Chat with PDF

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

Ask natural-language questions about your document
Get explanations based on the material you uploaded
Create notes, summaries, quizzes, and mind maps from the same workspace

How it works

  1. Upload your PDF or study document
  2. Open the AI Assistant
  3. 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?

Yes. It supports PDF, DOCX, EPUB, and TXT files for document-based study.

Can I turn PDF chat into quiz questions?
