                    AI Studio relies on the <strong>free and open-sourced</strong> third-party app <strong>Pandoc</strong> to process and retrieve data from local
                    Office files (ex. <strong>Word</strong>) and later other text formats like LaTeX.

                <MudJustifiedText Typo="Typo.body1">
                    Unfortunately Pandoc's GPL license is not compatible with AI Studios licences, nonetheless software under GPL is generally free to use and 
                    free of charge as well. Therefore you have to accept Pandoc's GPL license before we can download and install Pandoc for free
                    automatically for you <strong>(recommended)</strong>. However you can download it yourself manually with the instructions below.
