Why PDF Copilot is your ultimate AI tool for working with PDFs

Detailed and context-aware responses

Imagine you’re reviewing a 200-page contract for your client. Instead of scrolling through endless sections, simply ask PDF Copilot, “What are the key client obligations in this document?” and it will not only give you a concise answer but also highlight the exact locations of those parts. PDF Copilot remembers your previous queries, so when you ask a follow-up like, “Does the contract have this clause?” it gives a contextually relevant answer based on your earlier conversation.

• Receive more elaborate answers that include thorough explanations, making the information easier to understand.
• PDF Copilot digests any changes in the document, allowing the chat to operate on the latest version of the document.
• Answer Formatting: From now on, answers fully support markdown formatting in text, including quotes and code segments.

More advanced features to enhance productivity

Stumbled upon an unknown term in the paper? Just choose this phrase, activate the context menu, and tap the ‘Explain’ action. PDF Copilot will provide a detailed explanation of the term right away. You can also use a contextual menu to get quick translations of specific terms, phrases, or text sections.

• NEW Contextual Actions: Get quick translations or comprehensive explanations by invoking the context menu on the document.
• Content references now include not only page numbers but whole text blocks inside the document view with visible highlighting.
• Interact with PDFs directly through chat: highlight and underline text within the PDF that is being referenced.

Intuitive and accessible interface

To help you work quickly with PDF Copilot, we’ve added prompt suggestions based on the document content. For example, if you open an academic paper on macroeconomic trends, you might see prompts like, “What is the current state of the labor market?” or ‘Main economic effects of the aging population in Europe” to start your journey with PDF Copilot. 

• Work with PDFs more easily using introductory messages and helpful prompts suggesting possible follow-up questions.
• Easily navigate to specific parts of the PDF doc where insights are being referenced.

Effortlessly manage and utilize your chat history

Want to provide a reading recommendation to your students but don’t have time to read the whole book? Open a document and ask PDF Copilot to summarize it. Export the summary as plain text via email and send it out to students—easy and efficient!

• We’ve made it easy to copy, export, or clear your chat responses. This flexibility ensures that you can retain important information and manage your data as you want.
• Exporting or copying messages in Chat will now produce a more readable and formatted output.

You can ask Copilot to summarize all the annotations for you - and get a comprehensive summary in seconds. 

PDF Copilot can summarize entire documents or selected sections with precision, and provide a shorter or longer summary when needed. It even provides clickable page references and highlights the exact paragraph on the referred page, so you can jump directly to the source.

• You will get a short summary of the document right after connecting to the PDF Copilot chat.
• To get a more detailed summary of a whole PDF, go to the chat panel and choose ‘Summarize’ action.
• If you need to summarize only a part of the text, select it and choose the ‘Summarize’ action.
• You can also get a short summary of all annotations in the document. 

Ask Anything 

You go through a patient’s medical record but can’t find information about the specific test? Just ask Copilot, “Does this document contain any mention of ultrasounds or MRIs?” - and get a detailed answer with references. 

You can ask any question you want, and PDF Copilot will respond with a clear, detailed answer. You can copy, regenerate, or share the response easily. Don’t know where to start? Use helpful prompts suggesting possible questions. To ask a question, go to the chat panel and type the question into the chat window. 

NEW! Translate

Need to quote a research paper in French? With the new ‘Translate’ quick action, you can translate text sections within a document from one language to another. There is no need to use an external translation tool! 

You can translate several paragraphs at once by invoking the context menu and choosing the ‘Translate’ action. You can translate from 80 languages into English, German, Spanish, French, Chinese, and Japanese (plus the language of your system if different from the 6 languages listed). 

NEW! Explain 

No more googling and researching vocabulary when you find an unfamiliar word in your document. Receive comprehensive explanations about specific terms, phrases, or text sections within the document using the new ‘Explain’ action.
