The Moat — Continuity Engine

Every chat turn builds a context bundle — teacher rules + progress snapshot + current lesson content + last 20 messages — injected as system prompt. Progress persists in Postgres per user, so "Continue" always resumes exactly where they left off. No other competitor in this space has this — they all start from scratch every chat.

Overview

Built on Next.js 16 + Supabase + Vercel AI SDK with DeepSeek V4 Flash as the AI teacher. 14 modules and 95 lessons are seeded into the curriculum. Terminal labs use a companion devops-lab CLI that runs real Linux commands locally and the server re-verifies command + output evidence before awarding XP. Notes are markdown per user with Obsidian sync (Pro-only export). Monetized via Razorpay with a Stripe-ready provider abstraction: Free ₹0, Starter ₹199/mo / ₹1,999/yr, Pro ₹499/mo / ₹4,999/yr.

What Stands Out

• Continuity engine: AI teacher resumes exactly where the user left off
• 14 modules / 95 lessons, full curriculum seeded
• Terminal labs with real command grading via devops-lab CLI
• Notes notebook + Obsidian sync (Pro feature)
• Monetized from day one (Razorpay, 3 tiers, Stripe-ready)
• Per-user chat sessions with RLS, auto-titled
• DeepSeek V4 Flash AI teacher, platform key only
• Admin panel: edit pricing/model/teacher-rules live
