About the Instagram Caption Generator

Enter what your post is about and pick a tone to get several caption options, each with an opening hook, your details, a call to action and hashtags. Edit any option right on the page and copy it.

Only the first ~125 characters of a caption show before “more”, so the options lead with the hook.

Frequently asked questions

How long can an Instagram caption be?

Up to 2,200 characters and 30 hashtags. Most engaging captions put the key message in the first line.

Do you keep what I type?

No. Ideas are generated in your browser from templates. If you choose “Write with AI”, your brief is sent to our AI provider to write the post and isn’t stored by us.
