What is Podcast Chapters?
Podcast Chapters is a dedicated Mac application designed to streamline podcast production by adding chapter markers and managing metadata. The tool operates without encoding or re-encoding MP3 files, preserving audio quality while allowing users to insert chapters, set episode details, and embed show art directly. It supports on-device AI transcription for modern Macs, generating text or .srt files locally without data sharing or additional fees.
Users can import audio files, add chapters through a simple interface, and export the final MP3 ready for distribution. The app includes features for viewing existing metadata, importing/exporting data via CSV or JSON, and creating presets for multiple podcasts. Its native Mac integration ensures a fast, offline workflow without web uploads or clunky interfaces.
