Class Companion

Learning Objectives

• Describe what Class Companion does and why instant formative feedback matters in the classroom
• Explain how AI is applied to grade writing and short-answer responses against a teacher's rubric
• Identify how the teacher-override and revision loop keep an educator in control of the feedback

What Is Class Companion?

Class Companion is an AI-powered feedback platform for K-12 teachers and students. Instead of waiting days for a teacher to hand-grade a stack of essays, students submit their writing or short-answer responses and receive instant feedback tied to the assignment's rubric. Founded in 2023, the company focuses on one specific bottleneck in education: giving every student timely, specific feedback on their work, which is one of the most powerful ways to improve learning but is nearly impossible to deliver at scale by hand.

The tool is built around formative assessment rather than final grading. Its goal is to help students revise and improve while they are still working, not simply to assign a score at the end.

What Class Companion Does

• Instant feedback — students submit writing or short-answer responses and receive specific, actionable feedback in seconds rather than days
• Rubric-tied scoring — feedback is anchored to the teacher's own rubric, so students see exactly how their work maps to the assignment's criteria
• Revision loop — students can act on the feedback, revise, and resubmit, turning a single assignment into a cycle of improvement
• Teacher override — educators review the AI's feedback and can adjust or replace any of it, keeping the teacher as the final authority
• Privacy compliance — the platform is designed to meet FERPA and COPPA requirements for handling student data

How AI Is Applied

Class Companion uses large language models to read a student's response and evaluate it against the criteria in the teacher's rubric. The AI identifies where the writing meets, exceeds, or falls short of each rubric element and generates targeted feedback explaining what to improve. For short-answer work, it assesses whether the response demonstrates the expected understanding and offers guidance rather than just marking right or wrong.

Crucially, the AI is positioned as a first-pass feedback engine, not an autonomous grader. The teacher sets the rubric, reviews the output, and can override anything the model produces. This keeps a human in the loop on the judgments that matter and lets the AI handle the repetitive work of writing detailed, consistent feedback for every student. In practice, Class Companion complements grading-focused tools such as Gradescope: where those tools speed up scoring, Class Companion emphasizes the formative feedback and revision cycle.

Who Uses Class Companion

Class Companion is used by K-12 teachers, especially in writing-heavy subjects such as English language arts, history, and science where students produce extended responses. It appeals to educators who want to assign more writing and short-answer work without drowning in grading, and to schools and districts looking to give every student more frequent, individualized feedback.

Pricing

Class Companion is sold on an enterprise, quote-based model aimed at schools and districts. Pricing depends on the number of teachers and students and the scope of the deployment. Individual teachers and schools contact Class Companion directly for current plans and pricing.

Company Details

Strengths

• Feedback at scale — delivers specific, timely feedback to every student, which is hard to do by hand across a full class load
• Rubric-anchored — ties feedback to the teacher's own criteria rather than a generic standard
• Revision-focused — the resubmit loop encourages students to improve their work, not just receive a grade
• Teacher in control — the override step keeps educators as the final judge of student work
• Privacy-minded — built to meet FERPA and COPPA obligations for student data

Limitations and Considerations

• AI feedback needs review — automated feedback can miss nuance or misjudge a creative response, so teacher oversight remains essential
• Rubric quality matters — the usefulness of the feedback depends heavily on how well the teacher's rubric is written
• Enterprise focus — the model is aimed at schools and districts rather than at individual learners
• Best in writing-heavy contexts — the value is highest for open-ended writing and short-answer work, less so for purely factual or numeric assessments

Key Takeaways

• Class Companion is an AI feedback engine that gives K-12 students instant, rubric-tied feedback on writing and short-answer responses
• Its revision loop turns a single assignment into a cycle of feedback and improvement, the heart of formative assessment
• Teachers set the rubric and can override any AI feedback, keeping a human in control of the judgments that matter
• Best for K-12 teachers in writing-heavy subjects who want to give every student frequent, specific feedback without the grading overload
