Hi theaussiestew, I did it by hand. The hardest part was finding a way to create the sentence similarity matrix in a fast way. I solved that problem by creating a Matrix class around Javascript's typed arrays. For the complete picture, the app itself is written in Angular because I'm familiar with it (probably overkill, really) and I'm using Mozilla's pdf.js [1] to render documents.
