The ranking
How we decided #1. We rank on the 3 checks that decide whether a tool does this job: Active Recall Support, Study Material Handling, Summary Output Quality. A check only carries a score when we recorded a finding for it, and a tool has to be measured on all of them to take the top spot. We also checked Overall Revision Workflow Support, Traceability & Transparency — compared for you, but not part of the ranking.
