I was removing duplicate lines frequently, but when I used to visit other sites, I don't like the UI (User Interface) of many websites. Some sites are offering an excellent user interface, but their domains are hard to remember to visit again. So I thought of creating my website focusing on better user interface and easy to remember domain name to remove duplicate lines online. That's how this site is born.
