Phantom Study is free and runs on free-tier hosting — so it doesn't pay for any AI itself. There are two ways to build your study sets:
1. No account needed anywhere. Copy the prompt we give you, hand it to ChatGPT, Claude, or Gemini along with your lecture notes, and upload the file it returns. Free on every chatbot.
2. Bring your own API key. Paste an OpenAI, Anthropic, or Gemini key to generate sets right here in one click. Your key is stored only in this browser and goes straight to that provider — never to us.
If Phantom Study has helped your studies, consider supporting it to keep things running!

Every time you take the quiz, questions AND answer choices shuffle so you can't just memorize positions.

Fill in the Blank
Type-in-the-answer exercises force active recall — the most effective study technique backed by cognitive science.
