LennyKache holds 2,205 ideas drawn from all 311 episodes of Lenny’s Podcast, based on the transcripts Lenny made available.

This is not meant to be a substitute for Lenny’s own bot or for other AI tools, such as Grok Bot, to answer questions.

Instead, LennyKache is meant to show you ideas you wouldn’t think to ask for. Every entry carries the person who said it and is sourced to the episode.

There are three types of entries:

• Insights are standalone observations; the test is “That’s interesting”.
• Concepts are named, transferable ideas; the test is “That’s a tool I can use”.
• Stories are specific cases you draw the lesson from; the test is “That shows it”.

This project was inspired by IdeaKache, a personal collection of ~2,500 ideas that was nine years in the making. Try it at https://ideakache.com
