Unified logic framework

One language for every logic your system needs

UniLog brings classical, modal, temporal, epistemic, deontic, probabilistic, non-monotonic, description, dynamic, and fuzzy reasoning into a single modular framework — with SMT-backed verification and formal guarantees.

Guided walkthrough

A hands-on path from your first formula to a working model with temporal, epistemic, and probabilistic constraints — each chapter ends with runnable code.

Parse your first UniLang formula
Build models with worlds, transitions, and valuations
Combine temporal, epistemic, and deontic operators
Verify constraints with the SMT encoder
