Offline work is currently only supported on the Rayyan mobile app and not the Web application.
You can now use Rayyan Mobile App to download your reviews and make include and exclude decisions offline. Once you're online the decisions will reflect on your review in realtime.
The app is super simple to use and with the option of working offline, you can use it while commuting, waiting for meetings or classes to start, or relaxing with a cup of coffee. Rayyan ensures that your flow and productivity both remain uninterrupted.
