Hashtag generator, sized to each platform's rules

Platform rules

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.

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.

FAQ

Hashtags, answered

How many hashtags can I use on Instagram?
Up to 5 per post or Reel. Instagram announced the cap on its @creators account in December 2025, and the generator stops at 5 when Instagram is selected.
How many hashtags should I use on X (Twitter)?
X's help page recommends no more than 2 per post. It is a recommendation, not a cap, and every hashtag counts toward the 280-character limit.
How many hashtags does YouTube show?
YouTube's help page says the 3 it considers most engaging appear by the video title, and that a video with more than 60 hashtags has all of them ignored.
How many hashtags can I use on TikTok?
TikTok publishes no hashtag cap that we could find. Hashtags are caption text, so they count toward the 2,200-character caption limit.
Is this an AI hashtag generator?
No. It is deterministic: the same topic always gives the same tags, built from your words and a hand-picked niche set, all in your browser. For tags and a caption written by AI in your voice, connect Antwork to your own AI assistant and ask it there.
Can it write my Instagram caption?
Not here, on purpose. A caption needs a model, and Antwork's runs in your own AI: connect it to ChatGPT, Claude or another MCP client and it drafts the caption and hashtags from your recent posts, then schedules them.
Are these the most popular hashtags?
No, and the page does not claim they are. The niche sets are picked by hand as tags people in that niche commonly write. No tag here is ranked by search volume.
Why does a hashtag lose its spaces and punctuation?
Because a space ends a hashtag, as both X's and YouTube's help pages say. The generator joins the words and strips punctuation so every tag works as written.
