PodSum.app is an evolving AI tool for podcast audio summaries. Users upload podcast episodes, add an intro and separator sound, choose the summary length (short, middle, or long), and click "Sum it!" The tool then analyzes the episode for type and topic, cutting relevant passages into an audio summary. Users can download the summary as an MP3 file. While in v0.2 and acknowledging potential bugs, PodSum.app offers a convenient way for podcasters to generate engaging summaries, with promises of additional functions in the future. All user data is assured to be deleted after summarization.
