Building SuomiSanat With AI Agents
For a while, I wanted to see how far AI coding agents could take a real small product instead of a one-screen demo. SuomiSanat was a good test case. It is a Finnish YKI level 3 vocabulary trainer built with React, TypeScript, Tailwind, a versioned JSON word dataset, offline-first progress tracking, optional Supabase sync, and Playwright coverage. The public repo only ships a small self-authored sample dataset, but the app structure is the same one I would use for a larger private list.
