Meet GreatSummary, a website that “uses a patent pending algorithm to identify the major topics in a document.” Basically you copy and paste a url or text into Great Summary and what you get in return are bullet points summarizing the copy/pasted. See the potential?
By utilizing a mathematical technique (singular value decomposition), the site selects words that capture the crux of the text. The process continues until the number of sentences requested by the user is reached, with a limit of 100.
After using it a few times I’ve booked marked it. It’s become my on demand Cliff Notes.
