Chat with PDF — Ask Any Question About Your Documents
Stop scrolling through 200-page textbooks. Upload your PDF to Geleza and ask any question — get precise, sourced answers in seconds. Powered by AI and vector semantic search, PDF Chat finds the exact relevant passages even when your question uses different words than the document.
How PDF Chat Works
When you upload a PDF, Geleza automatically extracts the text, splits it into intelligent chunks, and generates semantic embeddings stored in a vector database. When you ask a question, we find the most semantically similar passages using cosine similarity search — then send those passages to the AI to compose a clear, cited answer.
Perfect for Academic Research
PDF Chat is ideal for research papers, textbooks, legal documents, financial reports, and study guides. Students use it to quickly locate specific facts in thick textbooks, lawyers use it to scan contracts, and researchers use it to extract key findings from journal articles.
Better Than Ctrl+F
Traditional search finds exact words. AI semantic search finds meaning. Ask 'What causes inflation?' and it will find passages discussing monetary policy and supply/demand — even if those exact words don't appear together. This makes PDF Chat dramatically more useful than text search.
