Chat with your PDFs and study documents
Upload a PDF, DOCX, EPUB, or TXT file and ask questions in plain language. Lumina helps you find key ideas, explain confusing passages, and turn reading into an active study session.
What you can do
How it works
- Upload your PDF or study document
- Open the AI Assistant
- Ask for explanations, examples, summaries, or follow-up questions
Common study workflows
Clarify a confusing paragraph in a textbook chapter before class.
Ask a research paper what its method, evidence, limitations, and conclusion are.
Review lecture PDFs by asking for examples, definitions, and likely exam questions.
Why use Lumina instead of a generic AI chat?
General AI chat can answer broad questions, but PDF study works better when the assistant stays connected to the source document. Lumina keeps the reading, chat, summary, notes, quiz, and mind map in one workflow.
Built for active learning
Lumina Study helps students and researchers move from passive reading to active study with document chat, summaries, quizzes, mind maps, notes, translation, and audio.

Does Lumina support files beyond PDF?
