Hi HN!In the last couple of weeks I've been working on Cranki:Cranki = Crosswords + Anki. (It's a stupid name tbh, haha)I like doing crosswords in Spanish (to learn vocab) but none of the apps out there allowed me to use my own list of words that I come across. So I built one instead.It's entirely client-side. No server, no database, no accounts, etc. Your words and stats are stored in local storage.I built this for myself but let me know if you like it!

Could you build this?
Yes Generating small crosswords from user vocabulary lists using standard backtracking/constraint satisfaction algorithms paired with an Anki-like SM-2 spaced repetition scheduler is a classic weekend project.
