What it does

Chat with PDF is one of the AI apps on the copilot.us site, credited on the page to bestaiapps.co. It lets you extract information from, analyse and hold a conversation about several PDFs or Google Drive documents at once. You can select part of a document to get a short summary, or type your own instructions to get targeted answers. Each answer comes with a pointer to where it appears in the source PDF, so you can check it without paging through the file. Access is through a membership that covers many of the site's apps, and the page offers a 7-day free trial. No plan prices are shown.
