Reading Assistant

Beaver is integrated inside your PDF reader, providing instant explanations and insights without ever leaving the page you're reading.

Get Explanations as You Read

Select complex equations or highlight text to get explanations. Beaver can see what you're looking at and has access to the entire document, making it easy to ask questions at any level:

What does this equation mean?
Can you explain the methods?
What are the main findings?

Connect to Your Library

Need more context? Ask how a claim compares to the rest of your library without leaving the page:

How do other papers in my library measure this concept?
How do others define this term?
What papers in my library contradict this finding?

Adding Annotations to the Conversation

Add PDF annotations to ask questions about specific parts of the document:

  • Area selection: Select a region (figure, table, equation) and add it to ask questions about it
  • Text selection: Highlight text and add it to discuss that specific passage
  • Note annotation: Share a note annotation to add it to the conversation

Creating new PDF annotations with Beaver

Ask Beaver to create new annotations in PDF files:

Add annotations to highlight key findings in this PDF.
Add note annotations that compare this article's key findings to related studies in my library.
Identify all definitions of key concepts. Add note annotations to compare them with alternative definitions in my library.
Explain all technical terms in simple language using note annotations.

Limitations

Currently Beaver cannot access existing annotations in a document unless you manually add them to the conversation.
