Clinical evidence search, built and hosted in the European Union
CliniAtlas is an EU-hosted clinical evidence search platform for verified healthcare professionals. It answers general clinical and scientific questions with agentic search across peer-reviewed literature and European regulatory and guideline sources, and places citations beside the claims they support. When OpenEvidence withdrew access from the European Union and United Kingdom in April 2026, it cited regulatory uncertainty, including the EU AI Act. CliniAtlas was built for European practice from the start: processed in the EU, grounded in European sources, and available in your language.
