McFly is a Open Source Windows program in the Developer Tools category, developed by Andrew Cantino. The current version is 0.9.4; you can download it safely from its official source with the download button above.
McFly replaces your default Ctrl-R shell history search with an intelligent search engine that takes into account your working directory and the context of recently executed commands. McFly's suggestions are prioritized in real time with a small neural network.
TL;DR: an upgraded Ctrl-R where history results make sense for what you're working on right now.
