Class Key

Class Key retrieves teacher-prepared English lesson settings using a six-character class code. Learners can confirm the lesson title and version, then use the returned scenario, AI role, optional English level, and feedback settings for practice in ChatGPT. The tool does not receive student identities, answers, or chat transcripts. It records usage counts and enforces request limits. Teacher sign-in and in-app reporting on the companion website are not yet available; a public sample lesson is available with code CKTEST.
