This is a list of websites on usability tools that I have bookmarked over time. It is not comprehensive and I have not tested any of them. I have other bookmarks not included here, for wireframing/ prototyping, usability in general etc.

Content - readability
This readability test tool gives you a list of sentences to consider rewriting.
Readability focusing on the difficulty of the words used rather than sentence length etc. Gives comprehensive stats, a graph showing where in the text the difficult words are then the text with difficult words highlighted.
Gunning Fog, Flesch Reading Ease, and Flesch-Kincaid are reading level algorithms that can be helpful in determining how readable your content is. Reading level algorithms only provide a rough guide, as they tend to reward short sentences made up of short words. Whilst they're rough guides, they can give a useful indication as to whether you've pitched your content at the right level for your intended audience.
