Built for my daughter. Might be useful for yours too.

How it works

Your photo is sent to OpenAI Vision for OCR, then the extracted text goes through a multi-agent LLM pipeline that generates five question types: flashcards, single-choice, multiple-choice, fill-the-gap, and sorting.

Three study modes: Flashcards (flip), Quiz (immediate per-question feedback), Test (scored at the end).

You bring your own OpenAI API key — stored in localStorage, used only to call OpenAI directly from your browser.

Getting started

Node 18+, a Neon Postgres database, a Google OAuth client, an OpenAI API key.

git clone https://github.com/abi83/prepify.git
cd prepify
npm install
gcloud auth login  # secrets are fetched from GCP Secret Manager automatically
npm run dev

Open the app → Settings → paste your OpenAI key.
