Class Companion: Instant AI Feedback and Tutoring for Every Student

Class Companion is an AI platform that gives students immediate, rubric-aligned feedback on written work while giving teachers back the hours they would have spent grading. Teachers create or generate assignments — short answer, essay, or multiple choice — invite students, and the platform scores responses, explains what was strong, and coaches students on how to improve. Unlimited retakes turn every assignment into a practice loop rather than a one-shot grade.

Alongside feedback, an AI tutor called Ditto answers student questions in real time, giving every learner 1:1 support whether they are in class or at home. Teachers see submissions, engagement data, and insights into where the class is struggling, so instruction can target actual gaps. The platform spans kindergarten through higher education, with strong coverage of AP courses, English, social studies, science, and world languages.

Ideal Use Case

A high-school AP teacher assigns FRQ-style practice weekly. Students get rubric-aligned feedback within seconds, revise, and resubmit; the teacher reviews the insights dashboard to see which skills need reteaching — without spending the weekend grading. Teachers report saving around 12 hours per week on assignment creation, feedback, and 1:1 instruction.
