OneNote for Windows Gets Page-Level Proofing Language Support

Microsoft is adding more flexible proofing language controls in OneNote on Windows, aiming to make multilingual work simpler and more predictable for users who switch between languages daily.

How do the new proofing settings work in OneNote?

Until now, OneNote has applied the proofing language on a per-paragraph basis and linked it directly to your keyboard input language. That behavior often caused inconsistent spellcheck and grammar results, especially when users changed keyboard layouts mid-session. Microsoft now addresses this limitation with expanded proofing options.

With the new update, users can apply a proofing language to an entire page. Once set, all text on that page follows the same language rules for spelling and grammar, regardless of how or when the content was added. This change helps writers, students, and professionals maintain consistency in long notes or shared documents.

Microsoft also introduces a default proofing language setting that stays active even when the keyboard language changes. By disabling the “Follow keyboard input language” option, users can ensure OneNote keeps using the selected language for all new content. This feature proves especially useful for multilingual users who write in one language while typing with multiple keyboard layouts.

How to enable the new proofing language controls

1. Open OneNote on Windows
2. Go to Review > Language > Set Proofing Language
3. Select your preferred language
4. Choose Apply to whole page to affect the entire page
5. Uncheck “Follow keyboard input language” to set a persistent default

Users can still override these settings by selecting specific text or paragraphs and changing the proofing language manually when needed.

The update is rolling out to OneNote on Windows version 2512 (Build 19515.20000) and later. Microsoft plans general availability by the end of January 2026. For additional details, users can review the official Microsoft blog post.

This isn’t the only software getting improvements, as Microsoft plans to bring Agent mode to Excel early next year.
