Generative Dictionaries on the Web

Last updated 9/17/2019

The following is a list of the generative dictionaries publicly viewable on the web that I am aware of.

"Generative dictionary" here means any site, bot, or other computational thing that generates new words in an existing language, and assigns them meanings.

If you know of anything else that belongs in this list, want to submit a correction, or want your own work to be removed from this list, you can contact me at this email address.
