I recently learnt about Halo 2 and PLONK zero-knowledge circuit design and built a Wordle clone that creates ZK proofs of the grid you share afterwards. This was mostly a fun intro project for me and I wrote up my notes introducing Halo 2 and my circuit design in specific in the README that would be interesting to folks here!
I tried it on the website, but unfortunately when generating a proof, after about a minute my mobile browser crashes. I guess it's an OOM kill?
