Blanket Permission Highlighter is a free Chrome extension designed specifically for users of Archive of Our Own (AO3). This tool highlights authors who have granted blanket permission to podfic their works in green, making it easier for users to identify these creators. The extension is based on Rindle's FPS list, ensuring that users can access accurate information regarding blanket permissions.

In addition to highlighting blanket permission authors, the extension also offers a filtering feature. Users can filter out works from search results that do not have blanket permission, streamlining the search process for podfic creators. This functionality enhances the overall user experience on AO3, allowing for quicker and more efficient browsing of available works.
