SINGAPORE · 2026 · STUDENT INTELLIGENCE LAYER

Build
with VOSE API.

Student intelligence as infrastructure. VOSE is the data layer that educational AI should have been built on from the start — portable identity, open citation chunks, and four endpoints any team can build a tutor on top of.

§ 01 — Surfaces

Seven products,
one intelligence layer.

Most of these are imagined possibilities, things any small team could ship in a weekend on top of VOSE. One is real, live, and you can sign up for it today. The reference deployment is named Verdict.

§ 02 — The thesis

Education should be open source.

Stripe didn't make payments. It made the layer underneath, so a thousand teams could.

Auth0 didn't make logins. It made the layer underneath, so a thousand teams could.

Twilio didn't make conversations. It made the layer underneath, so a thousand teams could.

Now apply the same pattern to student intelligence.

VOSE is the portable, queryable, citation-grade record of how a learner actually learns. One identity across every tutor they use, with the chunks visible and the policy theirs.

Read the full philosophy →

PAYMENTS = STRIPE

Card numbers, fraud, compliance — done once, used by all.

AUTH = AUTH0

Passwords, sessions, social — done once, used by all.

STUDENT INTELLIGENCE = VOSE

Profiles, mastery, citations, policy — done once, used by all.

§ 03 — What VOSE does

Four endpoints.

Each is a contract, not a feature. VOSE isn't a UI, isn't a content library, isn't an LLM.It's the layer between the model and the learner that has been missing.

POST/teach

— deliver content with audit

Stream concept exposition with full citation chunks attached. The model can't pretend to know what it doesn't; every claim points back to source. Returns the chunks alongside the answer, not hidden behind a "powered by" footer.

POST/guide

— socratic teaching

Just-in-time teaching, not front-loaded content. The learner attempts before they're taught; the response delivers the concept at the moment of cognitive readiness. Verdict's Reverse Drill is built on this.

POST/practice

— generate items

Spawn calibrated practice items against a learner's current proficiency curve. Items are tagged by skill, by source chunk, by failure mode — so failure becomes signal, not noise.

POST/assess

— mastery + audit

Submit an attempt; receive a graded verdict, the rubric trace, and an updated mastery vector. Every grade is reproducible from the chunks — citation-grade auditability isn't a feature, it's the whole point.

Citation specimen

The chunks are visible.

Every answer carries the source it stood on. No interface clarity excuses for hiding what the model saw.

CHUNK · /teach response§ 4.2.1 · price-elasticity-of-demand.md

A good is said to be price-elasticwhen the percentage change in quantity demanded exceeds the percentage change in price (|PED| > 1). For example, demand for restaurant meals tends to be price-elastic; consumers can defer or substitute.

REFERENCE DEPLOYMENT · LIVE

Verdict.
VOSE, deployed.

Singapore A-Level Economics, built by a 19-year-old sitting his own A-Levels in November 2026 as a private candidate. Reverse Drill. Source-tagged retrieval. Open citation chunks. Mode wheel. Tone presets. Built on VOSE so we know the platform's contracts hold under load.

Explain why the PED for restaurant meals is likely greater than 1.

Restaurant meals are discretionary substitutes — consumers can cook at home, defer, or switch venues. Time horizons compress — ▍

§ 04 — Build on VOSE

Build your first VOSE-powered tutor in 30 minutes.

We do the student intelligence; you do the UX. No more rebuilding portable identity, citation infrastructure, or mastery vectors from scratch in every weekend project.

Out of the box

§ Identity

Portable VOSE ID

OAuth 2.0 + OIDC. Sign in with VOSE across every tutor in the ecosystem.

§ Persistence

Mastery profiles

One learner record, queryable from any surface. Carries failure modes, not just scores.

§ Audit

Citation primitives

Every answer carries chunks. Every chunk carries provenance, weight, and a stable id.

§ Intelligence

Collective signal

Trapdoor mode now; intelligence flips on as the pilot cohort populates the corpus.

§ 05 — Pilot

Join the build.

VOSE's pilot program is built for the first hundred teams that take the platform thesis seriously. Subsidized credits, direct founder access, prioritized requests — in exchange for shaping how the layer evolves.

01Subsidized free tier credits for early integration
02Direct founder access for technical questions
03Prioritized feature requests from the build queue
04Discord access to the builder community
05Early access to features before public release
06Premium pilot bonuses (TBD, per pilot)
