To generate from your own photo as a reference, the file has to be uploaded to Carat’s storage. Attaching a file in the chat and uploading it to Carat are two different things, so you select the original once more in Carat’s upload window.

​
How to upload

Ask for work that uses a reference file (for example, “make a profile image from this photo”) and Carat’s upload window opens. Select your original file in that window, confirm the upload has finished, then continue — Carat will work from that file.
Moving on before the upload completes means the file is not picked up. Wait for the upload to show as finished first.

​
File size limits

Files over the limit will not upload. Reduce the resolution of a photo or trim a video and try again.

​
If the upload window does not open

The upload window only opens when the AI tool you are using calls Carat’s upload feature. It does not open automatically in every environment.
  • Say in your request that you want to use a file — something like “use the attached photo as a reference” gets Carat’s upload feature called.
  • In an environment without support for the upload window, Carat may ask for a public image address (HTTPS) instead. That route supports images only.
  • If it still does not go through, attach the file in the AI agent on the Carat app or website instead.
