What Backblaze Docs to Podcast is

Backblaze Docs to Podcast is an open-source sample app that turns PDF, text, and Markdown documents into a conversational audio overview with two hosts. OpenAI creates a dialogue script and synthesizes each host’s lines into a single MP3. Unsupported source formats are rejected. The Shows library lets users browse episodes, listen inline, read transcripts, and download 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 paths organized by show and episode. The app also uses OpenAI for script generation and text-to-speech. It runs locally with `pnpm dev`, which starts the frontend and backend. Self-hosting requires Node.js 20.9+ or 22+, pnpm 11+, Python 3.11+, a B2 account, and an OpenAI API key. Episode generation also needs at least one source document attached to a show. The repository is licensed under MIT; its project organization describes its samples as unofficial and unsupported.
