Find Words will help you with the games Scrabble, Wordle, and crosswords by suggesting words based on your input.
There is an extensive help page that tells you how to use the website, which is live here: https://snortum.net/findwords
I have never professionally worked with the languages used here. This is a hobby project, but useful thoughts can be sent to knute (at) snortum (dot) net or create a pull request.
