How it teaches

Everything a great tutor does.For every child.

01

It knows her.

Pytha's teacher keeps notes like a real tutor: what she's strong at, where she slips, how fast she likes to go, what she loves. Every problem is pitched from those notes — and they grow richer every week.

  • Picks up exactly where she left off, on any device
  • Remembers last time — and says so
  • Notes deepen with every session

02

It reads her thinking.

A workbook only checks the answer. Pytha reads how she got there. Equivalent answers are never marked wrong, and when her reasoning is sound, her level is safe — even if the final number slips.

  • ½, 0.5 and 50% — all correct
  • Sound reasoning protects her level
  • Never shamed. No red ink.

Same meaning? Any way is right.

It lets her earn it.

Progress isn't filled by the clock. Every stage has six slots, and a slot only fills when she solves on her own, first try. Six on her own, then a short test — and she moves up because she proved it.

  • Hints are always okay — the slot just waits
  • Stage test: 4 of 5 to move up
  • Unit test: 8 of 10

It writes to you.

After every session, a note from the teacher: what she did today, where she got stuck, what was genuinely good — in plain, warm words and in your language. Sentences, not statistics.

  • Written in your language — not translated
  • Specific, encouraging, never shaming

Mia's session report

Robin · Mia's teacher

Thu, Oct 2 · 6 problems · Free Study · 24 min

Here's how today went.

Mia solved six problems on adding fractions. At first she added the bottoms too, but once she wrote “common denominator first” in her own working, she got every one right. She's practicing unlike denominators now — and getting quicker.

  • Nailed: common denominators
  • Working on: unlike denominators
  • Tricky: added the bottoms once — then caught it

In her own words: “I make the bottoms the same first.”

— Robin

Written in each language — not translated.

Behind every problem

One child.A whole teaching team.

Your child sees one warm teacher. Behind them, a team of AI specialists does what a great school does — each with one job, none of them cutting corners.

The teachers

Four teachers.Four personalities.

Pick the teacher your child clicks with: a high-energy coach, a gentle guide who leaves room to think, a storyteller who turns problems into adventures, or the warm classic. Whoever they choose, difficulty, grading and tokens stay exactly as fair.

Warm and steady — the teacher who has known you from day one.

Full coach energy. Every problem is a rep, every win gets a roar.

Soft-spoken and curious. Leaves room to think — never rushes you.

Every problem is a little adventure — with sparkle and plot twists.

Wanted: a teacher

  • Takes it slow
  • Talks soccer
  • Smiles if I'm wrong
Coming soon

Design a teacher together

Soon you and your child can write a “teacher wanted” note — and meet the teacher it becomes. Your voice, the same standards.

The Cosmos League

From the Moonto the Cosmos.

Every Monday, a fresh race in a room of up to ten. Ranked by the tokens earned that week — effort, not grade level — so a hard-working child at any level can win the week.

Tokens & rewards

A gift foryour child's effort.

Tokens turn into real rewards that you choose and approve — movie night, a new book. No in-app purchases. No cosmetic shop.

Fair by design

  • Harder rungs pay more

    8 → 18 tokens a correct answer, from rung 1 to rung 5

  • Hints are fine — just cheaper

    each hint takes 4 off a correct answer

  • Good thinking pays

    +6 even when the final answer misses

If only correct answers paid, a child would pick easy problems all day. Pytha makes reaching for the hard thing the better deal.
