Friday, May 04, 2007 – Detect plagiarism on the internet

from - published startups by rachsig Copyscape is a site that aims to get rid of a big problem: the ease with which work can be plagiarized on the internet. You can register your content with the site and put their banner on your article, proclaiming to all that your work is protected by Copyscape. Then you enter the url address of your article on the Copyscape site to see if anyone has written something that is similar enough to have been copied. The site uses a Google API to search for similar word content, so that you can see if anyone has cited your work or even copied you.

The service is free, and Copyscape also offers a Premium service which has more accurate and advanced search options as well as unlimited searches. To use the Premium service, you pay by search. Each Premium search costs $0.05. Search credits are purchased in advance and can be bought as and when they are required. In their own words: "Copyscape is dedicated to defending your rights online, helping you fight against online plagiarism and content theft. Copyscape finds sites that have copied your content without permission, as well as those that have quoted you. * The free Copyscape service makes it easy to find copies of your content on the Web. Simply type in the address of your original web page, and Copyscape does the rest. * The powerful Premium service provides professional grade coverage, plus an unlimited number of searches. You may also copy and paste to search for copies of your offline content. Copyscape Premium includes integrated case tracking to manage your responses to multiple instances of online plagiarism. * The advanced Copysentry service provides ongoing protection for your entire website. Copysentry automatically scans the web every day and alerts you to copies of your content. It also includes integrated case tracking. • The Global Web Rights campaign provides the tools and information you need to defend yourself against content theft and copyright violations on the web." Why it might be a killer: The site is a logical companion to anyone who blogs or posts content on Wikipedia and so on. Even if your content isn't actually copyrighted, it is still good to be able to know when others are using it. Some questions: Five whopping cents for a search is not going to add much to the site's revenue (which comes from ads), and it may turn off users who don't want to bother with the time or the small cost
