While building my own medical edtech product, I wrote the same "text → quizzes + flashcards + review schedule" plumbing at least three times. Every new feature, same chore: call an LLM, parse the output, schedule the next review, and avoid paying twice for the same input.
So I cleaned it up into one small API — QuizForge:
-
POST /generate— text, a URL, or a PDF → MCQs, short questions, flashcards (in the language you ask). -
POST /grade— score a free-text answer 0–5 with feedback. -
POST /review/next— SM-2 spaced repetition, the next due date for a card. Two things I cared about: - Don't pay twice. Identical input is served from a content-hash cache — no second LLM call.
- Make it testable. The LLM is injected, so the whole thing runs offline — 29 tests, no network. It's live as a hosted API with a free tier to try it, and there's a self-host version (Docker, bring your own LLM key) for people who'd rather run it themselves. Full disclosure: I build with AI assistance (I pair with Claude), and I'm a solo founder — a maxillofacial surgeon who got into shipping software, not a team. Support is email-only, but I answer everything. Happy to dig into the design — and I'd genuinely like to hear how you'd price the hosted version.
