Zenon is an automatic theorem prover based on the tableaux method. Given a first-order statement as input, it outputs a fully formal proof in the form of a Coq proof script. It has special rules for efficient handling of equality and arbitrary transitive relations. Although still in the prototype stage, it already gives satisfying results on standard automatic-proving benchmarks.
Zenon is designed to be easy to interface with front-end tools (for example integration in an interactive proof assistant), and also to be easily retargetted to output scripts for different frameworks (for example, Isabelle).
