  • If you find a caption suggestion that you would like to use but wish some words were used differently, you can easily edit it. Each caption suggestion on InCopy has the edit option next to the copy button.


  • If InCopy is unable to correctly detect objects that you would like to generate captions for in an image, the suggested captions would not be related to the image you provide.

  • Although the InCopy app was once on the Google PlayStore, it has been taken down. This means interested individuals have to visit third-party platforms to get the app.
