The development team attempted to create a program which shows the programmer what the effects of their additions are in real-time, rather than requiring them to work out the effects as they write the code.^[9] Though the program began by supporting only Clojure, it has since aimed to support Python and JavaScript.^[8] The developers claim that the software can reduce programming time by up to 20%.^[8]

It was financed by a Kickstarter fundraising campaign and subsequently backed by Y Combinator.^[10] The Kickstarter campaign aimed to raise $200,000 USD and finished with $316,720 USD.^[9]
