Compare Chrome extensions: Microsoft Editor: Spelling & Grammar Checker vs KB2A Tool

Editor provides advanced writing assistance with grammar, spelling, and style suggestions across the web (1) so you can confidently write clear, concise posts and emails.

Write like a pro with intelligent writing assistance Nail the basics with free grammar, advanced grammar, spelling, and punctuation proofing. Go beyond basics with advanced style-checking for issues like clarity, conciseness, formality, vocabulary, and much more with premium (requires a Microsoft 365 subscription).

Personalize it to your needs With Editor, you can add custom words (like names you frequently use or acronyms) to create your personal dictionary; look for “Add to dictionary” when Editor makes a spelling suggestion. Your personal dictionary roams with you wherever you use Editor – across the web with browser extension and built-in to your Microsoft 365 apps. We’ve also made it easy to skip all occurrences of a spelling correction by selecting Ignore All, or skip unwanted grammar suggestions by selecting Ignore. Editor will now automatically correct misspelled words as you type. A new green highlight will show you that a word has been autocorrected. In addition, Settings gives you a way to fine-tune your preferences for writing suggestions and personalize it even further.

Write anywhere Get writing assistance on sites like LinkedIn, Gmail, Facebook, and other favorites with this browser extension. If you want Editor's assistance in the Office apps where you write the most, open Word or Outlook on the web and get suggestions to improve your documents and email.
