PodSum.app is an innovative AI tool for creating audio summaries of podcast episodes. Users simply upload their podcast episodes, add an intro and separator sound, select the desired summary length (short, middle, or long), and click "Sum it!" The tool then analyzes the episode's type and topic, extracting relevant passages to create an audio summary, which can be downloaded as an MP3 file. Currently in version 0.2, PodSum.app acknowledges potential bugs but offers a convenient solution for podcasters to produce engaging summaries. Future updates promise additional features, and all user data is deleted after summarization to ensure privacy.
