Could you build this?

Partial Spaced repetition, typed and spoken drills, and AI conversation are buildable with existing speech and LLM APIs. The hard part is the curated linguistic data for 19 languages, including verb tables, and reliable pronunciation assessment.

What it would actually take: The stack is a mobile app with an SRS scheduler such as FSRS, speech-to-text and text-to-speech APIs, and an LLM tutor constrained to CEFR levels. The hard parts are accurate, native-quality verb tables and vocabulary for each language and reliable pronunciation scoring. This needs linguists or licensed content plus native-speaker review.
