Checking for Chrome's built-in AI...
Hashtags are made in your browser. Nothing you type is sent anywhere.
Each app's rule
Fewer, and on topic.
02 / YouTube
3 shown, 60 at most
Up to 3 appear by the title. With more than 60, YouTube ignores every hashtag on the video.
03 / TikTok and X
A few that fit
X recommends no more than 2. TikTok gives no number and says more hashtags will not widen your reach.
Read on Instagram's, YouTube's, X's and TikTok's own help and news pages on 17 October 2026. Apps change these rules; check theirs if a post will not go through.
Questions
Good to know.
Why capital letters in hashtags?
#MorningYoga is easier to read than #morningyoga, and screen readers can read the words apart. Hashtags match either way.
Where do the hashtags come from?
From your own words: your topic, pairs of its words and single words, plus your keywords. With Chrome's built-in AI, more ideas are written on your computer; check them before you use them.
Does this show how popular a hashtag is?
No. This page does not look anything up. Search a hashtag in the app to see how many posts use it.
Is anything sent anywhere?
No. Everything happens in this tab.
