What is Rayyan?

Rayyan is a platform built for researchers who conduct systematic reviews and evidence synthesis. It brings the entire review workflow into one place, from screening references to extracting data. Over a million researchers use it across more than 190 countries, and it is designed to handle projects ranging from small studies to reviews with millions of references.

You start by importing your references. Rayyan helps you remove duplicates automatically using your own protocol, then guides you through screening with AI-assisted prioritization. You can work on the web or through the mobile app, even offline. Hot keys let you move quickly through decisions. The ResearchPilot feature adds zero-shot relevance ratings, an AI analyzer, an AI reviewer, and auto data extraction to speed things up further.

Rayyan suits research teams that need transparency and auditability. Every decision is traceable, and the platform generates PRISMA diagrams and audit trails. It also supports team coordination through data sampling and workload division. The site notes it is free forever for basic use, with no credit card required to start.
