it returns nothing.

• Word or phrase is a plain substring match, ignoring case. Searching tripod finds Tripod and tripods.
• Match whole words only switches to word-boundary matching, so code stops matching barcode and codes. It relies on spaces and punctuation, so leave it off for Japanese or Chinese comments, where there are no word gaps for it to find.
• Author is also a case-insensitive substring, matched against the name shown beside the comment. Part of a name is enough.
• Both boxes together narrow rather than widen: a comment must match the word and the author to appear.
• Replies are searched unless you untick the box, and a matching reply is returned like any other comment.

Every result carries a link of the form youtube.com/watch?v=<video>&lc=<comment>, which is the URL that opens one specific comment in place on YouTube rather than dropping you at the top of the thread.

What the CSV contains

Four columns, in this order: author, text, published_at and permalink. UTF-8 with a byte-order mark so CJK text and emoji survive Excel, every field quoted, and a leading =, +, - or @ prefixed with an apostrophe so a comment cannot be opened as a spreadsheet formula. The file is named youtube-comment-search-<video id>.csv.

It is deliberately narrower than the comment exporter, which gives you nine columns including comment ids, like counts and the reply relationship. If you want to analyse a comment section, export it. This file is for the handful of comments you were looking for.

A worked example

Sample data, not a real video. Searching a product review for discount, two matches, downloaded:

author,text,published_at,permalink
"Priya N","Is the discount code still live?","2026-08-14T07:21:44Z","https://www.youtube.com/watch?v=abc123XYZ_-&lc=UgxAbC1"
"Sam","discount ended last week I think","2026-08-14T11:05:02Z","https://www.youtube.com/watch?v=abc123XYZ_-&lc=UgxAbC1.7"

The second row is a reply. The search result list does not label replies separately — if you need that distinction in a file, the exporter's is_reply and parent_id columns are the place to get it.

What people search for

• The comment you remember but cannot find — someone posted a link, a code, a correction, and it is now two thousand comments deep.
• Everything one person said — leave the keyword blank and put their channel name in the author box.
• Whether a question was already asked — before you answer the same thing for the twentieth time.
• Giveaway entries containing a required word — though the winner picker does that end to end.

The limits, in numbers

Comments are read newest first, so a scan that stops at the ceiling has the most recent 500, not a random 500 — and the tool says so in the summary line rather than implying it searched everything. The scan counts replies as comments, so on a thread-heavy video 500 scanned covers fewer distinct top-level comments than you would guess.

If more than 200 comments match, the first 200 are shown and exported and the summary says so. That is usually a sign the search term is too common rather than a limit worth working around: narrow the term, or export the whole comment section and filter it in a spreadsheet.

How it compares to the other comment finders

Figures read from each tool's own page on 24 August 2026, and they will drift.

The honest reading of that table is that the ceiling here is the lowest of the three tools. CommentShark's cited signed-in ceiling is 2,000 comments, while Hadzy says it loads every comment and reply; those are vendor claims, not a guarantee for a particular video. Do not assume either tool will reach a specific comment at a given depth without checking the current product and thread. What you get here is a scan that is explicit about where it stopped, a match list with a per-comment permalink, and a CSV without an account.

For a full-channel search, none of these will do it: that needs an authorised connection to the channel rather than a public lookup.

What to try before reaching for a tool

Three things work without any tool at all, and it is worth knowing where each one stops.

Scroll, then Ctrl+F. If the comment is recent and the video is quiet, loading a few screens and searching the page will find it. This fails silently on busy videos: the browser has only rendered what you scrolled past, so a search that finds nothing is indistinguishable from a comment that does not exist.

Sort by newest first. The default is Top comments, which is a ranking rather than a chronology. If you are looking for something posted in the last day, switching the sort is often the whole answer.

Check your notifications. If the comment was a reply to you, or mentioned your channel, it is in your notification history — which is searchable in a way the comment section is not.

Those cover the easy cases. What they cannot do is search a thread you never scrolled, find every comment by one person across a long video, or tell you reliably that something is not there.

What this tool cannot do

Worth stating plainly, because the limits are structural rather than a paywall.

• It cannot search a whole channel. The API works per video. Searching everything you have ever published needs an authorised connection to the channel, not a public lookup.
• It cannot search private or unlisted videos. The API only returns comments on public videos, whoever is asking.
• It cannot find deleted or held comments. A comment held for review by YouTube's spam filter is invisible to the API, which is why a comment someone insists they posted can be genuinely unfindable. The causes of missing comments covers that case.
• It cannot search comments you left on other people's videos. That history lives in your Google account, not in any video's comment thread.

Common questions

Can you search YouTube comments?

Not on YouTube itself. The site has no comment search, and Ctrl+F only finds text the browser has already loaded, which is the handful of comments you have scrolled past. This tool reads up to 500 recent comments by default, or up to 1,000 with your own API key, and searches the scanned set at once.

How do I find all comments by one person on a video?

Leave the keyword box empty and put their channel name in the author box. Every matching comment in the scanned set is returned, replies included; the scan covers up to 500 recent comments by default, or 1,000 with your own API key.

Why does Ctrl+F not work on YouTube comments?

YouTube loads comments a page at a time as you scroll. Ctrl+F searches only what is currently in the page, so anything not yet loaded is invisible to it. Scrolling to the bottom of a busy video first is impractical.

Can I jump straight to a comment I find?

Yes. Every result carries a direct link that opens that specific comment in place on YouTube.

Does searching comments need a YouTube API key?

No. The tool scans the most recent 500 comments free with no signup. Adding your own YouTube Data API key raises that to 1,000, which matters on videos with very large comment sections.

Does the search cover replies?

Yes, unless you untick the box. Replies are where answers usually hide. They are searched alongside top-level comments, a matching reply is returned like any other result, and they count towards the number of comments scanned.

Can I search the comments on a YouTube Short?

Yes. A /shorts/ link is handled the same way as a watch page, because a Short is an ordinary video as far as the API is concerned. Live and embed URLs work too, as does a bare video id.

How many results can the search return?

Up to 200 matches are shown and exported. If more than 200 comments match, the summary line says so. That usually means the search term is too common rather than that the limit is in the way.

What columns does the downloaded CSV have?

Four, in this order: author, text, published_at and permalink. For comment ids, like counts and the reply relationship, use the comment exporter instead, which gives nine columns.
