Backblaze Docs to Podcast review
A focused self-hosted workflow for converting documents into conversational MP3 episodes.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Backblaze Docs to Podcast is an open-source sample application for turning PDF, text, and Markdown documents into conversational two-host podcast episodes. It uses an LLM to generate a dialogue script, OpenAI text-to-speech to create separate host voices, and Backblaze B2 to persist source files, transcripts, manifests, and MP3 episodes. The product is aimed at developers, technical teams, and other users who want a basic self-hosted workflow for converting documents into listenable audio rather than a hosted commercial SaaS product.
Setup and platform fit are central considerations. The application runs locally with a Next.js frontend and FastAPI backend, and it connects to Backblaze B2 for object-storage persistence and OpenAI for text-to-speech synthesis. Running it requires a Backblaze B2 account and an OpenAI API key. Once configured, the workflow covers show creation, source ingestion, episode generation, transcript viewing, inline playback, and downloads. A dashboard brings together shows, episodes, listening minutes, and storage, giving the application a useful operational view alongside its generation flow.
Its strongest case is a focused document-to-audio pipeline with enough supporting structure for ongoing shows. Two-host dialogue, distinct voices, MP3 export, transcript storage, and a shows library make it more complete than a simple one-off conversion script. The trade-off is scope: the application concentrates on core document podcast generation and does not present the broader feature set of a full podcast production platform. Choose it if you want an open-source, locally run starting point built around Backblaze B2 and OpenAI. Choose an alternative if you need a hosted service or a wider set of production capabilities.
