You’re writing a page in Notion and notice a red underline. Good — spell check caught it. But then you write “He go to the store yesterday” and nothing happens. No warning, no suggestion, nothing. That’s because Notion doesn’t actually have a grammar checker. What it does have is more limited than most people realize.

This guide explains exactly what Notion can and can’t do when it comes to spelling and grammar, how to fix common issues, and how to add proper grammar checking to your Notion workflow.

Does Notion Have Spell Check?

The short answer: sort of, but it’s not what you think.

Notion does not have a built-in proofing engine. It doesn’t ship with its own spell checker, grammar checker, or any kind of writing assistant. Instead, it relies entirely on whatever spell check is provided by your browser or operating system. The Notion Help Center confirms this in their writing and editing documentation [1].

When you use Notion in Chrome or Edge, the browser’s native spell check handles typo detection. You’ll see red underlines under misspelled words like “teh” or “recieve.” When you use the Notion desktop app, it leans on your operating system’s spell check — Windows or macOS.

What Notion does not offer at all:

• Grammar checking (subject-verb agreement, tense errors, sentence fragments)
• Style suggestions (passive voice, wordiness, clarity)
• Tone adjustments or readability scores
• Punctuation correction beyond basic spell check

So “teh” gets flagged, but “He go to the store yesterday” passes without any warning. For anyone writing documentation, project notes, or client-facing content in Notion, that gap matters.

How To Enable Spell Check in Notion

Since Notion borrows spell check from your browser or OS, you need to make sure it’s turned on at the system level. Here’s how to do it for each setup.

Notion in Chrome or Edge (Web App)

If you use Notion in a browser, Chrome or Edge’s spell checker does the work. To verify it’s enabled:

1. Right-click inside any text field in Notion.
2. Look for “Spell check” in the context menu and make sure it’s toggled on.
3. Alternatively, go to chrome://settings/languages in Chrome and confirm that spell check is enabled for your language.

Chrome offers two modes: Basic and Enhanced. Basic spell check runs locally on your machine. Enhanced spell check sends your text to Google’s servers for better accuracy. If you’re working with sensitive content in Notion, keep that privacy consideration in mind.

In Edge, go to edge://settings/languages and look for the spell check toggle under your preferred language. You can learn more about how spell check works in Microsoft Edge in our dedicated guide.

Notion Desktop App (Windows)

On Windows, the Notion desktop app uses the operating system’s built-in spell checker.

1. Open Windows Settings.
2. Go to Time & Language, then Typing.
3. Enable “Autocorrect misspelled words” and “Highlight misspelled words.”
4. Restart Notion after making changes.

If you write in multiple languages, add each language under the Language settings so Windows knows to check against all of them.

Notion Desktop App (macOS)

On a Mac, Notion uses macOS’s system-level spell check.

1. Open System Preferences (or System Settings on newer macOS versions).
2. Go to Keyboard, then Text Input, then Edit.
3. Enable “Correct spelling automatically” if you want auto-correction, or leave it off and rely on red underlines only.
4. Inside Notion, click the Edit menu in the menu bar, then Spelling and Grammar, then check “Check Spelling While Typing.”

Notion Spell Check Not Working — How To Fix

Spell check in Notion breaks more often than you’d expect. Because it depends on external systems, there are several points of failure. Here are the most common fixes.

Fix 1: Check Browser Spell Check Settings

This is the most common cause when using Notion on the web. The browser’s spell check might be disabled, or it might be set to a language you’re not writing in.

Open your browser’s language settings and confirm spell check is turned on. In Chrome, go to chrome://settings/languages. In Edge, visit edge://settings/languages. Make sure your writing language has spell check enabled.

Fix 2: Fix Language Mismatch

Your browser or OS spell checker only checks against the languages it knows about. If you’re writing in English but your system’s spell check is set to German, every English word gets flagged — or worse, nothing gets flagged at all because the system gives up.

Notion has no per-page or per-workspace language setting. The language detection comes entirely from your browser or OS. Add your writing language to the system’s language list and set it as the primary spell check language.

Fix 3: Clear Notion Desktop App Cache

The Notion desktop app can develop glitches where spell check stops responding. Clearing the cache often fixes this.

1. Quit Notion completely.
2. Delete the cache folder:
   • Windows: %AppData%\Notion\Cache
   • macOS: ~/Library/Application Support/Notion/Cache
3. Restart Notion.

This won’t delete your Notion data — everything is stored on Notion’s servers. You’re only clearing local temporary files.

Fix 4: Disable Conflicting Browser Extensions

Some browser extensions interfere with Notion’s text editor. Grammarly is a known offender — it injects its own UI elements into editable fields, and Notion’s block-based editor doesn’t always handle that well. The result can be broken spell check, cursor jumping, or text duplication [2].

To test whether an extension is causing the problem, open Notion in an Incognito or Private window (where extensions are typically disabled). If spell check works there, one of your extensions is the culprit. Disable them one by one to find which one.

Best Grammar Check Tools for Notion

Since Notion has no grammar engine of its own, the only way to add grammar checking is through browser extensions — and only when using Notion in a web browser, not the desktop app.

Here are the most practical options:

BeLikeNative is a lightweight extension built for people who write in a second language. It handles grammar correction, translation, and paraphrasing directly in the browser. It works inside Notion’s web editor without the compatibility issues that heavier tools cause. Select any text, use a keyboard shortcut, and get a corrected version instantly. If you’re looking for a free alternative to Grammarly, it’s worth trying.

BeLikeNative also works seamlessly in Gmail and Microsoft Teams, so you can keep consistent grammar checking across all your writing tools.

Grammarly offers comprehensive grammar, spelling, and style checking. However, it has well-documented compatibility issues with Notion. The extension modifies the DOM in ways that conflict with Notion’s block-based editor, causing cursor problems, duplicated text, and broken formatting. Many users disable Grammarly specifically for Notion [2]. If Grammarly itself is having issues, check whether Grammarly is currently down.

LanguageTool is an open-source option with solid multilingual support. It works reasonably well in Notion’s web editor and catches grammar errors that basic spell check misses. The free tier has a character limit per check.

Notion AI offers a “Fix grammar and spelling” feature, but it is not real-time. You must select text, click “Ask AI,” and manually choose the correction option. It works in both the web and desktop apps but adds friction to the writing flow compared to always-on browser extensions.

For Notion’s desktop app, there are no good grammar-checking options. The desktop app doesn’t support browser extensions, so you’d need to copy your text into another tool, check it, and paste it back — which defeats the purpose of writing in Notion.

FAQ

Does Notion have built-in spell check?

No. Notion does not include its own spell check engine. It relies on your browser’s spell check when used on the web, or your operating system’s spell check when used in the desktop app. There is no grammar checking at all — only basic typo detection through these external systems.

How do I add grammar check to Notion?

Install a browser extension like BeLikeNative or LanguageTool, then use Notion in your browser instead of the desktop app. Browser extensions can check grammar directly inside Notion’s editor. The desktop app does not support extensions, so there’s no way to add grammar checking to it.

Why doesn’t spell check work in Notion?

Because Notion depends on external spell check, the problem is usually at the browser or OS level. Check your browser’s language settings at chrome://settings/languages (Chrome) or edge://settings/languages (Edge) and confirm spell check is enabled for your writing language. Also test in an Incognito window — a conflicting browser extension like Grammarly can break spell check in Notion.

Does Notion AI fix grammar?

Yes, but not automatically. Notion AI has a “Fix grammar and spelling” option you can access by selecting text and clicking “Ask AI.” It is not real-time — you need to manually trigger it for each block of text. For always-on grammar checking, a browser extension is more practical.

Can I use BeLikeNative with Notion?

Yes. BeLikeNative works inside Notion’s web editor without the compatibility issues that tools like Grammarly cause. It provides grammar checking, translation, and paraphrasing. Select text, press a shortcut, and get corrections instantly.

Which is better for Notion: Grammarly or BeLikeNative?

For Notion specifically, BeLikeNative tends to work more reliably. Grammarly has well-documented compatibility issues with Notion’s block-based editor, causing cursor jumping and text duplication. BeLikeNative uses a lighter integration approach that avoids these conflicts. If you primarily use Notion for writing and need dependable grammar checking, BeLikeNative is the more practical choice.
