Walter Adamson

Does a lot for a relatively low cost, while you do other things on other tabs. Impressive. And if you use your own key only 1/10th the cost.

Very practical and well constructed course.

Well designed tool and nice UI, great for researching complex documents like contracts or research papers, and the optional google interface is very useful especially you be able to exclude sites e.g. wikipedia, or just search certain sites. The developer is very responsive and has an ambitious roadmap which he will no doubt deliver if the results so far are a guide.
