The Lean AI Dojo

# Practice lean with AI, rep by rep.

 A dojo is where you put in the reps. Inside are three things: coaching tools that walk you through the method, the Lean AI workshop, and LEI's lean knowledge, searchable with AI.

Built and approved by Art Smalley. One of the first Americans to work for Toyota in Japan. Every tool here is built by Art or meets his standard for faithful lean method.
