Why InputDojo
Busuu's distinctive feature is genuine: native speakers correct your written and spoken submissions, which no automated tool replicates. Its CEFR-mapped path is also more structured than most competitors. Where it is thin is depth in Japanese and Chinese, and it has no exam vocabulary tracking. InputDojo takes the opposite shape — no lesson path and no human corrections, but free JLPT, HSK and CEFR vocabulary tracks, a reader that imports any article or video, and AI explanations of sentences you meet in real content.
