Text summarizers analyze a document and then sum it up around key points and concepts. We were taught how to summarize long pieces of text in school. Text summarization apps are just the online automatic tools that use algorithms to present a quick outline of a document.

The benefit for us is that it helps us fit in the important facts in the shortest available time. It’s also a great study aid because a student is better equipped to tackle a long lesson armed with a sketchy summary.

GistWeb takes the bookmarklet approach. Gist works for Internet Explorer and Firefox. As the name itself suggests, if you want the gist of a webpage, just click the bookmark. As an added plus, GistWeb also works with html files you have saved on your local hard drive. You have to open the HTML file and click your GistWeb bookmark to get a summary of the content. Though it doesn’t have an option to tweak the scope of the summarization, it does display the percentage shortening achieved. A reduction of 50 – 55% in the few articles I tried out is significant to increase my productivity.
