How it works

Talk it out. Watch it drawn. Jump in when you're lost.

Speak your problem

Hold space and just talk — "why does the chain rule work?" Snap a photo of the question that stumped you. No typing equations like a robot, no perfect phrasing required.

Watch it draw

As the tutor talks, the whiteboard fills in — equations line by line, a parabola taking shape, a triangle labelled as it's mentioned. You're not reading a wall of text. You're watching someone think it through with you. Imagine hearing "let's find the derivative" while watching "dy/dx" appear on the board in real time.

Interrupt freely

Lost at step three? Cut in mid-sentence — "wait, where did that come from?" The tutor stops, scrolls back to that exact step, and explains it a different way before moving on. Just like a real one would.

Built for how you learn

Not a calculator. Not a search box. A thinking partner that stays until you get there.

Built to teach, not just answer

Walks the logic with you step by step — so you leave understanding, not guessing.

Find anything, instantly

Jump back to last week’s parabola or that stuck integral without digging through notes.

Follows your curiosity

Ask “but why?” as many times as you need. It stays until the idea actually sticks.

Built for the moment you're stuck

Beta is still opening. Until then — this is who Mathlon is for, and what the free demo is meant to feel like.

StudentsExam week, midnight, still stuck

The problem that won't click and no tutor free at 11pm. Talk it out — Mathlon draws every step until it does.

RelearnersComing back after years away

Algebra from a decade ago doesn't have to mean a textbook alone. Ask out loud. Interrupt. Go as slow as you need.

The curiousWhen “why?” keeps coming

Not an answer dump — a conversation on a shared whiteboard, so you leave understanding the move, not just copying it.

Frequently asked questions

An audio-visual math tutor. You talk through a problem out loud, and Mathlon explains it back while drawing every step on a shared whiteboard — equations, graphs, diagrams, the lot. It's built to teach the way a good human tutor does, not to spit out a final answer and leave you to reverse-engineer it.
Try Mathlon free first — a short guided demo, no credit card, no signup. If it clicks for you, Beta access is $7/month, locked in for as long as you stay subscribed. That price won't be this low once we're out of beta.
Hold the space bar and talk like you would to a person — "I don't get why this integral works." Mathlon hears you, thinks, and replies out loud while the whiteboard fills in alongside the explanation. You can cut in any time; it'll stop and back up to wherever you got lost.
Khan Academy is pre-recorded lessons made for everyone. Mathlon is a live conversation made for you — it reacts to your exact question, in your words, at your pace, and draws the answer in real time. Less watching, more doing it together.
