The GlobalLink GO OnPage Editor is a free Chrome add-on developed by TransPerfect. It allows users to easily review and edit translations directly on their websites, in context. After installing the plugin, users can sign in using their GlobalLink GO account and navigate to the website associated with the account.

In the OnPage Editor, users can select one of their project's languages and click on any text segment on the page to view the original and translated text side-by-side. This feature provides a convenient way to compare translations and make any necessary edits. Users can modify the translated text to something different and save their changes, which will be stored in a translation memory.

It's important to note that this extension will only work on the domain associated with the user's GlobalLink GO account. Overall, the GlobalLink GO OnPage Editor is a useful tool for website owners and translators who want to review and edit translations directly on their websites.
