Lean 4 theorem proving toolkit: search lemmas, verify proofs, repair/simplify code, and get LLM-assisted informal proofs

Code transformation tools for repairing, simplifying, and extracting Lean proofs

LLM-assisted tools for informal proofs, proof strategy discussion, and code simplification

Search tools for finding Lean theorems, lemmas, and definitions in Mathlib

Isolates failing proof steps by replacing them with `sorry` and extracting them into standalone lemmas to modularize and decouple complex Lean 4 proofs.

Verification tools for compiling, validating, and disproving Lean theorems
