Frequently asked questions
Which AI tools work with this prompt?
It is written for Gemini and ChatGPT. Both can edit a photo you upload.
What do I need to fill in?
Replace the field before you send it: TIME OF DAY. Each field shows an example in the prompt.
Will the AI change my face?
The prompt tells the AI to keep faces and identities the same, but results vary between runs. If a face drifts, regenerate or reply "keep the face identical to the original".
Is my photo uploaded to PromptUp?
No. PromptUp only gives you the text of the prompt. You upload your photo directly to the AI tool you choose, under that tool's own privacy terms.
