LightPDF lets you chat with documents instead of scrolling endlessly for answers. Upload PDFs. Word docs. Spreadsheets. Even scanned files work. Ask questions in plain English and the AI responds with GPT-4. It shows exactly where each answer came from with clickable references. Multiple documents at once — beats opening dozens of tabs.
Picture a compliance officer reviewing contract amendments. They upload all related files and ask "What are the key changes to payment terms?" LightPDF pulls relevant sections from each document and cites sources. Over 100 languages supported. Information comes out as markdown tables or formatted notes.
OCR works on scanned documents. Chrome extension available too.
You'll need internet since it's web-based — might slow you down if you work offline frequently. The AI generates summaries and extracts data into tables, saving hours of manual work. Business professionals dealing with document-heavy workflows find this faster than traditional search methods.
Students and researchers upload research papers and textbooks to get quick explanations of complex topics. The footnote system makes verifying information sources easy, which matters for academic work. You can also feed it webpage URLs if you need to analyze online content alongside uploaded files.
