This is the product
Bea teaches face-to-face
Every lesson is a live coach session: Bea explains, puts worked examples on her board, checks understanding, and reacts to what the student actually says. Choices, teach-backs, and mastery checks — zero slide-deck theory, zero typing drills.
Shown here: Train, Test, and Confusion from the 6–8 AI Investigators pathway — real session, real progress bar, Bea mid-lesson.
Coach session
Bea's board, live transcript, and session progress inside a real unit — captured from the running app.
Inside the app
Real screens from the running product — student side, teacher side, and the lab bench.
12 labs that teach judgment
Browser-based, deterministic, runnable in one class period. Hallucination Hunter, Prompt Architect, Privacy Trail, System Tradeoff Studio and more.
Teacher dashboard
Class codes, unit assignments with due dates, per-student mastery, one-click grade export.
Student hub
Join a class, open assignments with Bea, track pathway progress, build a portfolio of lab evidence.
Coach-led sessions
Bea talks students through AI concepts face-to-face — choices, reactions, teach-backs. UGC tutor energy, not a textbook dump.
Spiral curriculum
K–2 through college pathways mapped to AI4K12 Five Big Ideas and CSTA AI Learning Priorities.
Interactive labs
Decision trees, classifiers, bias explorer, model cards, recommenders, neural net sandbox — hands-on, not chat homework.
Classroom ops
Teacher dashboards, mastery, educator PD, district-facing trust pages for procurement.
School-ready posture
FERPA/COPPA-aware design. Student data is not used to train foundation models.
Spiral curriculum, five through-lines
Humans & AI · Representation & Reasoning · Machine Learning · Ethical Design · Societal Impact — revisited at rising depth across every band, aligned to AI4K12 and CSTA.
Power-skill units teach what students actually use Monday morning: specs before prompts, hallucination triage, privacy rules, threshold tradeoffs, personal operator playbooks.

Try the demo district
The live app ships with a seeded demo district (Meridian K-12) and campus (Harbor College). Sign in as a teacher, assign a unit, then flip to the student account and run the lesson with Bea end to end.
