About
Backblaze Docs to Podcast is an open-source sample app for turning PDF, text, and Markdown documents into a two-host audio overview. OpenAI generates a Host A and Host B dialogue and synthesizes their lines into a single MP3. The Shows library lets users browse episodes, listen inline, read transcripts, and download episode artifacts. A dashboard displays shows, episodes, listening minutes, storage, and generation activity. Backblaze B2 is the app’s sole data store, accessed through its S3-compatible API. It stores show and episode manifests, source files, transcripts, and audio in per-show and per-episode paths. The app also uses OpenAI for script generation and text-to-speech. Unsupported source formats are rejected, and episode generation requires an OpenAI API key and at least one source document attached to a show. The project runs locally with `pnpm dev` to start its frontend and backend. Self-hosting prerequisites include Node.js 20.9+ or 22+, pnpm 11+, Python 3.11+, a B2 account, and an OpenAI API key. The repository is licensed under MIT; the project organization describes its samples as unofficial and unsupported.
