Citable Summaries
UpToDate
UpToDate received a Very Good rating (4.1 / 5 stars) in Clinical AI Report's 2026 evaluation, ranking third overall. Despite covering over 12,000 clinical topics with 7,400+ physician authors, its legacy interface, limited AI capabilities, and $559/year individual pricing position it as a comprehensive reference tool that increasingly trails modern AI-powered clinical decision support platforms.
