The feature currently does not support straightening individual words, tables, images, formulas, highlighter ink, or underlines. It also only works for languages with a Latin alphabet. Still, it’s useful for making your writing a bit easier to understand, especially if you want to share notes with other people.

The Straighten feature is currently only in the OneNote Beta Channel on Windows, in OneNote version 2404 (Build 17530.20000) or later. There’s no word yet on when the functionality could arrive in OneNote for Mac, the web app, or the mobile apps. It’s not coming to the older OneNote for Windows 10 application—Microsoft has been moving away from that application for over two years now and merging its features with the standard OneNote app.

There’s no estimated timeline for when the Straighten feature will roll out to everyone, but it will probably be in a few weeks at the earliest. Microsoft is also still testing a new Sticky Notes app for Windows 11 that is integrated with OneNote, as well as support for Loop components and a new multi-tap gesture for ink selection.
