A product in production
The stack runs in production, not in demos — so far at closed-beta scale. Proof that the technology lives beyond the slides.

StudyNinja Production
A preparation platform for school students: a subject knowledge graph, gap diagnostics and selection of the next learning step. It runs in production — so far at closed-beta scale, not as a demo.
The problem
Technology in presentations is easy to claim and hard to check. What is needed is a product in production, where the stack runs not on slides but in real operation.
Why existing solutions fail
Demos and slides do not prove that a technology works in operation; only a product in production shows that — even at closed-beta scale.
How it works
We show the interface and the learning flow: the gamified “Ninja Path” roadmap, the GRR micro-lesson (I-do/We-do/You-do/Reflection) and the knowledge map. The framing is narrow — “learning platform”; the question-selection rules and the mastery/confidence/difficulty weights are not disclosed.

Use cases
Diagnostics and the next step
A subject knowledge graph, gap diagnostics and selection of the next learning step — as product behaviour, without disclosing the selection rule.
Evidence
“Ninja Path” — a gamified roadmap on a public mock route, no login needed
The public route /roadmap-flow-mock shows the roadmap interface without a session — it can be captured headless right now.
Reproduce: vite UIKit on :5173 → /roadmap-flow-mock
GRR micro-lesson: I-do / We-do / You-do / Reflection + math pad
We show the learning flow (the lesson phases), not the question-selection rule.
3D “knowledge cone” — the knowledge map (interface)
An interactive knowledge map with orbit/click; the showcase displays a stylised sample, not real weights.
Integration
A live product at studyninja.ru — a showcase that the stack runs in production; the scale is a closed beta.
