Typed Japanese

Interactive TypeScript-based tool for learning and verifying Japanese grammar conjugations.

Webfree

Typed Japanese is an interactive tool that encodes Japanese grammar rules as a TypeScript type-level DSL, so the compiler can verify whether a conjugation is correct, with a live in-browser playground including a Verb Lab, Adjective Lab, and Phrase Builder. It's aimed at developers, especially those comfortable with TypeScript, who want precise, interactive feedback while learning Japanese grammar.
