Microsoft Editor review

Microsoft Editor is the checker many people already have. With a free Microsoft account you get basic spelling and grammar in Word for the web, Outlook, Microsoft Edge and the Edge or Chrome browser extension. Microsoft says it works in more than 20 languages. A Microsoft 365 subscription turns on advanced refinements for clarity, conciseness, formality and vocabulary. You cannot buy Editor premium alone; it comes with Microsoft 365 Personal at $9.99 per month, which also includes the Office desktop apps, Copilot features and 1 TB of storage, so the value depends on whether you want those too. Microsoft's support page says text sent from Edge for spelling and grammar checks is not stored and is deleted after processing. Compared with Grammarly it has fewer tone and rewrite tools and weaker coverage outside Microsoft apps. If you live in Word and Outlook, it is a sensible, low-friction choice.
