Practise real HSC exam questions, get marked in seconds, and remember it on test day.
Built on the official NESA syllabuses · Free to start, no card · made by a student, for students
Eleven AI tools built for HSC students, all included. Three of them are shown working further down.
Four of the tools, and the actual output each one gives you. Pick one.
One purchase unlocks every tool. Click any of them to see what it does.
Every time you use a tool, whether that is decoding a topic, sitting a practice exam or getting essay feedback, your work is saved automatically and filed by subject. Nothing to copy out, nothing to lose. Come back anytime and pick up where you left off.
Decode your syllabus, practise questions, or get instant feedback on your answers.
No copying or screenshots. Everything you make is kept for you the moment it's done.
Find everything in neat subject folders for Biology, Maths and English, whenever you need it.
Ask any question and get a clear explanation, not a generic answer. The AI Chat Tutor uses Socratic coaching, renders maths in LaTeX, and can quiz you on demand before any test.
Submit any answer and get a band verdict plus specific, actionable feedback in seconds. Track your scores over time and watch your weakness radar update after every session.
Every tool is built directly from official NESA-published syllabus documents, the same ones your teachers and schools use. Decode any dot-point into what's actually examined, practise across 45 HSC subjects, and study exactly what NESA tests.
No setup weekend, no course to work through first.
Sign up free and pick the HSC courses you’re actually sitting. Every tool then stays inside them, with no wading through subjects you don’t take.
Sit a practice paper, get an essay marked, decode a dot point, or just ask the tutor. Answers come back marked with the reason for each mark, not a score on its own.
Everything you generate is saved and filed by subject automatically, and your weak topics build up as you go, so the next session knows where to start.
Other tools do one of these things. We built every one of them around the NSW HSC syllabus, so you stop juggling four apps and a chatbot.
