Rayyan vs Sysrev
Rayyan scores 8.2 to Sysrev's 5.1 among the systematic review platforms we rate, and is the better pick for 3 of the 5 kinds of buyer below.
Rayyan wins, 8.2 to 5.1
Sysrev searches PubMed and OpenAlex directly inside the app, where Rayyan only imports references you already found elsewhere. Rayyan counters with automatic reference deduplication, a PRISMA flow diagram, and an announced risk of bias assessment, none of which Sysrev offers, plus a mobile app that Sysrev lacks. Rayyan's cheapest paid plan is $8.33 a month, billed quarterly; Sysrev costs $50 a month per member.
Pick Rayyan if you need deduplication, PRISMA, risk of bias and a mobile app.
Pick Sysrev if you want to search PubMed and OpenAlex without importing first.
