Gizmo
Gizmo is a mobile-first study app that turns your notes, PDFs, slides and YouTube videos into AI-generated quizzes and flashcards, built around active recall so revision becomes a habit rather than a chore.
- Recall-first design that actually aids memory
- Studies from your own notes, PDFs and videos
- Gamification targets the real problem of consistency
- A study aid, not an answer-solver
- Not for deep conceptual explanation
- Grade-boost testimonials are unverifiable
- Mobile-first may not suit desktop users
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
