Old Genius is a free Chrome extension developed by Matei Marica. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

The main purpose of Old Genius is to allow users to switch between Genius's redesign and the old song page without it resetting when clicking on another page. To use this extension, users need to be signed in to Genius.

One of the key features of Old Genius is that it persistently maintains the state between pages when switching between the old song page and the redesign. This means that users can seamlessly navigate through different pages without losing their preferred layout. Additionally, this extension removes the "go to the old/new song page" buttons, providing a cleaner and more streamlined user experience.

Old Genius is an open-source extension and does not collect any user data. For more information on privacy, users can refer to the privacy policy on the project's GitHub page.
