Erudex
2026
AI-powered lesson plan generator with chat interface
Overview
Erudex is an AI-powered learning platform that turns natural language requests into structured, pedagogically ordered lesson plans. The interface is a split view: a docs panel on the left for navigating hierarchical lesson content (sections and subsections) and a chat panel on the right for requesting new lessons or refining existing ones. The AI always proposes a full lesson plan before anything touches the database, so you can accept or decline before committing.
It is built with Next.js 16 and the Vercel AI SDK, uses Claude Haiku for lesson generation, and enriches content live through Brave Search over the Model Context Protocol. Lesson plans, sections, items, and chat history are all persisted per user in Supabase PostgreSQL with Drizzle ORM. The whole project was developed spec-first with Spec Kit: every feature is designed, planned, and contracted in the specs/ directory before any implementation.
