About the AI Social Media Caption & Hashtag Generator
Describe your post and pick a platform. You get platform-sized captions and a hashtag mix of broad and niche tags.
How it works
Captions start with a hook in the first line (the only part most people see before “more”), keep to each platform’s sweet-spot length, and end with a call to action. X captions stay under 280 characters.
