Questions to documents and links to fragments 4.20 / 5 [Directory score](https://instain.ru/en/ai/chatpdf/#editorial-rating) [Official website ](https://www.chatpdf.com/) Answers questions about uploaded PDFs and links to passages in the documents. ![ChatPDF site with file uploading and document format selection](https://instain.ru/assets/images/chatpdf-screen-c5a811482552-1200.webp) ChatPDF home page with a document upload control. [Open the source ](https://www.chatpdf.com/ru) ## Ask a question to the document ChatPDF starts a conversation about an uploaded document. Citations in its answers take you to the relevant PDF passage. For a first pass through a manual, find the section on resetting settings, open the cited page and check which models it covers. The service allows you to organize files into folders and discuss several PDF in one conversation. To ensure that the conclusions are not mixed, specify the names of the files in the question. ## Compare the two versions of the instructions In this exercise, compare an old and a new set of instructions for returning school equipment. Upload both and ask which deadline changed and when the exceptions apply. Ask for a source for each condition. Open the citations and read the surrounding paragraphs. A restriction may be on the next page. If there are many tables or scanned pages in the PDF, first check that the service extracts the right numbers and signatures. It is more convenient to start with one well-known example and compare the answer with the original. Linking to a page makes it easier to reconcile, although the text of the answer can combine the correct data with the wrong conclusion. ## How to get access The site has a free mode and a Plus subscription. You need an account to save your history. The developer documents a separate API for uploading PDFs and querying a selected source. When choosing between web chat and the API, check processing limits and whether you can share your files with the service. ## Suitable tasks - Compare conditions in two PDF - Find a section of the instruction - Check the answer for links to pages Features ## Strengths - Go to the source of the answer - Discussion of multiple files in one conversation Things to consider ## Limitations - Citations and conclusions require separate verification - Scans and tables should be checked separately ## Selection and conditions Free access Yes Trial period Not confirmed No sign-up required Not confirmed Russian interface Not confirmed Local installation Not confirmed API Yes “Not confirmed” means there is not enough information.
