Under the hood

Three pillars. One math page.

This is the technical tour, written for parents who want the mechanism. The parent version of the same ideas is on the home page. The live subject is math. The engine is shaped so later STEM subjects can share it.

  1. Read the page. A photo becomes a line-by-line account of the working.
  2. Mark the break. Green for a valid step. Red for the first misconception and its fallout.
  3. Unblock, then record. A hint, or a person within five minutes, then a structured note of what happened.

Pillar 1 · Learning system

The notebook stays. The reading is multimodal.

Students work on paper so the derivation stays in their hands. They upload a photo or scan. A computer-vision pass reads handwriting, symbols, geometric diagrams, and — when those subjects open — scientific formulas.

The check is not “is the final number right?” The page is turned into a symbolic execution graph: a structured map of the steps. Each step is tested for mathematical equivalence, a legal algebraic move, a sound deduction, or a geometric reason. The graph isolates the first line where a theorem was misapplied or a calculation slipped.

What comes back onto the page

  • Green overlay on valid progress, red on the misconception
  • A hint aimed at that step, not a full solution dumped at once
  • A solution tree the student can open one move at a time
  • A short exercise chosen for the specific gap
  • A map onto GCSE, IGCSE, O-Level, or IP criteria

Today that map is mathematics: proof, spatial reasoning, and calculus where the syllabus asks for it. Science content is in the design of the reader. It is not a course you can start.

Pillar 2 · Human triage

A person joins when the model should not guess.

Escalation is automatic when a step is a logical misconception, or when confidence in the reading falls below 85%. The specialist runs a live whiteboard intervention aimed at about five minutes: long enough to repair the idea, short enough that the student returns to their own page.

The launch tutor network is PhD-level engineering tutors based in Indonesia, the Philippines, Morocco, and India. Their hours cover after-school time in Singapore and the UK. Families do not have to arrange that coverage. A local success manager in Singapore or the UK is the person a parent speaks to.

When many students are stuck at once, extra specialists are added through WRK.com so the five-minute target can still hold.

Neuro-Flex, the teaching rules

Every intervention follows the same learning-science constraints. We call that set Neuro-Flex.

  • Focused work on the broken step, then a short diffuse pause before the next question
  • Chunking a long derivation into pieces that can be held
  • Active recall: the student does the next line, the specialist does not
  • A time box, so help stays a rescue and does not become the homework
  • A concrete metaphor when the abstract move will not stick

Pillar 3 · ANIMA

Every human intervention becomes a record the next hint can use.

ANIMA is the protocol for a live help session. It turns an unstructured whiteboard conversation into four fields a model, and a parent, can actually read.

  1. ContextThe exam, the question, and the page as it stood.
  2. Inferred misconceptionThe idea the specialist believes is slipping.
  3. Human actionThe hint, question, metaphor, or worked move they used.
  4. Verified outcomeWhether the student could take the next step themselves.

The specialist is also an annotator. They tag the cognitive trap, label multi-step errors, and confirm whether the vision pass read the handwriting correctly. Those labels are how common slips become hints the system can give without a person.

A person still joins when the block is real or the reading is under 85% confidence. What changes over time is how many ordinary errors are caught before that escalation. Parents see the outcome as sharper hints and a syllabus view, not as a black-box score.
