We Teach Students How to Study for Their Dream Career.
otto is a personal study coach for the HSC. It coaches not just what to study, but how to study. It turns a student's own notes into lessons and practice exams, and builds the marks that open the door to the university course and career they are aiming for.

1,000+ students from 50+ schools study with otto
Every bar here moves because you studied, not because time passed.
Today
One clear task per subject, picked from your own weak spots and what's coming up.
Built from your class timetable and your real assessment task dates.
Explain why reaction rate increases with temperature. (3 marks)
When temperature increases, particles gain kinetic energy and move faster. This means more collisions happen, so the rate of reaction increases.
What Cost Students Marks Last Year
- Explaining a process without following it through to the outcome the question asked for
- Answering “contrast” with similarities instead of differences
- Use the number of marks as a guide to how much detail is required
- Relate your answer to the context in the question, not a pre-planned response
otto reads the real report for your subject, then builds your practice around it.
A real look at otto: your week, today's plan, a handwritten answer marked line by line, the mistakes that commonly cost marks, and a tutor that answers at 1am.
If Studying Feels Hard Right Now, You're the Normal One.
Nine in ten students who sign up tell us studying is tough or wildly up and down. Here is what that actually feels like, and what otto does about each one.
I sit down to study and have no idea where to start.
otto picks one topic — the one costing you the most marks right now — and opens it. You never face the whole course at once.
I read my notes for an hour and remember none of it.
otto turns your own notes into questions and makes you answer them. Being asked is what makes it stick; rereading is what feels like studying.
I have no idea whether I'm actually getting better.
Every topic is untested, weak or proven — and you can see which. Not a score that never moves, a list that gets shorter.
I've fallen behind and there's no way I'm catching up.
Give otto your assessment date and it works backwards from it, so the time you do have goes on what's actually being assessed.
I know what I should do, I just can't make myself start.
One topic, about fifteen minutes, already chosen. Starting is the hard part, so otto removes the deciding.
When I'm stuck at 11pm there's nobody to ask.
Otto is there, and it teaches rather than hands over the answer — so you can still do it yourself in the exam.
None of this needs you to already be organised, or already be good at the subject. That is the point of it.
From Lost to Chasing a 90+, in Four Steps.
No more staring at a wall of topics wondering where to start. otto does the planning, so the student can just get on and learn.

Practise Every Day

Walk in Chasing Your ATAR
Clear your weak spots, sit timed practice exams, and go in knowing the marks are already banked.
Your Whole Week, Handled. Every Week Pointed at the ATAR You Need.
otto plans around a student's real life. Streaks and weekly targets keep the habit going; what they measure underneath is real marked practice, not time spent in the app.
Snap a photo of your school timetable and otto reads it in, then slots focused study sessions into the free time it leaves, aimed at your next assessment task and your weak spots.
No streak-chasing gimmicks. Mastery is recency-weighted, and spaced repetition brings each topic back right before you'd forget it, the timing memory research shows makes it stick for the exam.
And not just what to study, but how. otto coaches the study skills that separate top students: active recall, spacing, interleaving and beating procrastination. They're built into every session instead of left to chance.

Know Exactly What to Do, Every Single Day.
No more wondering what to revise. otto turns the whole syllabus into a short daily plan, brings weak topics back before they are forgotten, and shows your readiness climbing toward the goal.
Every Mark Adds up to an ATAR
Set the ATAR your course needs, and otto works backwards from it. Every topic you prove and every mark you stop dropping moves you along this line.
Marked Like the Real Thing. Remembered for Good.
Snap a written answer and get it marked point by point, and turn every lesson into flashcards that come back right before you would forget them.
A Tutor That Makes You Think, Not Copy.
Trained on the HSC syllabus, the curriculum and how the best tutors teach. Ask it anything you are stuck on. It explains the concept, coaches the method, and deliberately leaves the last step to you, so it actually sticks. It never just hands over the answer.
- Grounded in the syllabus and curriculum, so it stays on course.
- Coaches the method and shows where marks are won and lost.
- Leaves intentional gaps, so you do the thinking and learn it for the exam.
The Last Six Weeks Have Their Own Section.
Past papers under real timing, marked honestly. Doing the paper is the half students already do — finding out what the answers would actually have been worth is the half that moves a score.
Where the Marks Actually Go
Every practice answer is marked point by point, so you see which marks you dropped and why. The same traps come up year after year, and otto points them out before they cost you in the real thing.
Answering “contrast” with similarities instead of differences.
Use the number of marks as a guide to how much detail is required.
Mock Exams You Can Walk Away From
Full-length practice papers on your course, timed like the real thing. Stop partway and the clock pauses — come back on any device and pick the paper up where you left it.
The Marks That Aren't Content
NESA's key words, how many marks means how much writing, what to do with reading time, and pacing yourself by the marks. None of it is content knowledge, and all of it is learnable in an afternoon.
Your ATAR Is Decided in Year 12. It's Built in Year 11.
otto knows the difference. Pick the Year 11 course and it maps that course — not the Year 12 one — so everything you see is the course you're actually doing. When you start Year 12 work in Term 4, otto moves with you.
The Right Course, Not Next Year's
Your topic map, your coverage, your practice assessment tasks and your term plan all sit inside the Year 11 course. The Year 12 course is mapped underneath for when you get there.
Assessment Tasks Marked Properly, From Now
Photograph a written answer and otto marks it the way a marker would. Year 11 marks don't count toward your ATAR — learning to write the answer does.
The Habit, a Year Early
Most Year 12s lose marks to how they study, not what they know. Building the weekly habit now is the whole advantage of starting in Year 11.

Questions, Answered.
How is this different from ChatGPT?
otto is built on the HSC syllabus and your own notes. Leading teachers and tutors train and test it against our own education model, so its answers are specific to your course — and far more accurate than a generic chatbot. It plans your week, marks like NESA, tracks your readiness, and coaches you to the answer instead of handing it over. A generic chatbot doesn't know your syllabus, your subjects or your progress.
Is it cheating?
No. Otto explains the idea and deliberately leaves the last step to you, and it won't complete your actual assessment tasks or assessments.
Which subjects does it cover?
33 HSC courses, each mapped to its current NESA syllabus (including the new English and Mathematics syllabuses), never generic study tips.
What year levels is it for?
Years 11 and 12. In NSW the Year 12 course starts in Term 4 of Year 11, so tell otto which course you're doing and it maps that one, never next year's by mistake.
Do I have to upload my notes?
No, but it's better when you do: otto builds lessons and practice from your own material and your teachers' emphasis.
How much does it cost?
Free to start, then $29/mo with every subject included. Cancel anytime, no lock-in.
Built by Real Educators, Backed by Real Research.
otto isn't just another AI app. It's founded and guided by practising teachers, and built on proven research into how tutoring and top students actually work.
Led by Real Educators
Our Head of Education is a Deputy Head of Campus at a leading Melbourne school. A panel of practising senior-school teachers advises us, so otto reflects how senior courses are really taught and marked.
Grounded in Real Research
Built on established learning science: retrieval practice, spaced repetition, and fast personal feedback. It's what makes one-to-one tutoring work.
Modelled on Top Students
We studied what high-performing students and the best tutors actually do, then built it into every student's daily plan.
Everything otto does, in one place.
Lessons From Your Own Notes

Marked Like a Real Qualified Assessor
Exam-style quizzes and assessment tasks, marked question by question against the criteria, so you see exactly where marks are won and lost.
A Daily Practice Plan
otto chooses what to practise each day using spaced repetition. No guessing what to revise, no cramming.
Otto, Your AI Tutor
Trained on the HSC syllabus and how expert tutors teach. It explains the idea and leaves the last step to you, so you learn it instead of copying an answer.
Real Past Exams, Timed
Turn an official past paper into a fresh, equivalent exam, sat under timed conditions and marked.
Snap It, Get It Marked
Photograph a handwritten answer and Otto marks it like a real qualified assessor, point by point, with exactly what would win the next mark.
Flashcards That Time Themselves
Every lesson turns into flashcards, resurfaced by spaced repetition right before you'd forget them.
Real Marks vs Readiness
Log your actual assessment task and exam results and see them against otto's readiness estimate, so the number you track is one you can trust.
See Your Exam-Readiness
Track mastery and exam-readiness across every subject, updating as you learn.
Focus Sessions Built In
