Spell Check Not Working in Chrome? Fixes

If spell check has stopped working in Google Chrome, the fix is usually a quick settings toggle, a browser restart, or clearing the cached spelling data. This article walks through every practical fix, from the built-in Chrome settings to clearing corrupted dictionaries and checking extension conflicts.

Why Spell Check Stops Working in Chrome

Chrome’s spell checker is a local feature that compares the words you type against a built-in dictionary. It normally works without any extra software, but several things can quietly break it:

• An update changed your settings – Chrome updates can reset or disable the spell check toggle without warning.
• Corrupted dictionary cache – The stored list of your custom words and learned corrections can become damaged, causing the checker to stop entirely.
• Extension conflicts – Grammar or writing extensions (like Grammarly or ProWritingAid) sometimes disable Chrome’s native checker to avoid double underlining.
• Hardware acceleration glitches – In some versions, GPU rendering interferes with the red underline display.
• Profile corruption – A damaged Chrome user profile can break many features, including spell check.

Quick Fix: Turn Spell Check Back On

Start with the most direct solution. Chrome’s spell check setting is per-language and can be turned off accidentally. Here’s how to check it:

1. Open Chrome and click the three-dot menu (top right) → Settings.
2. Go to Languages (under “You and Google” or “Advanced” depending on version).
3. Click the three-dot menu next to your language and make sure “Use spell check” is checked.
4. If it’s already checked, toggle it off, wait a few seconds, then toggle it back on.

After toggling, restart Chrome completely (close all windows, not just the tab) and test in a text field. This fixes the issue for a large number of users because Chrome sometimes loses the setting after an update.

Clear the Spelling Dictionary Cache

If the toggle is on but underlines still don’t appear, the dictionary cache is likely corrupted. Chrome stores your custom words and learned corrections in a file called Custom Dictionary.txt (on Windows) or similar on Mac/Linux. Clearing it forces Chrome to rebuild the dictionary:

1. Close Chrome completely.
2. Press Windows + R (Windows) or open Finder (Mac).
3. Type %LOCALAPPDATA%\Google\Chrome\User Data\Default on Windows, or ~/Library/Application Support/Google/Chrome/Default on Mac.
4. Find the file named Custom Dictionary.txt and delete it (or rename it to Custom Dictionary.bak to back it up).
5. Restart Chrome. It will create a fresh dictionary file.

Note: This removes any words you manually added to the dictionary. You’ll need to re-add them, but the spell checker will work again.

Check for Extension Conflicts

Extensions that provide their own spell check or grammar checking often disable Chrome’s native one. The most common culprits are Grammarly, LanguageTool, and similar writing assistants. To test:

1. Open Chrome and go to chrome://extensions.
2. Toggle off all extensions (or just the writing-related ones).
3. Restart Chrome and test spell check in a text box.
4. If it works, turn extensions back on one by one to find the culprit.

If you find a conflicting extension, you have two options: keep the extension and disable Chrome’s spell check (since the extension provides its own), or uninstall the extension and rely on Chrome’s native checker. There’s no harm in having both active, but some extensions intentionally turn off the native one to avoid double underlines.

Reset Chrome’s Spell Check via Flags

Chrome has experimental features (flags) that can sometimes be the cause. If you’ve ever changed flags related to spell check, reset them:

1. Type chrome://flags in the address bar and press Enter.
2. Click Reset all (top right corner).
3. Restart Chrome.

This resets all experimental settings to default, which can fix issues caused by a flag like “Use the Windows spell checker” or “Use the mobile spell checker” if they were enabled and incompatible with your system.

Repair or Reinstall Chrome

If none of the above works, the Chrome installation itself may be damaged. On Windows, you can use the built-in repair tool:

1. Go to Settings → Apps → Apps & features (Windows 10/11).
2. Find Google Chrome, click it, and select Modify.
3. Choose Repair and follow the prompts.

On Mac, the simplest repair is to reinstall Chrome from the official site – it will overwrite the existing installation without deleting your bookmarks or passwords. Before reinstalling, you can also try creating a fresh user profile:

1. Close Chrome.
2. Rename the Default folder in the Chrome User Data directory (as in the dictionary step) to Default.old.
3. Restart Chrome – it will create a new profile. Test spell check there.

If the new profile works, you can migrate your bookmarks and passwords from the old folder, or simply start fresh.

Frequently Asked Questions

Why is spell check not working in Chrome on my Android phone?

On Android, Chrome uses the system’s spell checker by default. If it’s not working, go to your phone’s Settings → System → Languages & input → Spell checker and make sure it’s enabled. Also check that the correct language is selected in Chrome’s settings under Languages.

How do I add a word to Chrome’s dictionary?

Right-click (or two-finger click on Mac) on the underlined word and select “Add to dictionary.” The word is then stored in the Custom Dictionary file and won’t be underlined again. You can also manually edit that file if you need to remove a mistakenly added word.

Does Chrome’s spell check work offline?

Yes, Chrome’s basic spell check works offline because it uses a local dictionary. However, if you have “Enhanced spell check” enabled (which sends your text to Google’s servers for better suggestions), that feature requires an internet connection. You can turn it off in Settings → Languages → Spell check → Enhanced.

Why does spell check only work in some text fields?

Some websites disable spell check on their input fields using the spellcheck="false" attribute. This is a website-level setting, not a Chrome issue. You can’t override it from Chrome’s settings, but you can copy the text into a text editor to check it.

Will clearing my browsing data fix spell check?

Clearing cache and cookies can sometimes help if the issue is related to a corrupted site-specific setting, but it’s not the primary fix. The dictionary cache is separate from browsing data, so clearing browsing data alone usually won’t resolve the problem.
