Why Summarize Your PDFs With AI?
Students spend an average of 15+ hours per week reading assigned materials. Lorea's PDF to summary tool cuts that time dramatically by extracting only what you need to know — key concepts, definitions, and arguments — from any document.
Unlike simple text extractors, our AI understands context and hierarchy. It knows the difference between a main argument and a supporting example, between a critical definition and background information. The result is a structured summary that actually helps you study.
Works with any subject: medical textbooks, legal case briefs, engineering manuals, language learning PDFs, and everything in between. Upload once, study smarter forever.
Frequently Asked Questions
How does the PDF to summary tool work?
Upload any PDF and Lorea's AI reads the entire document, identifies the most important concepts and arguments, and generates a structured summary. You get key takeaways, chapter breakdowns, and highlighted definitions — all in seconds.
Is the PDF summarizer free to use?
Lorea is generally free and covers a lot — you can create study worlds, quizzes, and more without paying. There is also a paid upgrade for advanced features if you need them.
What subjects work best with the AI summarizer?
The AI summarizer works with any subject — medicine, law, engineering, humanities, languages, and more. It adapts its summary style based on the content type, whether it's a dense research paper or simple lecture notes.
How long are the generated summaries?
Summary length scales with document length and complexity. A 20-page chapter typically produces a 1-2 page summary. You can also adjust the detail level from a quick overview to a comprehensive breakdown.
Can I export or share my summaries?
Yes. Summaries can be copied, downloaded as PDF, or shared directly with classmates. They're formatted for easy reading and can be used as study notes alongside your original material.
