Heidi vs Mentalyc: Detailed 2025 Comparison

Clinicians choosing an AI documentation partner in 2025 often narrow the field to Heidi Health—the cross‑specialty “ambient scribe” with global ambitions—and Mentalyc—the therapist‑first platform that layers analytics and treatment‑plan tools onto automated notes. Below you’ll find a fully updated, research‑driven analysis to help you decide which (if either) is the best fit.

Heidi Overview

Strengths

• Unlimited notes even on the Free tier, good for try‑before‑buy.
• Best‑in‑class security stack and multiple global certifications.
• “Ask Heidi” lets clinicians instantly regenerate letters, summaries or coding from the same transcript.
• Large enterprise references (NHS, Beth Israel, ForHealth).

Watch‑outs

• Flat $99 Pro price is higher than Mentalyc’s entry plans.
• Direct EHR push beyond copy/paste may require custom work on Enterprise.
• Ambient model works best with live recording; upload‑only workflows are less emphasized.

Mentalyc Overview

Strengths

• Deep library of therapy‑specific templates and CPT coding out of the box.
• Alliance Ginie™ gives objective alliance metrics—unique in the category.
• Lower entry prices; Mini tier suits very small caseloads.
• Transparent note caps prevent runaway costs for low‑volume users.

Watch‑outs

• Hard monthly caps (40–330 notes); overages force plan jumps.
• No ambient “always‑listening” mode—requires recording upload or telehealth integration.
• Lacks native mobile apps; browser‑based on phones can feel cramped.

Heidi vs Mentalyc — Head‑to‑Head

Pricing Reality Check

• A solo therapist seeing <2 clients / day will pay $19.99 on Mentalyc Mini versus $0 on Heidi Free—but Heidi will consume 10 “Pro actions” quickly if you need letters or custom formats.
• At >8 clients / day, Mentalyc Pro (160 notes) often trips caps, pushing users to $119.99 Super; Heidi’s $99 Pro remains flat with no limit.
• Enterprise deals for both vendors are custom; Heidi touts multi‑team SSO and MFA; Mentalyc offers per‑seat team plans with unlimited notes (fair‑use).

Security & Compliance Snapshot

Heidi’s additional ISO 27001 and global privacy badges may simplify procurement for hospitals, while Mentalyc’s radical‑transparency landing page and in‑app consent templates resonate with solo practices.

Which One Fits Your Scenario?

Why Twofold May Be the Better Choice

Twofold Health combines Heidi’s unlimited usage and enterprise‑grade compliance with Mentalyc’s mental‑health focus:

• Therapist‑first design plus customizable templates for 25 + specialties.
• HIPAA BAAs, US‑only hosting, optional data‑retention controls.
• Unlimited notes at $49/mo (annual)—half Heidi Pro and no Mentalyc‑style caps.
• Mobile apps, Zoom plug‑in, and one‑click EHR push included, no add‑ons.

For teams that outgrow Mentalyc’s quotas or find Heidi’s generic templates lacking nuance, Twofold delivers a balanced alternative.

Conclusion

Heidi excels in scale, security and unrestricted usage, making it a top choice for high‑volume or multi‑disciplinary settings. Mentalyc, meanwhile, offers therapy‑specific intelligence, granular note formats and lower entry pricing that resonate with solo and small‑group practices. Evaluate your session volume, specialty needs and integration preferences—then weigh whether a hybrid option like Twofold can give you the best of both worlds at a sharper price point.
