Generate an AI podcast (MP3) from one or more URLs using the open-source Podcastfy project. Use when the user says “make a podcast from this URL/article/video/PDF”, “turn this webpage into a podcast”, or wants an MP3 conversation-style summary from links. Uses Gemini for transcript generation via GEMINI_API_KEY and Edge TTS for free voice.
Generate a podcast-style audio conversation (MP3) from a URL (or multiple URLs) using podcastfy.
This skill provides a wrapper script that:
{baseDir}/.venv)podcastfyffmpeg is installed on the host.Ubuntu/Debian:
sudo apt-get update && sudo apt-get install -y ffmpeg
Set env var GEMINI_API_KEY (recommended), or create a project .env and export it before running.
Example keys file: {baseDir}/references/env.example
Generate an MP3 from a single URL:
cd {baseDir}
export GEMINI_API_KEY="..."
./scripts/podcastfy_generate.py --url "https://example.com/article"
Multiple URLs:
cd {baseDir}
./scripts/podcastfy_generate.py --url "https://a" --url "https://b"
Long-form:
cd {baseDir}
./scripts/podcastfy_generate.py --url "https://example.com/long" --longform
The script writes outputs under:
{baseDir}/output/audio/ (MP3){baseDir}/output/transcripts/ (transcript)Podcastfy prints the final MP3 path on success.

For TechCrunch categories, prefer the RSS feed:
This reduces breakage from:
We observed podcastfy can occasionally produce an MP3 that is effectively empty/truncated (e.g., a ~261-byte file), which shows up as 0s in Telegram.
This wrapper now validates MP3 output and will automatically fall back to edge-tts synthesis from the latest transcript when the MP3 is invalid.
