Describe the post
Paste your caption, or write a sentence about the post. The more specific it is, the more specific the hashtags.
Free, and no account needed
Free AI Hashtag Generator
Paste a caption or describe the post, pick the platform, and get a set of specific, relevant hashtags in the language you wrote in. Leave out any you do not want and copy the rest. No account.
HOW IT WORKS
Describe it, pick, copy.
Pick the platform
A post for X gets a couple of tags; one for Instagram gets a fuller set. The tool sizes the set to match.
Keep the ones you want
Click any tag to leave it out, then copy the rest in one go and paste them into your post.
QUESTIONS
Before you upload.
Yes, with no account and no card. There is a daily limit of 20 sets per person so the tool stays available for everyone.
Tags like #love or #instagood are on millions of posts, so yours disappears among them. The tool skips that filler and suggests tags about what your post actually is, which is what people searching for it type.
No. Your text is sent to an AI model to write the hashtags and is not stored by Postally. The hashtags themselves are kept for 24 hours so an identical request answers instantly. Postally does not train AI models on it.
Yes. Write in any language and the hashtags come back in that language.
No. It suggests tags that fit your post, not live trends, and it will not claim a tag is trending.
