Free AI caption generator for social media

Tell us what you're posting and where. Get several captions written for that network's style and length, ready to copy, tweak and schedule.

Generated with AI. Check facts and edit to fit your voice before you post.

How to use it

  1. Choose the network the caption is for. Each one gets a different length and style.
  2. Pick a tone and the language you want.
  3. Describe the post in a sentence or two. Details like names, places and numbers make captions better.
  4. Generate and copy the one you like, or generate more for new ideas.

Tips

Lead with the hook

The first line decides whether people keep reading. Start with the most interesting part, not the background.

One post, one message

Captions work best when they say one thing clearly. Save the second idea for another post.

End with something to do

Ask a question, invite a comment or point to the link. A clear next step gets more replies.

Adapt, don't copy-paste

LinkedIn readers expect more context than TikTok viewers. Tweak each version for the network it's going to.
