The problem

Teachers and trainers spend hours writing quizzes from source material. Most of that time is mechanical — reading, picking facts, phrasing distractors — not pedagogy.

What I built

An agentic web app that ingests a PDF or raw text and produces a ready-to-use quiz in seconds. The agent chunks the source, identifies testable facts, and generates well-formed questions with plausible distractors.

Stack & decisions

  • Agents: multi-step pipeline — extract → classify → generate → validate. Each step is its own agent call so failures are isolated and debuggable.
  • Backend: FastAPI for the quiz generation API.
  • Frontend: Next.js app for upload, preview, and export.

Outcome

Cut quiz prep from hours to seconds on real educator workflows. The separation-of-concerns agent pipeline made it easy to tune one stage (e.g., distractor quality) without regressing others.
