-This tool was originally created to supplement the [Neuromatch Academy](https://compneuro.neuromatch.io/tutorials/intro.html) materials.  A "Chatify-enhanced" version of the Neuromatch computational neuroscience course may be found [here](https://contextlab.github.io/course-content/tutorials/intro.html), and an enhanced version of the deep learning course may be found [here](https://contextlab.github.io/course-content-dl/tutorials/intro.html).
