Linkit gives you an easy interface with an ‘autocomplete’ field to search for content on your site, and then link to it. In other words, it provides search functionality to find the content on your site and insert the corresponding internal link.

Using the same interface, you can also insert external links. So you can insert links, both internal and external, with the same interface.

It supports internal links to nodes, users, taxonomy terms, files and comments, etc. With this module, you do not need to copy or remember the target URL, or go back and forth to find out and verify the exact link. It provides a more user-friendly interface well integrated with the insert link function of the editor.
