How it works

Three steps, no learning curve

01

Say what the post is about, the goal, and the tone you want.

Pick from options

Get several captions with a hook, a message and a call to action.

03

Edit and schedule

Tweak a line, then send it straight to your calendar in the product.

Tips

Get more out of it

  • Lead with the hook, not the context — the first line has to earn the second.
  • One idea per caption. If you are making three points, you probably have three posts.
  • End with one clear action: save, comment, tap the link. A caption with no ask usually gets no action.
