On August 29, 2025, Microsoft announced the retirement of its popular Microsoft Editor browser extensions for Microsoft Edge and Google Chrome.
The Editor extensions will be officially deprecated on October 31, 2025, as part of Microsoft’s strategy to integrate AI-powered writing assistance directly into the native proofing tools of Edge.
Key Takeaways
1. Editor extensions retirement Oct 31 2025; moved to Edge proofing.
2. Zero admin setup; auto-enabled post-retirement.
3. Powered by Azure OpenAI with Purview logging.
Consolidation of AI-Powered Proofing Tools
Microsoft Editor has long provided advanced grammar, spelling, and style suggestions through the Poplar Editor extensions on Edge and Chrome.
Going forward, these core capabilities, including real-time syntax parsing, context-aware style checks, and AI-driven rewrite suggestions, will no longer require a separate installation.
Instead, they will be natively embedded within Edge’s proofing engine, leveraging the browser’s integrated Natural Language Processing (NLP) and machine learning models.
This change makes it easier for IT administrators and end users to deploy. There is no need to change any settings or Group Policy Objects (GPOs). The built-in proofing tools in Microsoft 365 will automatically provide the same or better functionality after the extensions are no longer used.
Users will experience smarter suggestions powered by the latest Azure OpenAI inference services, all without the latency or compatibility overhead associated with browser add-ons.
Action Required for IT Admins
Retirement date is October 31, 2025. After this date, Popular Editor extensions will no longer receive updates or support and will cease functioning.
Administrators do not need to deploy any updates or disable settings. The built-in proofing tool in Edge will assume all Editor responsibilities.
Individuals can continue using Editor-Edge and Editor-Chrome extensions until the retirement date.
Post-retirement, grammar checks, spell correction, and style suggestions will be accessible directly from Edge’s settings under “Languages and proofreading.”
Organizations that utilize Microsoft Purview for activity logging may need to adjust their monitoring policies since extension-specific telemetry will be consolidated into broader browser logs.
Users are encouraged to familiarize themselves with Edge’s new proofing UI, which includes configurable options to enable or disable AI-driven suggestions, customize dictionaries, and review change histories.
Microsoft’s retirement of the Poplar Editor extensions underscores the company’s broader effort to unify AI services within core applications, reduce fragmentation, and streamline updates.
By embedding Editor functionality into Edge, Microsoft aims to deliver seamless, high-performance, and secure writing assistance without the need for separate browser extensions.
