A tutor that teaches. A coach that knows what comes next.
Give Aptiz your course materials and your target. It builds a learning route, teaches around the mistakes you make, and checks what you can do without help.
Aptiz is pre-launch. Early access will open gradually to students using real course materials.
Each link values this year’s quantities at the previous year’s prices; the links multiply into one index.
The fixed-base index keeps Year 0 prices for every year. The chain replaces them at every link.
Tutor on the surface.
Coach underneath.
When you are genuinely stuck, you often cannot name the exact concept, prerequisite or step that is missing. That is why “ask a better question” is not a complete answer.
Aptiz starts from your material, your target and the work you attempt. It uses that context to decide what needs attention and what kind of help should come next.
02 · One decision, four ways
Four learners answer the same short check-in on the same two lectures. Aptiz reads each set of answers differently — and none of them had to work out what to ask for.
What the run recorded
Every answer correct, including both index constructions.
Nothing on this map is unproven.
The decision
Skip instruction entirelyThere is nothing to teach. Prove each objective without help, then move on early.
What the run recorded
One product written down wrong — the method itself held.
An application slip: the method is right; the execution came apart.
The decision
Scaffold the procedureDemonstrate the whole method once, cleanly, then fade the steps back to the learner.
What the run recorded
The same substitution three times — fixed-base prices inside a chain-weighted question.
An understanding deviation: the procedure runs correctly, but on the wrong object.
The decision
Repair the conceptRebuild the idea against the specific wrong model the evidence shows, then re-derive the procedure from it.
What the run recorded
Never forms an index at all, in any question.
A structural gap: a layer underneath this objective is missing.
The decision
Drop one layerTeach the missing prerequisite first. Re-explaining the target over a hole only builds another course of bricks over the same hole.
Read from one recorded run of the Aptiz learning engine on real lecture material (ECON10003 — one example course, not the audience). The four learners and the wording of what each answer pattern shows are written by us; the routes, strategy choices and numbers are the engine’s.
03 · The coach behind the tutor
Aptiz is designed to manage the decisions around the teaching as well: where to begin, what to try next, when to remove support, and when the route itself needs to change.
Connect the goal, the available material and the time available so you have a route rather than another blank chat.
Use your work to choose the next teaching move: explain, compare, model, practise, or return to an earlier idea.
Close the explanation and ask for a fresh attempt. Feeling clear is useful; independent performance is stronger evidence.
Evidence added from this attempt
If the attempt reveals a different problem, Aptiz changes the route instead of repeating the same intervention indefinitely.

Aptiz keeps a correctable picture of what has been introduced, practised, checked independently and needs attention again. The next decision can begin from your previous work instead of starting from zero.
The record shown continues the same recorded run: seven objectives cleared, two to go, and both index objectives due back in fourteen days.

To go05 · When Aptiz may fit
You know you are stuck, but you cannot explain where the problem begins.
The notes and explanation make sense, but the next question still leaves you blank.
You have a real target and a lot of material, but no reliable way to decide what to study next.
You want AI to help you learn the work—not produce work you cannot explain.
06 · The difference
Waits for the question you decide to ask
Explains the current problem
Leaves you to judge whether it worked
Starts each conversation from the prompt
Uses your target, material and work to propose the next step
Connects teaching to a continuing route
Removes the help and asks for a fresh attempt
Carries a correctable learning record forward
Ten seconds from the same recorded run — the check-in, the pattern it found, and the unaided check afterwards. Silent.
Early access
Aptiz is pre-launch. The first early-access version will open gradually to students using their own course materials. Tell us what you are studying so we can match invitations to the right early cohort.
Matched early cohortsTell us your stage, subject and current target.
No payment at this stageJoining the waitlist does not require payment details.
A useful updateWe write when an early cohort may fit what you study.
Aptiz is an AI tutor with a coaching layer underneath. It uses your target, course material and work to decide what should happen next, then teaches and checks your understanding through a fresh attempt.
No. Aptiz is being built for the moment when you know something is not landing but cannot identify the missing concept or next step yourself.
No. The underlying learning problem can appear across stages and subjects. Early access will begin with a smaller group of students so the product can be tested responsibly with real course material.
A general AI chat responds to the prompt you provide. Aptiz is designed to carry a learning route forward: propose the next step, adjust the teaching from your work, remove support for a fresh attempt, and update what should happen next.
No. Aptiz is being built to help you learn and practise. It is not intended to produce assessed work that you submit as your own.
Not yet. Aptiz is pre-launch and access will open gradually through the waitlist.
