I have a web UI that does the exact same thing. https://veerasundar.com/wordle - you input Wordle results and it suggest words. It sourced the list of words from the Wordle itself.
I made something very similar. https://cjboco.github.io/wordfinder/ - except mine you use normal keyboard to create your word and the on screen keyboard to exclude the characters. Think I prefer your way.
