ZetheoLearn to think

Don't just learn the answer. Learn how to find it.

Zetheo is an AI tutor that adapts to whatever you are studying — upload your own notes, textbook chapters or past papers, from GCSEs through university to professional exams, and it builds the questions around them.

If you are sitting GCSEs, the GCSE Tier is the curated pathway inside it: content calibrated to your exam board, mapped objective by objective.

Two ways in

Bring your own material, or follow the curated course.

Both pathways use the same tutor and the same mastery tracking. Pick the one that matches what you are working towards.

Study Anything

Upload notes, slides, a textbook chapter or a past paper. Zetheo derives the structure — topics, objectives and difficulty — then tutors you through it. Built for A-levels, degree modules, professional exams and anything else you need to understand.

Upload material

GCSE Tier

The curated pathway. Content calibrated to AQA, Pearson Edexcel and OCR specifications, with foundation and higher tiers, diagnostics per topic and progress tracked from the whole qualification down to a single learning objective.

The method

Diagnose, question, master — whatever the subject.

Diagnose

A structured diagnostic maps what you already understand across every topic in your course or uploaded material, before any teaching starts.

Question

Your tutor asks before it tells, so you build the reasoning rather than copying a method. Wrong answers get a question back, not a worked solution.

Master

Every attempt updates a knowledge profile that decides what you should learn next, and shows where mastery is still thin weeks later.

A real exchange

This is what happens when you get it wrong.

A generic chat tool hands over the corrected working. Zetheo hands back the one question that exposes where the reasoning broke.

The answer is still there if you truly need it — but only after you have had a genuine attempt at finding it.

● Higher tier · Algebra · Solving quadratics

Zetheo

Solve x² − 5x + 6 = 0.

Student

x = 5 and x = 6

Zetheo

Try putting x = 5 back into the equation. What do you get on the left-hand side?

Student

25 − 25 + 6 = 6. So it doesn't work.

Zetheo

Right. So the two numbers you need are not the 5 and the 6 you can see. What do they have to do to each other — add or multiply — to give you −5 and 6?

Why not just use a chatbot

Uploading a PDF to a general AI gets you answers. It does not get you a tutor.

Three differences, stated plainly.

01

It withholds the answer on purpose

Socratic questioning is the default behaviour, not a prompt you have to remember to write. The tutor is built to make you do the thinking step.

02

Mastery persists between sessions

A chat ends and forgets. Zetheo keeps a knowledge profile per objective, revisits what is decaying and moves on only when the evidence says you have it.

03

Marking with real rigour

Work is marked against clear criteria — method, accuracy and notation — so nearly right is told apart from right, the way a careful examiner would.

Who it's for

Students, parents, teachers and schools each get their own way in.

Students

Start on your own material or the GCSE pathway and get going in a few minutes.

Start learning

Parents

See how the tutoring works and how structured progress is shared without exposing private conversations.

For parents

Teachers

Set material for a class, then see which objectives the group is weakest on before planning the lesson.

For teachers

Schools

Department-wide rollout, cohort reporting and safeguarding documentation for your designated lead.

For schools

Safety & privacy

Most of our students are children. We build accordingly.

Zetheo stays inside the material a student is studying. It does not wander into open-ended conversation, it does not use student work to train models, and a parent or teacher can see structured progress — not private tutoring conversations.

Scoped to study, by design

Conversations are bounded to the subject and objective at hand, with safeguards on both what a student writes and what the tutor replies.

Your work stays yours

Uploaded material and student answers are used to tutor that student. They are not used to train models and are not sold.

Visible to the adults responsible

UK GDPR principles shape the product, with consent-based parent access, a school view of structured activity and safeguarding documentation.

The art of learning, reimagined

On the GCSE pathway, content is built on AQA, Pearson Edexcel and OCR specifications, with progress tracked from the whole qualification down to a single learning objective.

Bring your own material and Zetheo derives the same structure from it — objectives, prerequisites and difficulty — so the tracking is just as precise on work no exam board ever wrote.
