I built Lenny’s Evil Twin’s Podcast.

You paste in a company URL, and it generates a short podcast episode where “Leonard” (Lenny Rachitsky’s evil twin) roasts the company while a co-host (my persona) argues back.

The twist is that the arguments are grounded in 5 years of Lenny’s newsletter/podcast content instead of generic AI filler. (It's for the Lenny's data contest so it's sanctioned by Lenny)

Pipeline is basically: - scrape the site - infer the main strategic tradeoffs - retrieve relevant Lenny content for both the attack and defense - generate a transcript - turn it into audio

It was super fun to build this -- my favorite part is the intro music on the loading screen. The most technically challenging part was getting the RAG to work correctly. It was my first time with RAG -- Claude Code helped a lot.

I'd love some feedback, and happy to answer any questions.
