Verso

lean-lang.org·Infrastructure

Verso is a platform built on the Lean theorem prover for authoring documents, books, course materials, and websites. It allows writers to embed Lean code that is automatically type-checked during rendering. Every rendered page can be interactive, and the entire system leverages the Lean ecosystem. It is ideal for creating verifiable educational content, research papers, or technical books where correctness of embedded examples is paramount.
