Hashtag generator, sized to each platform's rules
Type what the post is about and get hashtags built from your words and a hand-picked set for your niche. Instagram gets up to 5, X the 2 its help page recommends, YouTube the 3 it shows by the title. Nothing leaves your browser.

Separate ideas with commas. Each one becomes a tag, and a niche it names adds its set.

How many hashtags each platform allows
Only what each platform says on its own pages. Where a platform publishes no number, the table says so instead of repeating one from a blog.
| Platform | Hashtags | Caption limit | Source |
|---|---|---|---|
| Up to 5 per post (a cap) | 2,200 characters | Instagram (@creators) | |
| No published cap | 2,200 characters | None published | |
| No more than 2 recommended, no cap | 280 characters | X Help Center | |
| 3 shown by the title; over 60, all are ignored | 5,000 characters | YouTube Help | |
| No published cap | 3,000 characters | None published | |
| No published cap | 63,206 characters | None published |
Caption limits come from the rules file Antwork's publishers validate against. Hashtags count toward them like any other text.
How this generator works
It does not use AI. Each idea you type becomes a tag with its spaces and punctuation removed, because both X's and YouTube's help pages say a space ends a hashtag. If your topic names one of the 16 niches, the hand-picked tags for it are added, and a place or brand you give is combined with the topic.
The niche tags are chosen by hand, not ranked by search volume, and nothing here claims a tag will raise your reach. For hashtags drawn from what your own posts already use, ask your AI through Antwork: it reads your recent posts before it drafts.
Picking which to keep
- 01Keep the tags that describe the post. A tag that only names the format, like #reels, says nothing about you.
- 02On Instagram you get 5, so spend them on the topic, the niche and the place before anything broad.
- 03On X, the help page recommends no more than 2. Hashtags weigh against the 280-character limit like any other text.
- 04On YouTube, the hashtags shown by the title come from the ones you add. Put the one that names the video first.
- 05Capitalising each word (#CoffeeShop) makes a long tag easier to read.
