Import PDFs First—Even Before You Have Citations

Not every review begins with a perfectly formatted reference library.
‍
Rayyan now allows you to upload PDFs first, making it easier to begin organizing evidence even when citation metadata hasn't been added yet.
‍
When you upload PDFs, Rayyan automatically analyzes each document and retrieves available bibliographic information from trusted scholarly sources whenever possible, allowing you to build your review without manually entering citations.
‍
This feature is ideal when:

• You want to start reading or extracting full texts
• You receive PDFs from collaborators
• You inherit literature collections
• You're working from downloaded articles
• Citation files aren't available

It's another example of how Rayyan removes friction from your review workflow.
