MathCode MathCode
MathCode is a terminal-based AI coding assistant designed to formalize plain-language mathematical problems into Lean 4 theorems and attempt machine-verified proofs. It features a persistent Lean REPL for rapid verification and accumulates successful proofs into a reusable library, functioning as an evolving knowledge base for formal mathematics.
Version 0.3.0 introduced improved toolchain bootstrapping and infrastructure, while version 0.2.0 focused on reducing API costs by up to 90% via prefix cache request reshaping and policy controls.
As of
- Persistent Lean 4 REPL for sub-second compile checks
- Agentic theorem proving with tree-of-subgoals decomposition
- Automatic theorem and axiom library management for reuse
- Obsidian knowledge graph generation for proof dependencies
- Extensible architecture via custom skills, tools, and plugins
Formal verification of mathematical proofs, research-grade formalization, and building reusable libraries of verified theorems.
General-purpose chat tasks or users requiring a hosted, zero-setup, or non-technical interface.
Open-source research project with no commercial service or disclosed pricing; operational costs depend on user-selected model providers like OpenAI, Anthropic, or OpenRouter.
MathCode is a powerful, open-source tool for proof engineers that transforms the tedious, slow process of formal verification into a fluid, agentic workflow through persistent state and reusable knowledge.
