AI Scanner: Ask Your Documents
Free · In‑App Purchases · Designed for iPad
Straighten leaning buildings in one tap. Scan receipts and letters, share or print several at once, and ask them with Apple Intelligence, privately on your iPhone.
Straighten leaning buildings in one tap, scan your documents, and ask them anything, privately on your iPhone.
STRAIGHTEN
• AutoAlign measures the angle a photo was taken at and reverses it, so walls stand straight without a stretched look. Full correction, or verticals only.
• Billboards, posters, whiteboards and artwork straighten too. With Manual Fix, drag four corners onto anything.
• Keeps HDR, EXIF, GPS and your original, and every edit can be reverted in Photos. Works inside the Photos app.
DOCUMENTS
• Scan receipts, letters, cards and slides, one shot per page. Each page is found, cropped, straightened and filed by type, with a title from Apple Intelligence.
• Search any word on the page, in the app or from Spotlight. Share as a searchable PDF. Date, place and camera stay on every page.
ASK DOCUMENTS, ON YOUR iPHONE (EXPERIMENTAL)
Ask in your own words, like "what was the total on the Hofer receipt?" The on-device model of Apple Intelligence answers and shows the document it used. Smart Search finds the right documents by meaning, and even by what a photo shows, with a search model that runs on your iPhone. Nothing is sent anywhere.
Needs a device with Apple Intelligence turned on. Smart Search needs iOS 26.4; its model downloads once after install, and search uses keywords until it arrives. Works best in English.
PRIVATE BY DESIGN
No account, no tracking, no analytics.

Bug fixes
• Swiping between documents no longer flickers.
• Fixes a crash when deleting a document right after scanning it.

AutoAlign 4.1 straightens your photos more accurately.
• Improved distortion detection. A new method measures a building's own edges and holds up in busy scenes: trees, branches, poles and street clutter no longer pull the result off true. Facades made of many short details, such as rows of windows and pilasters, are now measured as well.
• Full now applies the complete facade correction it measures, instead of stopping partway on facades photographed at an angle.
• Full now shows what it did: how many degrees it turned the facade, or that there was no facade to square, as when looking straight down a street.
• Ask Documents answers more reliably: replies stay on the question, totals across several receipts are added up correctly, and a rare word finds the right document.
Bug fixes
• The saved photo now matches the correction shown in the editor exactly.
• Overwrite Existing and Save as New can both be reverted in Photos.
• Edits are kept when you open Settings to change photo access and come back.
• Photos edited from the Photos app keep their date, place, camera and lens.
• Minor bug fixes.

4.0 Sep 29
A new, more advanced correction engine.
• A perspective engine built on true camera geometry. AutoAlign solves for the exact angle the shot was taken at and reverses it, the same mathematics professional desktop tools are built on.
• Horizontal keystone too. A skewed facade is squared, not just converging verticals.
• Not just buildings. Billboards, posters, documents, whiteboards and artwork straighten automatically as well.
• Manual Fix for anything the automatic pass cannot read. Drag any four corners onto the subject and the perspective flattens square.
• Cropping, built in, at full resolution.
• A new look, built around the photo.
Now available in 7 languages: English, العربية, Deutsch, Español, Français, Nederlands, 简体中文.

A new, advanced correction engine.
• An advanced perspective engine built on true camera geometry. AutoAlign solves for the exact angle the shot was taken at and reverses it, using the mathematics professional desktop tools are built on. Verticals stand straight, proportions stay true, and nothing is stretched to fake it.
• The complete fix, not half of it: horizontal keystone distortion is now corrected alongside converging verticals.
• Not just buildings. Billboards, posters, documents, whiteboards and artwork straighten the same way: automatically where the lines are clear, and by hand where they are not. Manual Fix now works on anything with four corners.
• A brand new look. The interface has been redesigned around the photo rather than around the controls.
• Cropping, built in. Straighten a photo and frame it in one place, at full resolution.
Plus a long list of smaller algorithm and interface fixes.
