Users could upload extensive documents, such as books or research papers, but the AI hosts would choose topics somewhat arbitrarily, making the podcasts less focused and sometimes too lengthy or too brief. The new "customize" feature allows users to direct the AI to focus on specific parts or themes in their documents, making the podcasts more relevant and useful[3].
