## Lean Grimoire project
Terry Tao started a project to modernize a 2018 Javascript interactive logic textbook called QED.
## Project background
Tao used coding agents to rebuild the game with new features including in-progress proof displays.
## Fantasy mode added
The game now includes a fantasy mode where mathematical statements become potions and expressions become scrolls.
## Screenshot example
A typical screenshot shows nearly completed proof of an assertion in the game.
## Playtesting request
Tao seeks playtesting to improve the app as a teaching tool for logical proofs.
## Original textbook
The textbook QED taught propositional and first-order logic through a crafting game approach.
## Project timeline
Tao paused the project during hectic events but resumed work in November 2026.
## Mathematical focus
The game helps users apply logic rules to reach conclusions from given hypotheses.
## Current status
The Lean Grimoire project is available for playtesting to enhance its educational value.
## User feedback
Some users found the intro tactics confusing without prior exposure to theorem provers.
## Suggested improvements
Users recommend stronger visualizations to make the game more engaging for beginners.
## Tao's background
Tao is a mathematician known for his work in mathematical logic and AI.
## Project goals
The project aims to create a more effective tool for teaching logical proofs using AI.
## Future development
Tao plans to add more features based on playtesting feedback.
## Educational impact
The game could help students understand complex logic concepts through interactive learning.
## Key takeaway

Terry Tao released an AI-powered logic game called Lean Grimoire for teaching mathematical proofs.
