Is QuizLLM (NEW: Start Free!) safe?

Clean risk

QuizLLM sends quiz questions, answer choices, and optional uploaded document text to its backend or selected LLM APIs.

On supported quiz sites, QuizLLM reads current questions and answer choices from the page or WebSocket messages when generating an answer. If a user has backend access, it sends those details, optional uploaded file content, email, and access token to the QuizLLM backend; otherwise it sends the prompt to the user's configured OpenAI, Anthropic, or Google API.
