Private by design
Processing, rescue history, and diagnostics stay inside the app container on your iPhone.
Night photos · on device
Bring the light back.
NightRelight relights people and subjects in underexposed night photos while keeping the scene recognizably night. The model runs on your iPhone, so your photo never needs to leave it.

Purpose-built
One focused job: rescue bad light at night.
NightRelight is not a face generator, beauty filter, or general photo editor. It corrects illumination in dark photos and keeps the background close to the original night atmosphere.
No hidden bill
There is no subscription, in-app purchase, paywall, ad network, or paid cloud inference.
Compare before you save
NightRelight is designed for lighting, not face replacement. Model-based processing and noise reduction may change fine details, especially at high strength. Compare with the original and save only results you like.
Simple workflow
Pick. Relight. Compare. Save.
Choose a dark photo
Use the system photo picker, or optionally scan a selected month for underexposed portraits. No sample photos are bundled.
Let your iPhone process it
The bundled Core ML model and finishing pipeline run locally. No internet connection is required for relighting.
Inspect the real difference
Use the before-and-after view, adjust the strength, then save only when you are satisfied.
