A simple human performance calculator developed by MITRE for building KLM, NGOMSL, and CPM-GOMS models.

Getting Started

If you’re ready to start modeling, getting Cogulator installed on a Mac or PC is fairly straight-forward.

1. Download and install Adobe AIR
2. Download and install the Cogulator Beta

The whole process shouldn’t take more than 2 or 3 minutes. Let us know if you have questions or run into any bugs.


If Cogulator doesn't work for your purposes (say, you wanted to plug into a sim or build models graphically), consider CogTool, GLEAN, SANLab-CM, or Apex.

Open Source

Cogulator is provided gratis under an Apache 2.0 license. Feel free to look under the hood. If you’d like to contribute to the project, create a pull request. Cogulator is developed in Flash CS6 and deployed as an Air application.


This is beta software: don’t use Cogulator for critical work. Make sure your models folder (Documents/cogulator/models) is backed up regularly.
