Heidi vs Mentalyc: Detailed 2026 Comparison

Clinicians choosing an AI documentation partner in 2026 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

Last verified January 2026

Heidi Pros

• 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).

Heidi Cons & Limitations

• Flat $99 Pro price is higher than Mentalyc’s entry plans.
• Direct EHR push beyond copy/paste may require custom work on the Enterprise.

• Transparent note caps prevent runaway costs for low‑volume users.

Mentalyc Cons & Limitations

• 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 Comparison: Key Features, Pricing & Compliance

• 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.

Heidi vs Mentalyc: Which One Fits Your Needs Best?

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.
