Free AI Hashtag Generator

Describe your post or topic and get 25 relevant hashtags — a smart mix of popular and niche tags to boost reach and discovery on Instagram, TikTok, LinkedIn and X.

How to use hashtags effectively

Hashtags help new audiences discover your posts. The trick is mixing reach with relevance: a few big popular tags for volume, plus several niche tags where your content can actually surface to an engaged audience. Tags that are too broad bury you; tags that are too narrow have no audience.

Match the count and style to the platform — Instagram and TikTok reward more tags, while LinkedIn and X work best with just a few targeted ones.

Frequently asked questions

How many hashtags should I use?
It depends on the platform: Instagram and TikTok reward more (up to ~15), while LinkedIn and X do better with just 1–5 targeted tags. Pick the most relevant from the list rather than using all 25 everywhere.
Should I use the most popular hashtags?
Mix them. Huge tags have audiences but fierce competition; niche tags have smaller but more engaged audiences where you can actually be seen. A blend works best.
Can I tailor hashtags to a platform?
Yes — add the platform in the optional field and the suggestions are tuned to its style and norms.
Is it free?
Yes — free with a fair hourly limit, no sign-up.
