Heidi is one of the biggest ambient AI scribes in medicine, reporting millions of consults per week across 110+ languages, and it is widely used by therapists and counselors alongside physicians. The free plan includes unlimited AI notes, which makes it the most common starting point for clinicians experimenting with AI documentation. Paid tiers add EHR integrations (including Epic and athenahealth), team features, and priority support. Templates are customizable, so therapists can shape SOAP or DAP outputs to their style, though its templates are less mental-health-specialized out of the box than tools like Mentalyc or Twofold. A BAA is available for US clinicians. Reviews in 2026 are mixed on support responsiveness as the company has scaled, so trial it against a specialist scribe before committing a group practice.
