About this season
What is the Building My AI Twin season about?
Cloning my voice, my face, and my workflow with the current generation of AI tools.
In what order should I listen?
Episodes are numbered, but most can be listened to standalone. The first episode usually frames the problem and the methodology; later episodes test specific tools or patterns against that baseline. If you have time for one, start with the most recent episode in the season — it tends to summarize the takeaways from the earlier ones.
Are the seasons evergreen or time-bound?
Time-bound. Each season takes a snapshot of a fast-moving category at a specific point in time. We update episode show notes when a major development changes the conclusions, but the audio itself reflects the moment it was recorded. Check the lab article (linked at the top of every episode page) for the most current view.
Where can I find the transcripts?
Each individual episode page on ctaio.dev includes the full transcript below the audio player. Transcripts are searchable and indexed by search engines, so you can also reach episode content through external search.
How do I subscribe?
Apple Podcasts, Spotify, YouTube, and direct RSS — all linked at the bottom of each episode page. The RSS feed is at https://ctaio.dev/en/podcast/feed.xml for any podcast app that takes a custom feed URL.
