What is PDF GPT?

PDF GPT lets you upload PDFs and chat with them using AI. You can summarize lengthy documents, find specific information, translate content, and get answers that include clickable page references. It supports over 90 languages and is used by more than 500,000 researchers and professionals.

To start, you upload your PDFs. Then you ask questions about the document. The tool reads the PDF and gives you answers with page citations and highlights, so you can verify the website. You can also upload multiple PDFs and search across all of them at once, or tag documents and chat with groups based on those tags.

It suits students, researchers, and professionals who work with long documents. The site mentions you can generate summaries, study guides, and presentations from your PDFs. It does not list specific limits, but you can try it for free and see what fits your workflow.

  • Confirm that PDF GPT supports the file types you need, since the FAQ mentions different file types but does not specify which ones.
