website to track document revisions (for 10-k's)

I believe there is a (free) online tool that can be used to see annual revisions/additions made to documents, such as 10-ks. Has anyone heard of such a thing?

Thanks in advance.

I haven't heard of one. This is pretty straightforward to do in word already though right? I guess it would save a few steps, and maybe make it a little more convenient to look over multiple years.

You can actually use microsoft word to do the same thing. here is a tutorial http://www.oldschoolvalue.com/blog/investment-tools/tutorial-to-quickly-detect-changes-in-the-footnotes/

I was thinking there was something else out there besides just using Word. I guess not? Thanks guys!

I know you can do this with word, but would you use this service if it was available?  Would you pay to use it?  If so, how much?

I wouldn't pay for it considering Word is available. Also Bloomberg and Factset offer a similar feature for those with access.

I've looked at this as well to track sneaky changes in footnotes etc. Oldschool nerds use a commandline tool called 'diff' to find differences in textfiles. These are a couple of tools that you could try:

Only problem is that I haven't found one that looks at complete websites (and not at the underlying HTML code) so I can just link it to two SEC pages and it will show me the differences.
