Grammarly Slowing Down Browser

Symptoms

Typing lag in Google Docs or web editors, a constantly spinning G icon, high CPU on long documents, or pages loading slowly with the extension on.

Why it happens

• Documents of 30+ pages - Grammarly acknowledges slowdowns with no fix yet
• Network/WebSocket problems leave the G spinning
• Conflicts with other extensions
• Corrupted cache

How to fix it

Try these in order — the most common fix is first.

1. 1. Split long documents

   1. Break docs over 30 pages into smaller files
   2. Or check sections in the Grammarly editor at app.grammarly.com

2. 2. Run Grammarly's diagnostic test

   1. Open app.grammarly.com/diagnostic-test
   2. If the WebSockets test fails, ask your network admin to allow Grammarly's WebSockets

3. 3. Clear cache

   1. Open chrome://settings/clearBrowserData
   2. Select All time and Cached images and files
   3. Clear and restart the browser

4. 4. Disable other extensions

   1. Turn off all extensions except Grammarly and test
   2. Re-enable one by one to find the conflict

5. 5. Turn Grammarly off on heavy sites

   1. Click the G icon on the site
   2. Disable checking for that site
