You can choose the main dictionary of words it should use, and can also choose to add in groups of words.
If you turn on Advanced Features, you can provide phases which should be included, as well as words you wish to exclude.
This implementation runs entirely in your browser. The only things transmitted back to my website are the dictionaries and word lists that are downloaded.
However, it also uses AngularJS and ngTagsInput, and I dont know what kind of tracking they do.
A warning though, if you give it a very complex input
and/or ask it to generate a lot of anagrams, it can cause your brwoser to become slow or even crash.
You can see some of my favorite anagrams that I've found.
I'm always looking for feedback, so if you have any, just click on the link on the bottom of the page to email me.
