§ 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.

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, 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.

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 and individuals who take the platform thesis seriously. Subsidized credits, direct founder access, prioritized request and handheld product ideation - in exchange for shaping how the layer learns and evolves.

Note: this form is not for students looking for a subsidized Verdict plan.

  • 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)
