Recorded walkthroughs of the platform.
The AI teaching IDE walked end to end on the most-enrolled coding project in the catalog: a price-time-priority order matching engine inspired by Citadel Securities. A Socratic tutor and a scripted student argue through the actual code while the editor highlights the exact lines under discussion; understanding is checked in-line with multiple-choice, free-form, and write-the-code-yourself questions graded by the tutor; a wrong answer gets called out and retried; and the learner can interrupt at any time to ask the tutor anything, grounded in the real files. Closes on the built-in narrated voice-over and the XP ladder. Narrated.
The same tutor teaching a no-code build: a Zapier AI agent that watches an inbox, classifies every email, enriches the lead, logs a CRM row, and drafts the reply — while a human approves every send. The workspace becomes the tool being learned: a live inbox, the agent's plain-English instructions run example by example, a CRM sheet that fills itself, the reply playbook highlighted like a marked-up document, and the Zap field map where one wrong mapping runs clean on the wrong data — the silent-failure trap, demonstrated and then fixed. Ends with the drafts reviewed by a human and the project completed. Narrated.
A technical flight simulator for a real on-call incident, worked end to end. At 15:00:00 a hot cache key expires; one second later the page fires — DB CPU pinned at 100%, the connection pool exhausted at 500/500, every request timing out. You read the page before touching anything, find the flaw that was always in the cache-aside read, catch an AI assistant proposing two fixes that would make it worse, rank four recovery actions by blast radius, take the smallest safe one, verify the symptom (not the vibe), make the fix durable with a fleet-wide single-flight lock, and close with the postmortem: the structural fix, the operational rule, the guardrail. Ends on the verified completion certificate. Narrated.
