Portfelim

Teachers upload material, pick question types, difficulty and language, and a multimodal LLM returns a strict-JSON exam plus answer key they edit in a rich TipTap/KaTeX editor before exporting to PDF or DOCX; the same AI grades open-ended answers and generates study materials. Built as a Laravel 13 API (Sanctum, PostgreSQL, queued jobs) with two Next.js 16 front-ends – the app and a separate marketing site.
