- The site labels its N5–N1 examples as estimates, not official exam classifications.
Field notes
The homepage separates practice into recognition and recall for kanji, meaning and usage for vocabulary, sentence-form choices for grammar, and evidence-finding in short passages. It offers examples at five estimated JLPT levels before an encounter. Guest progress is device-bound; the site says switching to cloud storage requires a confirmed save and an explicit character transfer.
