What does Open Paper do?

Open Paper is an AI-powered research assistant that helps you read, understand, and analyze academic papers. You upload research papers in PDF format, and the tool processes them to provide AI-generated summaries, annotations, and answers to your questions. It maintains a personal library of your uploaded papers and keeps all your annotations synchronized across devices.

The tool stands out because every AI response includes clickable citations that link directly to specific sections of your paper. This means you can verify where the information comes from and maintain academic integrity. The interface shows your paper and the AI chat side-by-side, so you never lose context while reading. You can also group related papers into projects and ask questions that span multiple documents.

Open Paper is particularly useful for PhD students, academics, and industry researchers who need to process large volumes of literature quickly. It helps with literature reviews by extracting structured data from papers and exporting it to CSV format. The entire platform is open-source, allowing researchers to inspect the code and contribute improvements.
