AI tool

Caption generator

Describe your post in a sentence or two and get three captions written for the platform you pick. Free, no sign-up.

AI can make mistakes, so read it before you post.

How it works

How to use it

  1. Describe your post

    A sentence or two about what's in it and who it's for.

  2. Pick a platform and tone

    Captions are written for that platform's length and style.

  3. Copy your favorite

    Change a word or two so it sounds like you.

Tips

  • The more specific you are, the better the captions: name the place, the product or the result.
  • Put the strongest line first. Most apps cut captions off after a line or two.
  • Captions with a question at the end tend to get more comments.

FAQ

Common questions

Is it really free?

Yes. You can use the AI tools 10 times an hour and 25 times a day in total, without signing up. The limit keeps them free for everyone.

Which AI writes this, and do you keep what I type?

It runs on a DeepSeek model through OpenRouter, sent only to providers that keep no copy and don't train on it. We don't store or log what you type. To enforce the free limit we keep a counter tied to a scrambled version of your IP address, and it's deleted within 2 days. Details are in our Privacy Policy.

Can I post these with tenfeeds?
