Why Is Grammarly Not Working? | Fast Fixes That Actually Help

If you keep asking “why is grammarly not working?” while a blank toolbar stares back at you, you are not alone. This guide walks through the main reasons the tool fails to appear, stops underlining text, or throws vague messages, and shows how to check status, fix local settings, and know when to ask the company for direct help.

Why Is Grammarly Not Working? Common Causes Across Devices

When people say Grammarly is not working, they describe different situations. Sometimes the green icon vanishes from the browser toolbar. Sometimes underlines disappear inside Google Docs. In other cases the desktop app opens but will not log in, or the add-in inside Word never loads.

Start by matching what you see on screen with this overview of frequent causes. You can then jump to the section that fits your version of the problem instead of reinstalling tools at random.

Symptom	Where It Shows Up	Likely Cause
No Grammarly icon or underlines at all	Any browser or app	Extension or app turned off, outdated, or not installed
Gray widget or “Something went wrong” message	Desktop app or browser	Network, VPN, proxy, or firewall blocking Grammarly servers
Grammarly works on some sites but not others	Browser	Site-level compatibility limits or a blocked site in settings
Extension visible but no suggestions appear	Chrome, Edge, Firefox, Safari	Conflicting extension, stale cache, or disabled checks for that site
Underlines lag or editor feels slow	Web editor or Google Docs	Heavy document, slow device, or temporary service slowdown
Cannot sign in or keep getting logged out	Any version	Account issue, cookie problems, or security software interference
Add-in tab missing in Word	Microsoft Word or Outlook	Add-in disabled, not installed, or blocked by Office trust settings

Once you see your symptom in that list, fixing Grammarly becomes less random. Instead of guessing, you can move in an order that saves time and reduces the chance of breaking something that already works.

Quick Checks To Try First

Before you change settings or reinstall apps, run through a few quick checks. A quick restart of the app, browser, or device often clears simple glitches and gives you clues if the issue runs deeper.

Check Grammarly Status And Account

Open the official Grammarly Status Page in a separate tab to confirm that Grammarly itself is up. If you see a message about outages for the browser extension, editor, or desktop apps, the problem may sit on their side, so let the incident clear before you start changing your own setup. If the status page says everything is operating normally, sign out of Grammarly on the web and sign back in so that your session refreshes cleanly, then check that any paid subscription still shows as active.

Make A Basic Connectivity Check

Grammarly needs a steady internet connection to send text to its servers and return suggestions. Open a few unrelated sites in new tabs; if they fail to load or feel slow, the root cause sits with your connection, so try another network, turn off a strict VPN, or briefly pause firewall rules to see whether filters are blocking Grammarly.

Why Grammarly Is Not Working On Chrome Or Edge

Browser extensions add layers between Grammarly and the page you are typing on. Upgrades, new extensions, and stale cached data all change how the browser behaves. When Grammarly stops underlining text only in Chrome, Edge, Firefox, or Safari, the extension itself or nearby browser settings usually deserve a closer look.

Confirm The Extension Is Installed And Enabled

Visit your browser’s extensions page and make sure the Grammarly extension appears in the list and is turned on. In most browsers, you can reach this page by opening the menu, choosing extensions or add-ons, and scanning for Grammarly. If it is missing, install it again from the official store, not from a third-party site, then pin its icon to the toolbar so you can see when it is active.

Rule Out Conflicting Extensions

Other extensions that interact with web content can block Grammarly by accident. Ad blockers, script filters, password managers, and translation tools all modify pages and can interrupt the script that Grammarly injects. To test for conflicts, turn off all other extensions, keep only Grammarly running, and reload the page where you write. If Grammarly returns, turn the others back on one by one until the problem reappears and then adjust or replace the extension that triggers the clash.

Clear Cache And Check Site-Specific Settings

Sometimes the browser simply holds on to old script files or cookies. Clearing cached files gives Grammarly a fresh start; after clearing, sign in again and open a site that usually works well to see whether suggestions appear. Also open the Grammarly extension menu on any page that fails and make sure the toggle that controls checks on that site is turned on, since it is easy to forget that you disabled Grammarly there in the past.

Why Grammarly Misbehaves In Word, Desktop Apps, And Mobile

When Grammarly works in the browser but not in Word, Outlook, the desktop app, or on a phone keyboard, the issue usually lies with that specific integration. Each app loads its own plug-ins and has its own security controls, so the writing assistant needs separate checks in each place, and phone keyboards follow the same pattern.

Grammarly For Windows And Mac

The standalone desktop app and system-wide helper can stop showing up if the background process is not running. On Windows and Mac, look for the floating Grammarly widget or an entry in the system tray or menu bar, and if it is missing, open the app from your applications folder, sign in again, and confirm that desktop integration remains turned on for the apps you care about. The company maintains a dedicated Resolve Issues section with extra steps for situations where checks vanish from certain apps or sites.

Grammarly For Microsoft Word And Outlook

The Office add-in depends on Microsoft’s plug-in system. If the Grammarly tab disappears from Word or Outlook, open the Office add-ins or COM add-ins manager, check whether Grammarly appears in the list, and turn it back on if it was disabled by a crash or by trust center rules. Restart Word, open a new blank document, type a few test sentences, and check whether underlines appear.

Network, Firewall, And VPN Problems That Block Grammarly

If you see a gray widget, repeated “Something went wrong” messages, or constant failures to connect, your network may be stopping Grammarly from reaching its servers. This becomes more likely on office networks, school networks, or strict home setups that block unknown domains or use deep inspection of encrypted traffic.

Try switching temporarily to a mobile hotspot or another Wi-Fi network and reload the page or app. If Grammarly suddenly springs back to life, you know the original network settings stand in the way, and on that network you may need to relax strict content filters or ask the administrator to allow Grammarly’s service domains. VPNs and security suites can create similar trouble, so a brief test with those tools turned off or in a lighter mode can confirm whether they are the source of the block.

System And Compatibility Limits That Stop Grammarly

Not every browser, device, or operating system version receives full Grammarly coverage. If you use an older browser build or a system that no longer receives updates, the writing assistant may refuse to load or may show warnings about an incompatible setup.

Scenario	What To Check	Next Step
Old browser build	Version falls behind current release	Update to the latest stable build, then test again
Unsupported browser type	Using a niche or outdated browser	Switch to Chrome, Edge, Safari, or Firefox for Grammarly work
Outdated operating system	System no longer gets security updates	Upgrade your OS or use Grammarly on a newer device
Strict corporate image	Managed device with tight policies	Ask your admin whether Grammarly is allowed software
Browser profile corruption	Extensions keep failing randomly	Create a fresh browser profile and reinstall the extension
Damaged Grammarly install	Recurrent crashes after updates	Uninstall Grammarly fully, restart, then install fresh

If you suspect compatibility trouble, check Grammarly’s help pages for current system requirements and supported versions. When the device falls outside that range, moving your writing to a supported browser or a newer machine solves odd errors that no amount of tweaking will clear.

When You Still Need Help From Grammarly

Sometimes you walk through every step in this guide and Grammarly still refuses to behave, perhaps only for a single account or only inside a narrow set of apps. At that point, sending a detailed report to the company gives their team the data they need to investigate. Visit the official Grammarly contact page, open a ticket, and include your operating system, browser version, Grammarly product version, and a short list of the steps you already tried.

Keeping Grammarly Stable For Everyday Writing

Once you solve the immediate problem, a few habits make Grammarly less likely to fail at a busy moment. Keep your browsers and apps updated, avoid running dozens of heavy extensions at once, and give large documents a chance to load before you judge whether checks have stalled.

When something odd happens, step through the same order every time: status page, quick restarts, browser checks, app-specific checks, and finally network and compatibility questions. Treating “why is grammarly not working?” as a puzzle with a fixed set of pieces turns a stressful outage into a short, repeatable routine that protects your writing sessions and keeps your editing flow steady throughout.
