Twelve platforms, one design law: the human stays anchored.

Every ERTC platform is a running experiment in Human Agency Anchoring — deployed, instrumented with xAPI, and in use with real learners.

AlwaysAI

Assessment

AlwaysAI reimagines assessment for the AI era rather than banning it. Its dual O×A framework scores every task twice: on the outcome achieved, and on the quality of AI collaboration across six dimensions, turning transparent multi-session learning journeys into measurable provider-agnostic skill.

React · Node · GCS · xAPI/LRS · 11 LLM providers

myKE · Knowledge Explorer

Inquiry

myKE turns any topic into an explorable, AI-generated knowledge map. Instead of handing over answers, it drives learning through Socratic questioning and stealth assessment, silently tracking 158 learner behaviours while Wonderment agents surface paradoxes that spark curiosity and reward learning from failure.

VHS · Virtual Human Simulation

Agents

VHS builds virtual humans with genuine inner lives, orchestrating many psychological agents that perceive, deliberate, and form coalitions before every response. Used for behavioural research, training, and consultation, it exposes the full internal reasoning behind each decision through a transparent peek-into-the-brain view.

Scriptorium

Writing

Scriptorium is a rubric-first writing studio where evaluation quality comes before output. Every rubric must pass twelve psychometric validation gates and over two hundred automated checks before grading any student, ensuring fair, defensible, scientifically rigorous assessment across one hundred seventeen writing genres.

Write2Learn

Authorship

Write2Learn is an AI writing studio that keeps the student as author. Rather than tracking who typed it, it measures defensibility, whether you can justify your work, using colour-coded feedback and an AI committee that questions each draft until ownership is earned.

SIAIS

Architecture

SIAIS is an orchestrator that automatically selects teaching strategies from each learner's profile and tracks mastery through logged interactions. It separates tutoring logic, learner memory, and governance into modular layers, maintaining auditability through an append-only xAPI event log without unanchoring the human.

UALS

Adaptive

UALS is an adaptive platform coordinating one hundred agents across two educational philosophies, curriculum-based and competency-based. It delivers personalised instruction through three modes: self-paced exploration, AI-guided tutoring, and scenario-based assessment, instrumented end-to-end so every step becomes analysable evidence while humans stay anchored.

15SATA

Psychometrics

15SATA is an assessment engine that generates Select-All-That-Apply questions across fifteen formats while capturing learner behaviour, including hesitations, revisions, and confidence ratings, under psychometric discipline. The result is diagnostic insight into how learners reason, not merely whether their final answer was right.

15KE

Inquiry

15KE transforms a single concept into fifteen interactive formats across three categories. It records every learner action as standardised xAPI statements and analyses engagement patterns, helping educators, researchers, and students explore what is known through many complementary lenses rather than one path.

Q2L · 以问致学

Inquiry

Q2L makes the learner the questioner rather than the answerer, treating the act of asking as the assessed skill. In this Question-to-Learn environment, behaviour telemetry captures how inquiry unfolds, and every question a learner poses becomes evidence of the understanding behind it.

Classic Cognitive Experiments

Experiments

Onset is a web-native studio that converts fifty-five classic psychology paradigms into version-controlled JSON specifications. Researchers design rigorous experiments once and deploy them across lab, browser, mobile, and scanner environments, with frame-locked sub-millisecond timing, adaptive staircases, and live multimodal data streaming throughout.
