Heidi Health vs LucasAI (2026)
Heidi and LucasAI both sell ambient scribes that clinicians can start on their own and that reach beyond the note, and LucasAI's comparison page names Heidi as an alternative. Heidi is global; LucasAI is built around US billing. Heidi reports more than 175 million patient interactions across more than 190 countries, with a free tier and a $110 Clinician plan billed annually. Heidi Evidence answers clinical questions with BMJ content, Heidi Comms handles patient calls, and Heidi II agents prepare charts and sweep panels. Its certifications include SOC 2 Type II, ISO 27001 and ISO 42001, and it says customer data never trains models. LucasAI focuses on US practices, with coding confirmed by the clinician or coder, HCC and V28 analytics, prior authorization support and Medicare ready wound care DME ordering. Heidi suits a clinician or organization that wants a broadly certified scribe with jurisdiction specific compliance; LucasAI suits a US practice that wants documentation tied to coding and authorization work.
