147 lessons across 14 levels. JSON-driven content with 10 interactive section types (Quiz, FillInBlank, ClickMatch, TerminalPreview, etc.). Content authored manually, structured and validated with AI assistance. Each lesson is a standalone JSON file with metadata, sections, and completion criteria.

Personalized learning plans generated by Claude or Gemini. Students describe their background and goals, AI analyzes the full curriculum and builds a custom path highlighting priority levels and recommended lessons. Plans saved to DB and shown on dashboard.

Admin describes a theme hint, AI generates a full 14-token color palette for both dark and light modes. Colors validated against CSS hex/rgba patterns. Stored in DB, selectable by all users. Supports both Anthropic and Gemini providers.

Browser SpeechSynthesis API reads lesson content aloud. Admin-configurable voice, rate, pitch, volume. Per-section toggles (narrative, guideStep). Voice matched by name across browsers. Zero backend cost — no audio files, no external APIs.

Discussion categories (general + lesson-specific), threads with titles/bodies, replies, upvote/downvote voting, full-text search via PostgreSQL tsvector. Image attachments (client-side resize, base64). Content moderation pipeline on all user input. Feature requests via genie-themed wish system.

Real-time help system via Socket.IO. Students request help on specific lessons, peers can offer assistance and chat. Dual moderation pipeline: sanitizeForPrompt() for AI injection guard + moderateContent() for profanity and link spam.
