Your personal Olympiad coach.
Available 24/7.

Starting with primary-school students who know BODMAS (the order of operations) and are comfortable with basic arithmetic. Older students can go much further. Curiosity matters more than a competition record.

Yes. Adults are welcome to explore the preview, whether they are returning to mathematics, strengthening their understanding of physics or learning to reason about algorithms. The focus is building foundations through challenging problems and personal guidance.

No Olympiad experience or “gifted” label is needed. Start with basic arithmetic, BODMAS and a willingness to try an idea. Your child doesn’t need to arrive with all the answers.

Absolutely. Problems range from accessible puzzles to demanding Olympiad-level challenges. Experienced learners can explore elegant proofs, surprising connections and problems that take more than a familiar formula.

StemOverflow complements school with focused practice in mathematical, physical and algorithmic reasoning. Your child tackles unfamiliar problems, tests ideas and explains why a solution works. The focus is depth of understanding, beyond syllabus coverage and exam technique.

Erdős explores mathematical patterns, geometry, counting and proof. Landau starts from school physics and helps learners build physical explanations. Neumann explores algorithms, correctness and efficiency, with ideas expressed in words or pseudocode.

Learning is in English, with the choice to type or speak and edit before sending. We want StemOverflow to be as inclusive as possible. Please write to us about what would help your child, so we can make the experience better for them.

Your coach can explain an unfamiliar concept and help you apply it to the problem you are working on. Our aim is to bring connected lessons, concept notes and practice together in self-contained tracks. Today’s preview lets you experience the problem-solving conversation.

A learner opens a problem, tries an idea and explains it. The coach responds to that reasoning in the context of the conversation. They can test examples, revise an argument, use a notebook and discuss why a solution works. The work begins with their attempt.

That’s a natural part of tackling something new. Your child can share a half-formed idea, ask for a hint or take a break. The coach responds with questions, nudges or brief explanations to help them find a way forward. There’s no timer and no race.

The coach is designed to explore different valid approaches. It follows your child’s reasoning, asks for clarification where needed and helps them explain why their method works. The discovery should belong to them.

In the practice room, supported browsers offer editable speech input: speak, check the written version and send when ready. Recording and transcription do not work reliably in Android browsers yet. Typing is always available, and optional read-aloud works on supported browsers.

Younger learners may appreciate help getting comfortable with the problem and the controls. Encourage them to explain an idea in their own words, then give them room to explore. A useful parent question is: “What have you tried so far?”

Your child explains why their solution works. The coach follows the argument, asks about gaps and checks the reasoning before marking the problem complete. A correct answer is the beginning of that conversation; the explanation is what gives it substance.

Your child can continue to another problem or stay to explore the idea further. Their conversation and notebook remain saved, so they can revisit how they reached the solution.

Revisit the saved conversation, notebook, progress and help history together in the learning account. You can see the ideas your child tried, how their argument developed and where they needed a nudge.

Coach assistance and viewed solutions stay visible in the learning record. That gives context to each completed problem. If your child received help elsewhere, keep that in mind when looking back at their work.

Look for clearer explanations, more purposeful examples, willingness to revise an idea and less reliance on hints. The deeper test is whether your child can use an idea independently in an unfamiliar problem. Those are the habits we want to develop.

Try 15–25 minutes with one worthwhile problem, then adjust to your child’s energy and interest. A thoughtful attempt matters more than finishing a quota. Pause when needed and return with fresh eyes.

No. Ordinary language, examples and step-by-step explanations are welcome. Informatics focuses on algorithms expressed in words or pseudocode, not runnable programs. Paper can help with thinking; for now, the learner needs to describe that work in the conversation.

The interface works in a browser on a computer, tablet or phone. AI coaching needs an internet connection. A microphone is optional, and recording support varies by browser. There is no separate app to install.

Yes. Saved conversations and notebooks belong to the signed-in Google account. Return with the same account to resume. Unsent drafts may remain only in that browser, so save notebook work before switching devices.

Each account keeps one learning record. Separate records are important so each child’s conversations, progress and help history stay their own. Shared family profiles are not available.

There’s no need to create an account for your child now. We’ll share the family sign-up details when student enrolment opens. Google sign-in is available for the preview.

The coach is designed around checking reasoning and encouraging your child to question ideas, including its own suggestions. Responses go through quality checks, and you can flag anything that seems off to help us investigate and improve. AI can make mistakes; the focus stays on reasoning your child can explain and defend.

Your child works with Erdős for mathematics, Landau for physics or Neumann for programming. These are StemOverflow’s AI coaches, designed for guided discovery. Each responds to your child’s ideas throughout the conversation. You can share feedback on individual replies to help us improve the experience.

Conversations, notebooks, progress and help history are saved so you can return to your work. Private diagnostic records help us investigate issues and improve coaching. External AI services process conversation context and optional speech input. Notebook entries are not sent to the coach. Google sign-in uses an account identifier and email, without access to Gmail or Drive.

Speech is sent to a transcription service and turned into text for your child to check before sending. StemOverflow does not save the original audio recording. Only the text your child chooses to submit becomes part of the coaching conversation.

You can export saved learning work and reset a circle. Reset clears that circle’s work; full account deletion, including any separate reports and backups, is a different process and is not available through that control.

You can try a coached maths problem without an account. It gives you a real conversation with Erdős, not just a puzzle to click through. The wider account experience is a preview; paid student enrolment has not opened.

The goal is to become the person who can solve the problem. StemOverflow centres the experience on your child’s attempts, a coach that responds to their reasoning and a record of how they reached a solution. The discovery belongs to your child.

We’ll announce pricing with the enrolment details. No payment is required to explore the preview.

We’ll share trial options and subscription terms before paid enrolment opens, including renewal, cancellation and refund details. There are no charges or subscriptions in the preview.

You can explore the current coaching preview. An account includes 50 free coach replies; paid plans are coming soon.
