I do a lot of writing – be it articles/tutorials for this blog and couple of sites I write for or codes for a project am working on.
A need to compare two closely related files arises every now and then. I often resort to using one of the numerous online tools for comparing and spotting the differences between two files.
Although virtually every IDE are bundled with sophisticated diff utilities, having to create two files just to paste in fragments of code or other bits of texts to perform a diff operation is deemed a daunting task.
Below are some of such tools for diffing text.

Wish to own your own Diff tool, I found this open-source JavaScript visual diff library called jsdifflib. Demo here.
