Installation and Login

What do I need in order to use Grammarly Lite?

Grammarly Lite is a free browser extension for Chrome, Firefox 4+ and Safari browsers. The support for Internet Explorer, Opera, or other browsers is not planned at this time.

Do I need to be subscriber to use Grammarly Lite?

No. Grammarly Lite is an absolutely free product.

Why do I need to enter my email address?

Grammarly Lite saves your custom dictionary in the cloud, so no matter what website you go to and write on, your dictionary follows you. We ask you for your email address to be able to authenticate you and to access your custom dictionary every time you use Grammarly Lite.

How do I know if Grammarly Lite has been installed successfully?

Once you have installed and activated Grammarly Lite, you should see an installation confirmation screen.

To verify that Grammarly Lite has been successfully activated, go to your Facebook account (or any other website that Grammarly Lite supports) and look for a Grammarly Lite icon. If the icon is grey, click on it and activate Grammarly Lite. If you do not see the icon, it means that the installation was not successful and you will need to go through the steps described in the Grammarly Lite Knowledge Base.

Removing Grammarly Lite

How do I uninstall Grammarly Lite

To uninstall in Firefox, go to the Tools menu and select “Add-ons”. In the “Extensions” tab, click on the Grammarly add-on and click the Uninstall button. Finally, you'll have to restart Firefox.

To uninstall in Chrome, click on the Chrome Controls icon next to the address bar. Click “Tools”, then “Extensions”. Click on the Uninstall link for the Grammarly extension. Finally, you'll have to restart Chrome.

To uninstall in Safari, open the Safari preferences, click “Extensions”, and click the “Uninstall” button for the Grammarly extension. Click on the Uninstall link for the Grammarly extension. Finally, you'll have to restart Safari.

If you think you might try Grammarly again later, you can temporarily disable the add-on instead of removing it completely: just click “Disable” instead of “Uninstall”. Disabling the add-on has the same effect as uninstalling it — you won’t see Grammarly spelling and grammar highlights any more — but if you want to try Grammarly again, all you have to do is click Enable.
