What is Class Companion?
Class Companion is an AI grading and tutoring platform built for K-12 teachers and students. It scores short answers and essays using customizable rubrics, delivers instant feedback, and provides a built-in AI tutor that coaches students in real time. The problem it solves is simple: most students never get personal guidance during the learning process. AI grading handles the time-consuming scoring work so teachers can focus on instruction instead.
Every student gets feedback tailored to their specific responses. That kind of individual attention is hard to scale in a classroom, and Class Companion makes it possible without requiring teachers to learn code or complex software.

Real-World Applications
For a high school English teacher grading 120 essays on a Friday afternoon, the workload is brutal. Class Companion handles the rubric-based AI grading for each submission, generating inline comments and score rationales automatically. The teacher reviews the results, adjusts any scores they disagree with, and gets back hours that would otherwise be lost to manual marking.
A middle school history teacher might use the platform differently. After assigning a document-based question, they can monitor which students are struggling to interpret the source material, right down to the specific criteria where points are being lost. That student-level insight lets the teacher pull a small group for targeted reteaching before the unit ends.
Students benefit in ways that go beyond just getting a grade faster. When Ditto, the built-in AI tutor, is active, a student drafting a persuasive essay gets coaching mid-draft. They find out they are missing a counterargument before they submit, not after. Paired with unlimited revisions and fresh AI grading on each resubmission, students have a genuine reason to keep improving their work.
District administrators overseeing multiple schools may find the usage tracking and roster management features useful for coordinating adoption. They can monitor how teachers across buildings are engaging with the platform, which supports decisions about training, rollout, and resource allocation.
