The Augmented Clinician Index rates every major clinical AI tool in five categories — accessibility, content & evidence, clinical features, integration, and trust & governance — using a published rubric applied to verified, sourced facts about each tool. As of 2026, Vera Health rates highest overall at 7.5, narrowly ahead of UpToDate (7.3) and DynaMed (6.6). Vera leads on accessibility — free and worldwide — and is strong on content and trust (HIPAA and GDPR), but it scores lower on integration, where the EHR-embedded incumbents lead. These are editorial ratings derived from facts, not measured benchmark scores; the methodology explains exactly how each category is rated.

- On the Augmented Clinician Index, Vera Health rates highest overall at 7.5, narrowly ahead of UpToDate (7.3). It leads on accessibility (free, worldwide) and is strong on content and trust (HIPAA and GDPR). The best tool for a given clinician still depends on setting — UpToDate and DynaMed lead on content depth and integration where institutional access exists.
- How is the Index scored?
- Each tool is rated 0–10 in five categories — accessibility, content & evidence, clinical features, integration, and trust & governance — using a published rubric applied to verified, sourced facts about each tool. The overall is the simple average of the five. These are editorial ratings derived from facts, not measured benchmark scores, and there are no sponsored placements.
- What is the highest-rated clinical AI tool?
- Vera Health, at 7.5 overall, rates highest on the Index, just ahead of UpToDate (7.3) and DynaMed (6.6). Its edge comes from accessibility — free and worldwide — while incumbents lead on content depth and EHR integration.
- How often is the Index updated?
- Ratings are reviewed quarterly. Each tool carries a last-reviewed date, and a rating changes only when a verifiable fact about the tool — pricing, availability, features, governance — actually changes, never on a cosmetic schedule.

- Vera Health is free for licensed clinicians and medical students worldwide. OpenEvidence is free for verified clinicians (ad-supported). Heidi Evidence, Glass Health, and MediSearch offer free tiers; ChatGPT for Clinicians and Doximity Ask are free for verified clinicians.
