LLMs as Copilots for Theorem Proving in Lean
This project helps theorem provers using the Lean language by automating parts of the proof-writing process. It takes a Lean proof state as input and provides suggestions for the next logical steps, relevant background information, or even a complete multi-tactic proof. Lean theorem provers, such as mathematicians, computer scientists, or logicians, would use this to accelerate their work.
1,244 stars.
Use this if you are writing formal proofs in Lean and want AI assistance to suggest tactics, find proofs, or select relevant premises to make your proving process more efficient.
Not ideal if you are not working with the Lean theorem prover or are looking for a general-purpose AI assistant for mathematical problem-solving outside of formal proof systems.
