Class Companion – AI Grading and Tutoring Tool Reviewed

Class Companion is an AI grading and tutoring tool built for K-12 classrooms, though it holds up at the college level too. It runs on GPT-4 and sits between a teacher’s existing materials and a student’s submitted work, handling feedback at a scale that would otherwise take hours to do manually. The free version is enough for most individual teachers to get started.

What Class Companion Does as an AI Grading Tool

Teachers load a source text — a short story, a reading passage, an article — then create assessment questions around it, either manually or with AI assistance. A rubric tells the AI what to look for in a strong answer. From there, students submit responses and the platform scores and annotates them in real time.

The teacher stays in control throughout. You set what the AI rewards, how many submission attempts students get, and whether any AI-generated feedback needs adjusting before students see it.

How the Class Companion AI Tutor Keeps Students Working

The most telling part of Class Companion is what the AI tutor does not do. When tested with a sample question about A Tale of Two Cities, it acknowledged what was included — a quote from the opening chapter — and then pointed directly to what was missing. It did not complete the answer. It sent the student back to the source with a specific gap to fill.

That approach is consistent across subjects. Students who used Class Companion in one AP course passed at a 75% rate compared to the teacher’s usual 33%, according to teacher-reported figures from the platform. In another classroom, students who completed assignments through Class Companion scored in the A–B range while those who did not scored in the C–D range. These are self-reported figures from a single platform, so they should be read with that in mind, but the pattern across multiple classrooms is consistent enough to be worth noting.

The retry system reinforces this. Students do not get a score and move on. They get direction, revise, and resubmit. For teachers comparing how different platforms handle written engagement rather than live quiz formats, the Quizizz vs. Kahoot vs. Quizlet breakdown covers the main differences across the three most widely used classroom quiz tools.

Setting Up Class Companion: Teacher Workflow

Setup takes less time than expected. Upload a source text, write or generate questions, configure a rubric, and the platform handles the rest. The interface makes clear what the AI will reward in student responses and what it will flag as incomplete or underdeveloped.

Class Companion fills a different gap than live review tools. Teachers who already use Gimkit assignments for self-paced practice will find that Class Companion is built for written assessment — longer-form responses where feedback quality matters more than speed.

From the dashboard, teachers can see which students completed the assignment, how they responded to AI feedback, and where the class as a whole is struggling. Student-level and class-level data both feed into the same view.

Class Companion Pricing: Free vs. School Plans

The base version is free for teachers and students. It covers question creation, AI feedback, the Ditto tutor, rubric generation, and retry functionality. Paid school and district plans add LMS integration, deeper analytics, and advanced academic integrity detection.

Class Companion does not publish pricing publicly. School administrators contact the platform directly for a quote. In April 2025, Panorama Education acquired Class Companion, and it now operates as part of the Panorama Solara suite. The platform continues at classcompanion.com.

Is Class Companion Worth Using for AI-Powered Grading?

For most teachers, yes — provided the institution approves it. The platform keeps educators in control, keeps students doing the thinking, and avoids the pattern common to less careful AI tools where students get finished work rather than directed feedback.

One gap worth naming: large-scale, randomized studies comparing outcomes with and without Class Companion do not yet exist in published form. The teacher-reported figures are encouraging, but they are not the same as controlled research. Understanding which tools produce measurable gains — not just engagement — matters more as AI becomes standard classroom infrastructure. The data on what countries spend per student on education puts that question in broader context: significant public investment is flowing into education systems, and distinguishing tools that improve outcomes from those that merely feel useful is a real stakes question.

The design philosophy behind Class Companion is sound. Feedback tied to rubrics, student agency through revision, teacher override at every step, and compliance with FERPA and COPPA. For written assessment specifically, it is a more structured and pedagogically honest option than handing students access to a general AI chatbot. Teachers managing class rosters across multiple tools may also find it useful to pair with a platform like Gimkit classes for live, game-based review and use Class Companion for the written work that follows.

How Class Companion Compares to General AI Tools for Grading

Using GPT-4 directly for grading is possible, but it requires the teacher to do all the structuring — writing the rubric prompt, configuring the feedback tone, preventing students from just asking for answers. Class Companion does that structural work in advance. The rubric is locked in before students ever see the assignment. The tutor is configured not to give answers away. The teacher’s intent is built into the system rather than hoping the model interprets the prompt correctly each time.

The integrity detection layer adds something general AI tools cannot offer by default. Paste anomalies, tab-switching, and response similarity across students are all tracked on the paid plan. On the free plan, pasted text is still flagged for the teacher to review.

For educators using Blooket or Kahoot for competitive recall sessions, the Blooket vs. Kahoot comparison covers how those platforms differ in format and student engagement. Class Companion addresses a completely different part of the classroom workflow — the written assessment and revision cycle that quiz games do not touch.
