This is a site with some small Haskell lessons based on LYAH, and a bunch of exercises that can be attempted online.
I built this awhile ago, and it’s just been sitting there… I think I mostly haven’t shared it because, yes, I did build it primarily with Claude, and I still feel weird about sharing stuff made with AI. That said… it exists, and just in case anyone would find it interesting or useful… I thought I might as well share it.
The repo is public on github: GitHub - philcrissman/haskelling: A tool for learning Haskell · GitHub so if anyone has better ideas for improving the exercises, I’ll gladly try to take in pull requests. Unfortunately, actually running the app locally requires API keys for various services, which are not present in the repo, but the exercises can be tested locally without any of those API keys.
