PAIDEIA is a local-first Claude Code plugin for students who study from messy course PDFs, homework, solutions, and handwritten mistakes. Instead of teaching an average syllabus, it builds your course-specific exam graph: PDF-to-Markdown ingestion, solution pattern extraction, homework-density weighting, OCR grading, weakmaps, drills, mock exams, and cheat sheets. Every artifact stays on disk as editable Markdown.
