CNF / GNF is a software tool that automatically converts any given context-free grammar into both Chomsky Normal Form (CNF) and Greibach Normal Form (GNF). With this application, users can quickly and easily generate CNF and GNF for any context-free grammar. To use, simply run the application and create a new project, enter the grammar, and click "done" to receive the CNF and GNF grammars, as well as the new grammar at each transformation step.
