Knowt made its name as the free Quizlet alternative - AI flashcards from your notes, with spaced repetition - and has since grown into a broader AI study platform, with the Kai AI tutor and mock-exam rooms for AP, SAT and IB. None of it is built for Australian assessment, and that's the half Polarbear covers: essay marking against VCE/HSC/QCE criteria, Australian exam-style practice, and ATAR planning on official data.

Our verdict
Knowt is a genuinely good, well-priced study tool - better than Polarbear at flashcards (we don't do them), with an AI tutor and mock exams of its own for AP, SAT and IB. Polarbear wins for Australian senior students because everything points at the VCE, HSC and QCE: criteria-based essay marking, Exam Cram and official-data ATAR tools.
Frequently asked questions
Is Knowt good for Australian students?
For flashcards, yes - it's curriculum-agnostic. Its exam features target the AP, SAT and IB rather than VCE/HSC/QCE, and it has no Australian admissions tools. That's the gap Polarbear fills.
Can Knowt mark my essays?
Not against Australian criteria - Knowt's AI grading is built for AP-style free-response questions, not VCE/HSC/QCE essays. Polarbear's Essay Marking is aligned to how Australian senior essays are assessed, with a public library of real students' essays for comparison.
Is Polarbear or Knowt better for exam prep?
Different targets: Knowt's practice rooms are built around the AP, SAT and IB; Polarbear's Exam Cram runs practice for Australian curricula, and its ATAR tools handle the admissions maths. Many students use both.
