Keystone AI is a simple but powerful photo studio for architectural and street photography, with four core tools — all working in your photo's original Display P3 color and resolution.
Straighten leaning buildings and converging verticals by correcting keystone distortion. When leveling a shot leaves empty corners, AI fills them in seamlessly, so you can recrop to a clean, balanced composition.
Reformat a shot to a new aspect ratio. Instead of cropping away what matters, AI paints in believable surroundings — turn a tall street scene into a wide cityscape, or reshape a frame without losing your subject.
Enlarge and sharpen your photos for crisp, detailed results — great for small or low-resolution images you want to print or reuse at a larger size.
Describe the change you want and let AI transform your photo completely — reimagine scenes, styles, and details from a simple prompt.
Every edit preserves your iPhone's original wide-gamut Display P3 color and saves back in full quality.
