Chat with PDF by Copilot.us

What is Chat with PDF by Copilot.us?

Chat with PDF by Copilot.us is an AI app for reading documents through conversation. You load PDFs or Google Drive documents, type a question, and get an answer along with a reference to where in the original file the information sits, so you can check it without paging through the document. You can highlight a portion of the text and ask for a short summary, or write your own instructions to pull out exactly the detail you need. It is one app inside the Copilot.us collection from bestaiapps.co, which also lists a summarizer, a YouTube SEO helper, an invoice app and a PDF form filler under one subscription. Students and researchers use it to get through long papers, and analysts use it to query reports. The product pages do not show a price table, and the terms describe recurring monthly fees for paid services, so check Copilot.us for current pricing.
