Best AI Scribe for Mental Health in 2026: A Head-to-Head Speed Comparison
The fastest AI scribe for mental health in 2026 is Mozu, generating notes in 21.2 seconds — over twice as fast as the next mental health-specific competitor. Here's how every major tool compares.
We took the same session recordings — a 15-minute intake and a 60-minute therapy session — and ran them through every major AI scribe we could get our hands on. We measured one thing: note generation time, defined as the time from clicking the stop button until the SOAP note is visible and ready for review.
Here's what we found.
What We Tested
Two standardized sessions, same audio, identical conditions across every tool:
- Session A: 15-minute session (brief intake/follow-up)
- Session B: 60-minute session (full therapy session)
The question is simple: how long do you wait before you can review your note?
If you're seeing 20+ patients a day, even 30 extra seconds per note adds up to 10+ minutes of dead time daily — just staring at a loading screen.
The Results
15-Minute Session
60-Minute Session
Note generation time = from stop-button click to note visible. Tested May 2026. Mentalyc, Commure, and heyberries excluded (unable to complete testing).
Here are the full results for reference:
- Heidi Health (General): 9.44s / 12.39s
- Twohold (General): 17.95s / 33.72s
- Mozu (Mental Health): 21.2s / 24.4s
- Doximity (General): 24.98s / 50.64s
- JotPsych (Mental Health): 51.97s / 76.57s
- Freed AI (General): 60.59s / 95.4s
- Upheal (Mental Health): 72.72s / 145.01s
Mentalyc, Commure, and heyberries could not be fully tested.
What This Means
Mozu is the fastest mental health scribe — and it's not close
At 21.2 seconds for a 15-minute session and 24.4 seconds for a 60-minute session, Mozu is the fastest AI scribe built specifically for mental health. It's also competitive with general-purpose tools on raw speed alone.
The other mental health-specific tools:
- JotPsych: 52 seconds and 77 seconds. More than double Mozu's time on both sessions.
- Upheal: 73 seconds and 145 seconds. That's nearly two and a half minutes of waiting after a one-hour session.
- Mentalyc: We were unable to complete the note generation workflow during testing.
General-purpose scribes are fast — but speed isn't the whole story
Heidi Health posted the fastest raw times at 9.4 and 12.4 seconds. Impressive — but Heidi is a general-purpose medical scribe built for enterprise workflows, not individual mental health clinicians.
When you're documenting a therapy session, the details matter: which therapeutic interventions were used, risk assessment language, treatment plan alignment with DSM-5-TR criteria, and the specific documentation that payers expect for behavioral health claims.
A fast first draft that needs significant editing to meet behavioral health documentation standards isn't actually saving you time. The real metric is time-to-signed-note, not time-to-first-draft.
What about Doximity and Twohold?
Doximity (25.0s / 50.6s) and Twohold (18.0s / 33.7s) are both general-purpose tools that posted competitive 15-minute times. But on 60-minute sessions — the bread and butter of therapy — their times roughly double, while Mozu stays flat at 24.4 seconds. Like Heidi, neither is built for mental health documentation specifically.
Mozu is fast and built for your specialty
Mozu sits in a unique position: near the top on raw speed, and purpose-built for mental health documentation. You're not choosing between fast and accurate — you're getting both.
Beyond Speed
Speed gets you out of the loading screen faster. These features keep you out of trouble:
Audit protection
Payers are scrutinizing behavioral health claims more aggressively — especially 90837 (60-minute therapy) and add-on codes like 90785 (interactive complexity). Mozu flags documentation gaps before you sign, so you're not discovering problems after a claim is denied.
Billing code suggestions
Mozu suggests CPT and ICD-10 codes based on what actually happened in the session. Less time looking up codes, fewer claim denials.
Built for how therapy actually works
General-purpose scribes are trained on 10-minute primary care visits. They struggle with 60-minute therapy sessions — missing therapeutic modality documentation, flattening risk assessment language, or failing to capture the medical reasoning that justifies your billing codes. Mozu understands the difference between a CBT intervention and motivational interviewing, because that's all it does.
Tools We Couldn't Test
- Mentalyc: Mental health-specific, but we couldn't complete the note generation workflow.
- Commure: Requires contacting sales. No self-serve access.
- heyberries: Couldn't get past the demo page.
Bottom Line
If you're choosing an AI scribe for mental health:
Mozu is the fastest mental health-specific scribe at 21–24 seconds, with built-in audit protection and billing code suggestions. It's also competitive with general-purpose tools on raw speed.
Heidi Health is faster on raw generation time, but it's a general-purpose enterprise tool — not built for behavioral health documentation.
Freed AI, Upheal, and JotPsych are significantly slower. Switching to Mozu saves you 30–120 seconds per session. Across a full caseload, that's hours per week.

3. How does Mozu compare to Freed AI?
Freed AI takes 60.59 seconds for a 15-minute session and 95.4 seconds for a 60-minute session. Mozu is roughly 3x faster at 21.2 seconds and 24.4 seconds. Freed is also a general-purpose scribe, not specialized for mental health documentation.
4. Is Mozu free to use?
Yes. You can sign up for Mozu for free with no credit card required and unlimited sessions.
5. How is note generation time measured?
Note generation time is measured from the moment the user clicks the stop button until the SOAP note becomes visible and ready for review in the note section.
6. Does Mozu work with my existing EMR?
Yes. Mozu works alongside your current EMR — no data migration required. It generates the note draft, which you can then review, edit, and transfer to your system.
Benchmarks conducted May 2026. Note generation time = stop-button click to note visible. Results may vary by audio quality, session content, and network conditions. All tools tested on their latest available versions.
