Enter the post or its topic (and the niche or event if you like) and get a ranked set of hashtags people actually use on X, the community and topic tags first. Pick one or two; X buries posts that carry a wall of them.

How it works
Hashtags on X are a targeting device, not a reach hack: the timeline ranks posts by engagement and treats a pile of tags as spam, while one or two topical tags put the post in front of the community that follows them (and make it findable in search). The generator returns a ranked set: first the three to five tags the niche actually uses on X (community tags like #buildinpublic or #MarketingTwitter, event tags, the topic tag), then more specific long-tail tags, then at most three broad ones. It never suggests engagement tags (#follow, #like, #viral) or tags that are just the topic with numbers stuck on.
Use them like this: pick one or two from the top of the list, write them into the sentence where they read as words ("Shipping our #SEO tool today") or put them at the end, and keep the rest of the post plain. Each hashtag counts toward the 280 characters; the Twitter Character Counter flags a post with more than two. For the post itself, the Tweet Generator writes three under 280, and the Twitter Thread Generator writes a numbered thread.
Free, no signup. Each generation draws a small amount from your shared daily AI allowance, shown by the quota chip. Paid plans get a larger daily allowance for heavier sessions.
What you will see
- Hashtag chips
- One hashtag per chip, in ranked order; click any chip to copy it, or use Copy all for the whole set separated by spaces.
- Community and event tags
- Tags a specific group follows or uses during an event; the most useful kind on X.
- Topic and long-tail tags
- Describe the post precisely; fewer people follow them, but the right people.
- Broad tags
- At most three wide-reach tags at the end of the list. They add little on X; use one at most.
- Generate more
- Adds another batch, distinct from the tags already shown.
Frequently asked questions
How many hashtags should I use on X (Twitter)?
One or two, and only when they add something. X's own guidance says no more than two per post, and its ranking treats tag walls as spam signals. Posts with no hashtag at all do fine on X; a hashtag earns its place when it is the tag a community follows or an event uses.
Do hashtags still help on X?
For discovery inside a community and for search, yes; for raw reach, no. A post with #buildinpublic reaches people who follow that tag and turns up when they search it. A post with twelve generic tags reaches fewer people than the same post with none, because the timeline down-ranks it and readers skip it.
Where should the hashtag go in the post?
Inside the sentence where it reads as a word ("our new #SEO checklist") or at the very end after the text. Never at the start, and never as a separate line of tags. Hashtags are case-insensitive, but CamelCase (#MarketingTwitter) reads better and screen readers pronounce it correctly.
How do I find which hashtags a community actually uses?
The generator ranks those first, drawing on the tags each niche is known for on X. To confirm, search the tag on X and look at the Latest tab: a tag with posts from real accounts in the last day is alive; a tag with only bots or nothing recent is dead. The Twitter Advanced Search Builder builds that search with date and engagement filters.
Do hashtags count toward the 280 characters?
Yes, every character of them. Two short tags cost 15 to 25 characters, which is why long tags and tag walls squeeze out the actual message. The Twitter Character Counter counts the way X does and warns when a post carries more than two tags.
Can I use the same hashtags on Instagram or LinkedIn?
Not as a set. Instagram rewards a ladder of niche and community tags (up to 30); LinkedIn reads three to five; X wants one or two. The topic tags carry over, the count does not. The Instagram Hashtag Generator builds the Instagram set.
Does this tool connect to my X account?
No. Nothing connects to X or posts on your behalf; the generator works from the topic you type and you paste the hashtags yourself.
Is the Twitter hashtag generator free?
Yes, free with no signup. Each batch draws from a shared daily AI allowance shown by the quota chip; signing in on a paid Keywords Everywhere plan raises it. Every plan has a cap; higher tiers get a higher one.
