Class Companion
Class Companion gives students instant, rubric-aligned AI feedback and tutoring on assignments while giving teachers back hours, with unlimited retakes, classroom insights, and strong student-data privacy for K-12 and beyond.
- Closes the feedback-and-revision loop that drives real learning
- Saves teachers substantial grading and coaching time
- Insights target instruction at genuine class-wide gaps
- Unusually thorough, documented student-privacy posture
- Best for open responses, not pure multiple-choice or drilling
- Full value needs the paid school or district tier
- Requires device access for every student
Thetawise
ThetaWise is a STEM study tool covering maths, science and engineering with step-by-step solutions, a Tutor Mode that guides through hints, generated animated video lessons, practice quizzes, flashcards and Desmos graphing, stating 765,781 students.
- Tutor Mode is the correct pedagogy and it is a first-class feature, not a toggle
- Offering Answer Directly openly is more honest than pretending students will not want it
- Video generation suits STEM, where much of the difficulty is genuinely spatial
- Uploading course material makes practice match a specific teacher's style
- Multiple superlative accuracy claims with no source we could verify
- The 95 percent improved-scores figure almost certainly reflects self-report
- Whether calculation is routed to a symbolic engine is not explained
