An AI chat PDF tool built for academic use: upload a PDF or TXT file, paste text, or load a direct link, and ask anything about it - summary, motivation, method, results, and free-form follow-up questions - with the document and the answers side by side on the same page, in your language.
The questions every reader asks are one click away - summary, motivation, method, result, and a review in simple words - and any free-form question can be answered in a dozen output languages, with dark mode and a phone-friendly layout built in.
Save documents to your Research Library with notes, tags, and a reading status; saved dialogs are restored whenever you reopen a paper; and the reader is one click away from every paper in your digests. For details, read how the AI academic reader works.
