Photo edit prompt
Before and after split image
Before and after split image: a free, copy-paste prompt for Gemini and ChatGPT. Upload your photo, paste the prompt, and fill in any [BRACKETED] fields.
The prompt
Combine my two photos into a single before-and-after image with a vertical split in the middle. Left is "BEFORE", right is "AFTER". Keep both photos exactly the same, aligned to the same scale. Add small clean labels in [FONT STYLE, e.g. white sans-serif], a thin white divider line and consistent crop and brightness on both sides.
Pro tip: Use the same angle and light in both photos to make the change clear.

- Upload your photo (a clear, front-facing one works best).

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: FONT STYLE. 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".
