 # Models4PT: Inspired by DAGitty
 
-**Models4PT** is a dynamic tool for creating and analyzing graphical causal models, inspired by the foundational work of [DAGitty](https://dagitty.net). While preserving and building upon DAGitty’s robust algorithms and user interface, **Models4PT** is being independently developed to meet the unique needs of physical therapy (PT) clinicians and researchers.
