Build me a browser based tool to convert a list of strings into hyper links

I need someone to build a tool that can convert a list of strings input into hyperlinks. When I click on the generated hyperlink, it should then search the webpage represented by each generated hyperlink for a specific line of code or word. For Example: I input ABC,BCD,CDE and then the tool would convert it into [login to view URL] e.t.c., and search each such generated URL for a word or line of code that I can define. If the keyword is found in the webpage, it should simply display a tickmark next to the URL. I prefer a clean and simple interface.
