Straighten.

AutoAlign works out the angle the photo was taken at and reverses it, so walls stand straight and proportions stay true. Not a stretch: real camera geometry.

  • One tap. Automatic, full or vertical only.
  • Corners your way. Keep them, fill them, or crop them off.
  • Manual Fix. Drag four corners onto anything and it flattens square.
  • Nothing lost. HDR, EXIF and GPS kept. Revert anytime.

Questions.

Step-by-step videos are in the how-to guide.

What does AutoAlign do?

AutoAlign detects leaning buildings and wide-angle distortion in iPhone photos and corrects them with one tap, keeping HDR, EXIF and GPS. It also scans and files documents, and Ask Documents answers questions about them with the on-device model of Apple Intelligence.

What is the keystone effect?

When a camera is tilted up at a building, parallel vertical lines converge and the building looks like it is leaning backward. This is called the keystone effect, or converging verticals.

Does AutoAlign preserve HDR?

Yes. The HDR gain map is corrected together with the photo, so highlights and colour survive on an HDR display.

Does Ask Documents send my documents anywhere?

No. Pages are read and searched on the iPhone, and answers come from Apple's on-device model. Nothing is uploaded, no account is needed, and it works offline. It never uses Private Cloud Compute.

Which devices support Ask Documents?

A device that supports Apple Intelligence, such as iPhone 15 Pro or later, running iOS 26 or later with Apple Intelligence turned on. It works best in English. AutoAlign itself runs on iOS 17 or later and on Macs with Apple silicon.

Can Ask Documents hold a long conversation?

Not well yet. The feature is experimental. It answers single questions reliably, but the on-device model has a small memory, so long chains of follow-ups can lose earlier turns.

Does AutoAlign work as a Photos extension?

Yes. You can correct a photo from inside the Photos app without exporting or making duplicates.

Can I undo a correction?

Yes. The original stays in your library and the correction is saved as an edit you can revert at any time.

What do I do with the empty corners after a correction?

Choose to keep them, fill them from the edge colours, or cut them off for a clean rectangle of original pixels.

What photos work best?

Photos with clear straight lines: buildings, interiors, doorways, windows, posters and whiteboards. For scenes with no straight edges, drag the four corners with Manual Fix.

Is there a Mac version?

Yes. AutoAlign runs on Macs with Apple silicon, macOS 14 or later.

Straight, in one tap.
