Your ultimate agentic
AI study companion.

ChatGPA knows your child's learning history, spots where they keep getting stuck, and proactively guides them forward — accurate grading, personalized practice, and real concept mastery, all in one place.

For students and families · Your data stays yours

Built around how students actually learn

Not just a homework tool — a companion that grows smarter the longer your child uses it.

🎯

The most accurate grader

Snap a photo and get every question graded precisely — plus a full explanation of what went wrong. We pick the best model for each job: GPT, Gemini, Claude, or ElevenLabs, whichever gives the most accurate result for that task.

📚

Your full learning archive

Every question, answer, mistake, and conversation is saved and builds a personalised learning profile. The learning agent uses your history to suggest exactly what to study next — tailored to your child, not a generic student.

💬

Conversational AI tutor

After grading, jump straight into a conversation — ask for more explanation on any question. Or explore any topic freely, and generate practice questions right from your conversation.

🔬

Feynman-based mastery

When a concept keeps going wrong, ChatGPA walks through it from first principles — the same method Nobel-winning physicist Richard Feynman used to actually understand things, not just memorise them.

📈

Progress you can see

A subject-by-subject learning curve that fills in as your child studies. Measurable improvement, tracked week by week — you'll notice it within a few sessions.

📋

Weekly & monthly reports

Parents get a short, readable summary of their child's activity, focus patterns, study habits, and general wellbeing — sent automatically, no setup needed.

🔒

Your privacy, protected

Conversations are end-to-end encrypted. We don't sell data or build advertising profiles. Your child's learning history belongs to your family — full stop.

How it works

A loop that builds on itself — the longer your child uses it, the better it gets at helping them.

1

Study and capture

Snap homework, ask questions, or talk through a concept out loud. Everything is saved to the learning archive.

2

Understand it properly

Get clear explanations — and if something keeps going wrong, the Feynman method kicks in to build real understanding from the ground up.

3

Get guided forward

ChatGPA uses your learning history to suggest what to practise next — not random topics, but exactly what needs work.

A small team, building carefully

We're a small team that wants ChatGPA to be genuinely useful — not just impressive to demo.

Who we are

ChatGPA is operated by a company registered in Hong Kong.

This site is for product information and early access. If you're a parent or educator, we'd genuinely love your feedback.

What we care about

  • Real understanding — we use the Feynman method because memorising answers isn't learning.
  • Privacy — end-to-end encryption, no data selling, minimal collection.
  • Honesty — early feedback from real families shapes what we build next.

A note on AI

The tutor can be wrong sometimes. We encourage students to question answers and use ChatGPA as a thinking aid — the goal is understanding, not outsourcing homework.
