ChatPDF
It's like ChatGPT, but for PDFs.
Drop a PDF, doc, slide deck, video or website link and start asking questions. Cited answers, summaries and translations in any language — built for students, researchers and professionals.
Why this product exists.
Skimming a 40-page paper to find one figure or claim wastes the afternoon — and you still miss context.
Generic chatbots hallucinate page numbers and quotes. You can't trust an answer you can't verify.
Legal contracts, financial reports and product manuals bury the answer five hundred pages deep.
Critical papers are in Japanese, German or Mandarin — translating manually breaks flow.
What ChatPDF delivers.
Drop a PDF, Word, PowerPoint, Markdown, text file, video or URL. Ask in plain English and get an answer.
Every response links back to the exact page. Click a citation and the side-by-side viewer scrolls to it.
Group related PDFs into a folder and ask questions across all of them in a single conversation.
Upload in one language, ask in another. Summaries pull the key insights so you don't read everything.
From chaos to clarity.
