06 · FAQ

Honest answers.

lockonAI is trained on VCAA examiner reports and assessor protocols. It gets within one mark of a human examiner on ~94% of Methods short-answer responses in our internal tests. We tell you when confidence is low and flag those for a human review.

Your work is yours. We store it encrypted, never sell it, and never train public models on it. You can delete every scan with one tap from your account.

Yes. Methods and Specialist are fully supported. Chemistry is in early access. Other VCE subjects are on the roadmap based on student demand.

Five marking scans per month, one topic dashboard, and two question-generation sets — enough to mark a full practice paper and see how the weakness map works before upgrading.

Yes. One tap, no friction, no email loop. Annual plans get prorated within the first 14 days.

Photos, scans, PDFs, and iPad notes all work. It reads messy handwriting, mixed print/cursive, and the diagrams VCE students actually draw — fractions, integrals, sketches.

Stop guessing what you got wrong.
