How many people commented your keyword?

A keyword is a word or short phrase that turns up in many comments because people were told to write it, or because they all want the same thing. The tool looks for three kinds, and the table marks the first two so you can see which one you are reading.

• The word your caption asks for. Lines such as “Comment GUIDE” or “Type LINK below” are found in English captions, and that word is always counted, even if it is a common one.
• Words that read like a request. Link, price, info, details, PDF and similar words, when they appear in short comments. Two or three short comments are enough, so a small post still gets an answer.
• Anything else said again and again. These appear in the table without a label. A word is only called a request when it makes up a good share of the comments and is mostly written on its own, because a word repeated is not always a word asked for.

Counting is forgiving about spelling. Capitals and accents on letters make no difference, so “guía” and “GUIA” match, and stretched letters are squeezed, so “guideeee” counts as “guide”. A comment that says GUIDE three times still counts once. A comment that is only emoji, or only tags a friend, has no words to count, and the page says how many of those it set aside.

Tip: If you asked for the word in the video rather than the caption, type it into the “Check a word of your own” box. It counts that word in the comments already read and fetches nothing more.

Comments arrive newest first, 15 at a time, and the tool reads up to five pages: at most the newest 75. When a post has no more than that, every comment it can read is read, the count is exact, and the answer is labelled “Counted in full”.

On a bigger post the tool counts what it read and scales the rest. Say 30 of the 75 comments used GUIDE and the post shows 122. The 47 unread comments are given the same 40% share, which gives about 49 in all, most likely between 43 and 55. The newest comments are not a random sample of the whole post, so treat that range as a guide, not a promise.

A sample can’t prove that nobody asked. If none of the 75 comments used a word on a post with 410, the plausible range still runs up to about 17 among the ones not read, and the page shows it as an estimate rather than a flat zero.

The total Instagram shows may include replies to comments. Meta’s developer documentation says its own comment count includes replies. This tool reads top-level comments only, so after the last page it can have fewer comments than the total suggests.

Only public posts can be read. A full read of a big post uses 6 of your free daily checks: one for the post and up to five for pages of comments. A post with 30 comments needs 3. A post looked up recently costs no check for its own details, and Stop ends a read at any point. If your allowance runs out the tool says when it resets.

Comments pass through to your browser one page at a time and are counted there. We don’t store those pages, and the tool never shows a username. Your browser uses usernames only to tell one person from two and to skip the account’s own replies, and they are gone when you close the tab. What we do keep, for a week at most, is the post’s own details (its numbers and caption, not its comments) so the same post isn’t looked up twice.

There is no export of commenters and no way to follow one person’s comments across posts. That was a deliberate choice: the tool answers “what did people ask for”, not “who said what”.

• Most comments use your word: keep it, say it in the video as well as the caption, and keep it to one short word.
• Few use it, but many write something else such as price or info: ask for that word next time, since people have already chosen it.
• Nobody used it: check that the word is easy to type, sits early in the caption, and comes with a clear offer.

Once a word is working, answering each comment by hand stops being practical. DMFast can reply under every comment that uses the word and start a private message with that person. Meta allows one private reply per comment, within 7 days of the comment, and DMFast works inside that rule. The first message is plain text, because Instagram doesn’t allow links or buttons in it.
