What is Heidi Evidence?
Heidi Health is best known as an ambient AI medical scribe that transcribes encounters and auto-generates structured notes. In February 2026 it launched Heidi Evidence, a cited clinical-evidence search tool that expands the product beyond documentation, returning answers grounded in recognized sources such as NICE, BMJ, Cochrane, and MIMS. Heidi Evidence is free for individual clinicians, with a paid “Evidence Plus” tier, and Heidi’s architecture is model-agnostic rather than tied to a single LLM. The company raised a $65M Series B in October 2025, led by Point72.
What is Heidi Evidence best at?
- Free, and attached to a widely used scribe. Heidi Evidence is free for individuals and rides on a documentation product many clinicians already use, which lowers the barrier to trying it.
- Recognized sources. Answers are grounded in named, reputable sources such as NICE, BMJ, Cochrane, and MIMS.
- Broad reach. The underlying platform supports a wide range of languages and specialties across many countries.
What are Heidi Evidence’s limitations?
- New to evidence search. It launched in February 2026, so its depth and benchmark track record are still being established relative to dedicated evidence engines.
- Accuracy on complex cases. Third-party reviews note accuracy can degrade on complex, multi-problem encounters, and general LLM-scribe tools carry a known hallucination and fabrication risk, so output needs verification.
- Evidence search is an add-on, not the core. Heidi’s core product is documentation; evidence search is a recent expansion, whereas dedicated engines are built around it.
Who is Heidi Evidence best for?
Clinicians already using Heidi as their ambient scribe who want cited evidence answers in the same tool without paying extra, particularly in UK and Commonwealth settings where its NICE and BMJ grounding fits well. Clinicians who want a purpose-built, evidence-graded search engine as their primary reference, rather than a scribe add-on, should compare it with Vera Health.
