Imagine you're working with a 300-page engineering textbook and need to find information on a specific topic.

The PDF will provide you with accurate answers and show you the sources in the viewer, allowing you to navigate the information effortlessly.

As an example, we've included the link to the Bitcoin whitepaper below. You can try the Chat with Your PDF feature and ask questions about the principles, technology, or applications of Bitcoin, such as "What is the proof-of-work system?" or "How does the blockchain prevent double-spending?".

Technical Details

Now, let's dive into the technical side of Chat with Your PDF. The secret sauce behind this innovative feature is vector search, or similarity search, which differs from more common search methods like fuzzy search. But what is vector search, and how does it work?

Vector search, also known as similarity search or nearest neighbor search, is all about finding similar items within a dataset. Instead of focusing on keywords or exact matches, vector search uses embeddings to transform text into a multidimensional vector space. These embeddings capture the semantic meaning of the text, enabling comparisons between sections of a document based on their content and context.

The Future: Vector Search for Enterprise

Our vision for the future of document interaction goes beyond individual PDFs. We're currently working on offering companies the ability to search through large volumes of documents using vector search. This powerful feature will quickly display the most relevant sections in documents based on user questions, significantly enhancing efficiency and productivity.

If your company is interested in harnessing the power of vector search for large-scale document management, don't hesitate to contact us for early access to this cutting-edge technology.


Chat with Your PDF is a groundbreaking feature that leverages the power of vector search to redefine how you interact with documents. By turning your PDFs into conversational partners, you'll save time and improve your understanding of complex information. Don't miss out on the future of document interaction – try Chat with Your PDF today and stay tuned for our upcoming enterprise solutions!
