This browser utility provides a chapter marker planning interface for audiobooks and episodic podcasts. Narrators, self-published authors, and audio editors preparing chaptered releases for platforms like Apple Books and Audible can structure chapter titles, narrator credits, and playback timestamp cues.

### Chapter Organization and State Controls The tool manages chapter track indicators directly in client state:

- **Metadata Headers:** Input fields for Audiobook / Podcast Title (defaults to "The Wealth of Nations") and Author / Narrator Name (defaults to "Adam Smith"). - **Chapter Marker List:** Displays sequential chapter cards showing timestamp cues (such as 00:00:00, 00:12:45, 00:45:10, and 01:18:20) along with chapter titles. - **Interactive Insertion:** The "+ Add Chapter Marker" button allows appending additional chapter entries with custom titles. - **Export Interaction:** Triggering the export action presents a confirmation summary of configured chapter markers.

### Concrete Planning Example An independent author organizing a four-section audiobook configures the following track layout:

1. **Title:** "The Wealth of Nations" 2. **Narrator:** "Adam Smith" 3. **Track Markers:** - Chapter 1: Introduction & Plan of the Work at `00:00:00` - Chapter 2: The Division of Labour at `00:12:45` - Chapter 3: The Principle of Exchange at `00:45:10` - Chapter 4: The Extent of the Market at `01:18:20`

### Honest Implementation Note This tool currently operates as an interactive chapter metadata and timestamp planning organizer. It does not load external audio files, transcode AAC streams, or compile binary .m4b audio containers.

### Privacy and Client-Side Execution All chapter titles, author names, and timecode offsets remain entirely inside your local browser tab. No manuscript details or project data are sent to external servers.
