With PhotoRoom's Custom Prompts feature, you can describe the background that you want the AI to create. This gives you greater control over your backgrounds, as you can unleash your creativity and get the AI to create any background you want.

Custom Prompts is currently only available in English.

Note: As Instant Backgrounds are generated by AI, results may vary (especially for human hands, faces, and animals). The PhotoRoom team is working hard on improving the AI for future releases.

Note: The Web App (desktop) version of PhotoRoom has Image Guidance as well as Custom Prompts. With Image Guidance, you can set the AI to create an Instant Background that is inspired by an existing image.


On iPhone, iPad and Android

There are two different ways to create custom prompts for AI-generated Instant Backgrounds. You can either use:

  • Assisted prompts, where PhotoRoom provides a structure for you to follow, with suggestions.

  • Manual prompts, where you are free to describe the scene you want.
