The Superhuman Go browser extension doesn’t show writing suggestions

This article covers what to do when the Superhuman Go browser extension doesn’t behave as expected. It applies to situations such as:

• You don’t see writing suggestions in a text field
• You don’t see the Superhuman Go tab on the right side of your browser window
• You see the Superhuman Go tab, but Grammarly Proofreader doesn’t appear inside it

Work through the steps below in order. Each section addresses a different cause.

• Confirm Superhuman Go is installed and switched on
• Confirm the website is supported
• Confirm writing suggestions are switched on for the website
• Check your network connection
• Rule out conflicts with other extensions
• Check the text field
• Use Superhuman Go in an unsupported text field
• Advanced troubleshooting
• Try Superhuman Go for Windows and Mac

Confirm Superhuman Go is installed and switched on

If the Superhuman Go tab doesn’t appear at all, the extension may not be installed or may be switched off.

1. Copy and paste chrome://extensions for Chrome or edge://extensions for Edge into your address bar and press Enter.
2. Check that Superhuman Go appears in the list of extensions and that it is switched on.
3. If Superhuman Go is not on the list, install it by following the steps in this article: How to install the Superhuman Go browser extension

Note: If the Superhuman Go icon on your browser toolbar shows a red-barred circle, the extension has been deactivated on the website you’re on.

Confirm the website is supported

The Superhuman Go browser extension works on a wide range of websites. If writing suggestions don’t appear on a specific one, the website may not be supported. To check whether it is supported, type the website name in the search field on this page: Check if your favorite apps and websites work with Grammarly and Superhuman Go

If the website shows the Unsupported status, writing suggestions will not be available there.

Confirm writing suggestions are switched on for the website

The Superhuman Go extension has two settings that control whether writing suggestions appear:

• A global setting that turns writing suggestions on or off across all websites
• A per-website setting that turns writing suggestions on or off for the website you’re currently on

To check these settings:

1. Click the Superhuman Go icon on your browser toolbar.
2. Confirm that Check text with browser extension is switched on.
3. Confirm that Check for writing suggestions on… is switched on for the website you’re currently using.

If either setting is off, switch it back on, reload the page, and check whether writing suggestions appear.

Note: If the Superhuman Go icon shows a red-barred circle, the extension has been deactivated on this website, and clicking it displays a message confirming this.

Check your network connection

If the extension is turned on and writing suggestions still aren’t appearing, your network connection may be preventing Superhuman Go from reaching our servers.

Note: If you see the error message Can’t connect to Superhuman Go in the Superhuman Go tab, see Error: Can’t connect to Superhuman Go or Something went wrong.

Try the following steps in order:

1. Clear your browser’s cache and cookies by following the steps in this article: How do I clear cache and cookies?
2. Run the Self-Diagnostic Tests.
3. If the WebSockets test fails, follow these instructions: WebSockets Configuration Troubleshooting
4. On a managed network, you may need to work with your system administrator to resolve the issue.

Rule out conflicts with other extensions

Other browser extensions can sometimes interfere with Superhuman Go. To check whether this is the cause, temporarily switch all other extensions off.

1. Copy and paste chrome://extensions for Chrome or edge://extensions for Edge into your address bar and press Enter.
2. Switch all other extensions off, leaving only Superhuman Go on.
3. Reload the page and check whether Superhuman Go works.

If Superhuman Go starts working with the other extensions switched off, turn them back on one at a time to identify which one is causing the conflict.

Check the text field

Even on a supported website, individual text fields may not be compatible with Superhuman Go for the reasons below.

The text field is too short

Superhuman Go is compatible with text fields that are at least 38 pixels tall. In a shorter text field, inline underlines will not appear, and the Grammarly Proofreader agent will not detect the content of the field.

If the text field has a resize handle in its lower-right corner, drag it to make the field taller. Otherwise, try pressing Shift + Enter several times to expand the field.

The website has disabled writing suggestions for this text field

Some websites disable writing suggestions in specific text fields. When this happens, inline underlines don’t appear, and the Grammarly Proofreader agent may show “No text available” even when you’re typing.

This setting is controlled by the website owner. To confirm whether this is the case, see the advanced troubleshooting steps below.

The text field is inside an iframe (Microsoft Edge only)

An iframe is a way for a website to embed another web page within its own page. Some text fields are built this way.

In Microsoft Edge, the Superhuman Go browser extension is not compatible with text fields inside iframes. The Superhuman Go tab still appears, but inline underlines and writing suggestions are not available for text inside iframes.

Note: In Google Chrome, text fields inside iframes are supported.

To confirm whether a text field is inside an iframe, see the advanced troubleshooting steps below.

Use Superhuman Go in an unsupported text field

If a text field is not compatible with the Superhuman Go browser extension, you can still get help with your writing by using the Go agent:

1. Open the Superhuman Go tab. The Go agent is selected by default.
2. Select the text you want to check in the unsupported field, or copy and paste it directly in the Go agent chat box.
3. Ask Go to review or rewrite your selection.
4. Copy the response from Go and paste it back into the text field.

Advanced troubleshooting

The following steps use the browser’s developer tools to verify the cause of a problem. They are intended for users who are comfortable with the browser console.

The first two checks apply to both Google Chrome and Microsoft Edge. The third check applies to Microsoft Edge only.

Check whether the text field has a compatible height

1. Right-click on the text field where Superhuman Go isn’t working and click Inspect.

2. Navigate to the Console tab.

   

3. Copy the following string, paste it into the Console view, and press Enter:

   $0.clientHeight 38

If the result is false, the text field is too short to be compatible with Superhuman Go.

Check whether the website has disabled writing suggestions for this text field

1. Right-click on the text field where Superhuman Go isn’t working and click Inspect.
2. Navigate to the Console tab.

3. Copy the following string, paste it into the Console view, and press Enter:

   Boolean(document.querySelector('[data-gramm="false"]'))

If the result is true, the website has disabled writing suggestions for this text field. For more information or additional assistance, contact the website owner.

Check whether the text field is inside an iframe (Microsoft Edge only)

1. Right-click on the text field where Superhuman Go isn’t working and click Inspect.
2. Navigate to the Console tab.

3. Copy the following string, paste it into the Console view, and press Enter:

   $0.ownerDocument.defaultView.parent !== $0.ownerDocument.defaultView

If the result is true, the text field is inside an iframe. Superhuman Go is not compatible with iframes in Microsoft Edge.

Try Superhuman Go for Windows and Mac

You can also use Superhuman Go for Windows and Mac to get writing suggestions across websites and applications.

If you use both the Superhuman Go browser extension and Superhuman Go for Windows and Mac, only one product will be active in the browser at a time:

• When the Check text with browser extension option is switched on, the Superhuman Go browser extension will provide writing suggestions in the browser.
• When the Check for writing suggestions on [website] option is switched off for a specific website, Superhuman Go for Windows and Mac will initiate on that website instead if it is compatible with it.

Note: To check whether Superhuman Go integrates with a specific website, type the website name in the search field on this page: Check if your favorite apps and websites work with Grammarly and Superhuman Go
