Govoriti is a structured A1–C1 Croatian language course with AI-powered speaking checkpoints and correction loops, positioned against the absence of comprehensive Croatian in mainstream apps like Duolingo. The product demonstrates pedagogical thoughtfulness (input-notice-produce-repair-review scaffolding) and has live content, but shows minimal external traction or revenue evidence beyond a recent SideProject post.

One insight: This is a well-designed niche language course with copyable tech (LLM correction, spaced review, speech recording), but without founder distribution, revenue proof, or multi-source demand signals, it remains pre-product-market fit and vulnerable to replication by better-resourced operators (Duolingo, Babbel) if the niche proves valuable.
