Is Your Document Still Stuck in Red Squiggle Hell?

You’ve written a report, proposal, or lesson plan. 

It’s solid. 

But now comes the slog; clicking through every spelling and grammar suggestion one by one. 

Here's a Cool Tip:  Use the Fix Spelling and Grammar feature in Word for the Web.

Feature Explanation

Microsoft’s “Fix Spelling and Grammar” feature gives Word for the Web users a way to batch correct errors flagged by Copilot in one command. 

Instead of seeing dozens of underlined issues and having to accept or reject each suggestion manually, Copilot proposes a unified rewrite. 

You can review the result, accept all, or reject individual changes. 

The goal: let users clear low-hanging typing or grammar mistakes quickly, so they can focus time on substance. 

It’s more proactive than traditional grammar tools (Editor, built-in Word checks) that alert you as you write. 

Copilot’s approach is “scan and rewrite,” then present you a cleaned draft for review.

The new feature in Word for the web is a quiet revolution. 

What You'll Gain

• Save time with one-click proofreading.
• Eliminate distracting red squiggles.
• Improve clarity and professionalism in seconds.

Step-by-Step Instructions

Here's how to do it.

On Word for the Web (Desktop or Browser)

1. Open your document in Word for the web, word.cloud.microsoft/.
2. Select the text you want to proofread or leave it unselected to fix the entire document.
3. Look for the Copilot icon (pen with sparkles) in the left margin.
4. Click Fix spelling and grammar in the Copilot chat box.
5. Review the changes. 
6. Click Keep all to accept or Undo all to revert.
7. To undo a specific change, hover over the word and click the Undo icon.
