with VOSE API.

Vectored Open Source Education (VOSE) is the data and identity that follows your intellectual journey cross-application and makes every instance smarter. Every user, plugin, production app compounds the intelligence API.

§ 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. The reference deployment remains documented, but new access is closed. It is named Verdict.

§ 02 - The thesis

Education should be open source.

The burden of all Edtech applications currently is that everything exists in a closed silo.

Stripe didn't make payments, Auth0 didn't make logins, and Twilio never made conversations.

We don't just offer a consumer application - we offer the infrastructure that makes the education ecosystem truly interlinked.

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 - all tagged via logic gate understanding.

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 just a feature, it's our entire thesis.

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.

Verdict.
VOSE, demonstrated.

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.

QUESTION · DRILL 04

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 - ▍

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.
