WordCollector is a program that works in Java and offers the user the possibility to create their own word listings, working from web page addresses: just write an address to get all the words you want after pressing Start.
For a correct use of WordCollector the first thing to do is choose a file to save the words, and then choose the minimum length that each word should be.
So with WordCollector you can create your own dictionary (of the theme you prefer) or use those words for your own website, consuming few resources and not needing or installation, although yes, to run the program it is necessary to have Java Runtime Environment installed ( JRE), and open WordCollector with it.
You can free download WordCollector 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
