Instagram caption generator
Write Instagram captions from one line about your post, in a friendly, bold, question or story tone. Free, no sign-up.
How to use it
Describe the post in a few words and pick a tone: friendly, bold, a question, or a short story. You get five captions you can copy and edit.
Our AI key isn't switched on yet, so for now the captions come from templates. Use them as a starting point and add a detail only you know.
Before you post
- Put the point first. The feed cuts captions off after a line or two.
- Check the length and hashtags with the Instagram character counter. Instagram caps captions at 2,200 characters and, since December 2025, 5 hashtags.
- Keep your blank lines with the line break tool.
- See how it looks under your photo with the post mockup.
Questions
Which tone gets the most engagement?
There's no rule we can give you here, because it depends on your audience. Try two tones over a few weeks and compare them with the engagement rate calculator.
Can it write a bio too?
Use the Instagram bio generator. It keeps you under the 150-character limit.
