Compare clinical AI tools for European practice

Each page below puts CliniAtlas next to one or two tools European clinicians ask about, on the questions that decide whether a tool is usable from the EU or UK: who can sign up, where queries are processed, which sources are searched, whether every claim carries a citation you can open, and what it costs. CliniAtlas is our product. We are not affiliated with any of the others, and we say so on every page.

How these comparisons are made

Competitor rows describe public product materials, privacy policies, and published statements as of the date printed on each page, with the sources listed at the foot. We do not quote prices that can change, we do not report head-to-head accuracy results we have not run, and we do not decide any product’s regulatory classification. When a product changes its offer or a reader points out an error, the page is updated and the date moves. Corrections are welcome at hello@discensmachina.com.

For CliniAtlas itself, the published evaluation methodology and the HealthBench Hard results describe what has been measured and how.
