Add JIRA Internal Comment is a free Chrome extension developed by GxGL. It falls under the category of Browsers and the subcategory of Add-ons & Tools.

This extension adds a checkbox to insert "#internal#" text into JIRA's comment. With just a click, users can easily add this internal tag to their comments, making it clear that the information is meant for internal use only. This can be particularly useful when collaborating on JIRA issues within a team or organization.

It is important to note that this extension requires the Exalate JIRA Plugin to be installed in order to function properly. Without this plugin, the extension will not work. Additionally, it is recommended to use this extension only if you are not using JIRA Service Management, as the latter already includes this feature.

Overall, Add JIRA Internal Comment is a handy extension for JIRA users who need a quick and convenient way to mark their comments as internal.
