Mathematician Uses Coding Agents to Revamp Interactive Logic Textbook into 'Lean Grimoire'

A creator of mathematical visualization tools has successfully used modern coding agents to overhaul an interactive JavaScript textbook originally launched in 2018. The updated project, provisionally titled "Lean Grimoire," transforms propositional and first-order logic exercises into a game-like environment where users apply logical rules to derive conclusions from specific hypotheses.

By leveraging AI coding assistance, the developer integrated several contemporary capabilities into the software. Most notably, the application can now generate an in-progress Lean proof reflecting the current state of the game. Additionally, a whimsical "fantasy mode" was introduced for experimental play, translating mathematical concepts into thematic items such as scrolls and potions.

The project is currently seeking community playtesters to refine its utility as an educational instrument for formal logic and the Lean theorem prover. What to watch next: Feedback from early testers regarding its effectiveness as a teaching tool.
