Free, no signup.
How to use it

- 2Pick a tone and click Generate.

Tips that get more reach
- ↑The first line shows before 'more', so open with a hook or a question.
- ↑Ask for an action: save, share, comment or tag a friend.
- ↑Use 5–10 specific hashtags rather than 30 generic ones.
- ↑Write 'link in bio', because links in captions aren't clickable.
