A New Push for Edge: Microsoft Retires Its Popular Editor Extension

In August 2025, Microsoft announced the discontinuation of its Microsoft Lens document scanner app, and now the company has decided to retire the Microsoft Editor AI extension. Users may continue to access it until 31 October 2025, after which the extension will be permanently deactivated. Launched in April 2020, Microsoft Editor was designed to assist with text editing, error detection, and content refinement directly within browsers, and it later gained AI-driven enhancements.

Microsoft now regards the standalone extension as redundant because its core functionality has been fully integrated into the Microsoft Edge browser, meaning those wishing to retain the features must migrate to Edge. In its official support notice, according to Microsoft, “Microsoft Editor browser extensions for Microsoft Edge and Google Chrome—AI-powered writing assistants offering grammar, spelling, and style suggestions—will be retired and no longer supported after October 31, 2025.

This change reflects our ongoing efforts to consolidate writing assistance into the built-in proofing experience in Microsoft Edge.” Users relying on the extension will transition to Edge’s native capabilities, effectively shifting from extension-based support to a built-in feature.
