Podcaster

This will listen to podcasts so you don't have to!

Getting Started

Install asdf and docker. Then run the following:

asdf install          # install erlang/elixir
docker compose up -d  # start db
mix setup             # deps, db migrations, tailwind, esbuild
iex -S mix phx.server # start server in interpreter

In order to run whisper (the model that converts audio to text) you need ffmpeg installed.

Original Idea

This is based on a small series of tutorials by Code and Stuff. These videos are linked below:

• Part 1: Transcribe Podcasts with Whisper AI & Elixir in Livebook
• Part 2: Boost Your AI Projects: Cloud GPUs + Elixir

In the tutorials he transcribed podcasts using code executed from a Livebook. The goal of this project is to create a website to perform AI-based transcription, with Phoenix, Ash, and Liveview.

Example Code

alias Podcaster.Podcast

# Elixir Outlaws Podcast RSS URL
url = "https://feeds.fireside.fm/elixiroutlaws/rss"

show = Podcast.create_show_from_rss_feed_url!(url)
Podcast.create_episodes_from_show(show)
Podcast.update_transcripts(show)

Troubleshooting

To full clean and rebuild the project

rm -rf deps _build .elixir_ls
mix do deps.get + deps.compile + compile
