Podcast Transcribe

Transcribe with podcast-helper

Generate transcript artifacts from a podcast episode, audio file, or raw transcript, with an optional cleanup pass that uses episode-page context.

Default Workflow

1. Choose a dedicated output directory such as ./out//.
2. Run npx podcast-helper transcribe --output-dir --json.
3. Add --progress jsonl only when machine-readable progress is needed.
4. Report the generated artifact paths for audio, .srt, and .txt.
5. Ask whether the user wants cleanup. Do not run cleanup implicitly.

If you are already inside this repository and dist/cli.js exists, node dist/cli.js ... is acceptable. Do not default to repository-local build steps outside this repository. If you are inside this repository and dist/cli.js is missing, run pnpm run build before using the repo-local entry point.

Gotchas

• Prefer no-install entry points first: npx, then pnpm dlx, then a globally installed podcast-helper.
• Let the CLI auto-select the engine unless the user explicitly requests a backend or needs offline Apple Silicon transcription.
• Spotify URLs are unsupported because the audio is DRM-protected. Ask for an RSS-backed episode page, Apple Podcasts link, or direct audio URL instead.
• YouTube inputs require yt-dlp.
• Generic episode pages sometimes hide audio metadata. If source resolution fails, download the audio separately and rerun with the file path.
• Hosted transcription failures usually come from a missing or wrong provider API key.
• Local mlx-whisper runs require ffmpeg, python3, and a working runtime from podcast-helper setup mlx-whisper.
• Keep the raw transcript untouched. Cleanup should write a sibling *.cleaned.txt.

Command Forms

Default:

npx podcast-helper transcribe  --output-dir ./out/ --json

Fallbacks:

• pnpm dlx podcast-helper transcribe --output-dir ./out/ --json
• podcast-helper transcribe --output-dir ./out/ --json
• node dist/cli.js transcribe --output-dir ./out/ --json only inside this repository

For offline Apple Silicon:

npx podcast-helper transcribe  --engine mlx-whisper --output-dir ./out/ --json

Cleanup Branch

Only enter cleanup when the user asks for it or already has a raw transcript.

1. Fetch episode context with curl https://r.jina.ai/.
2. Use the page as reference context for obvious ASR repairs, especially names and proper nouns.
3. Do not summarize, invent missing content, or overwrite the raw transcript.
4. Write a sibling *.cleaned.txt file.

If no episode URL is available, clean conservatively and explicitly say that external episode context was not used.
