Psynth vs. Mentalyc: Therapy Notes Tool or Report-Writing Tool?

Choose Mentalyc if you're a therapist who needs AI progress notes, treatment plans, and session insights for a weekly caseload. Choose Psynth if you're a psychologist whose main work is assessment, and what you need drafted is the full psychological evaluation report, not the session note.
‍

The two get compared because both use AI to take documentation off a clinician's plate, and both list psychologists among their users. But they're built around different documents. Mentalyc is a notes tool: it turns a session into a SOAP, DAP, or BIRP note and tracks progress across sessions. Psynth is a report tool: it turns a battery of test scores and records into a draft evaluation report. If you're searching for a Mentalyc alternative, the first question is which of those two documents you actually need help with.
‍

What is Mentalyc?

Mentalyc is an AI note-taking and clinical documentation tool for therapists, counselors, and other mental health professionals. It records or receives session content, then drafts progress notes, treatment plans, and progress summaries, and it offers session analytics, including a therapeutic alliance score it calls Alliance Genie.
‍

Here is what Mentalyc publishes, as of October 2026 (Mentalyc):
‍

• Note formats: SOAP, DAP, BIRP, GIRP, PIE, intake notes, MSE, biopsychosocial assessments, supervision notes, and treatment plans.
• Capture: record in-person or telehealth sessions, upload audio, dictate a recap, or type a summary.
• Clinical tools: an AI treatment planner, a progress tracker, and Alliance Genie, which Mentalyc describes as alliance scores "derived from session content, not from a client questionnaire."
• EHR: Mentalyc says it works with EHRs such as SimplePractice, TherapyNotes, and Jane App.
• Security: Mentalyc states it is HIPAA, PHIPA, and SOC 2 compliant, offers a BAA, and deletes session audio "once your note is ready."
• For psychologists: Mentalyc says "Psychologists use Mentalyc for testing summaries, progress tracking, and cross-session analytics."
  ‍

That last line matters for this comparison. Mentalyc does support psychologists, and a testing summary is a useful document. It's a different job from drafting a complete evaluation report built on a multi-measure battery.
‍

What is Psynth?

Psynth is purpose-built for the psychological assessment report. You bring the evaluation data (test scores, PDFs, records, handwritten notes), and Psynth produces a PhD-smart first draft for you to review, edit, and sign. The psychologist interprets and diagnoses; Psynth organizes the data and drafts the language.
‍

What that looks like in practice:
‍

• 450+ supported assessments, so measures like the WISC-V, BASC-3, and Vineland are recognized by name.
• Test-by-test format, which keeps PHI from one report out of another.
• No AI data retention: Psynth's AI vendors retain no data, and patient data is never used to train models.
• Compliance: HIPAA, PIPEDA, GDPR, SOC 2 Type 2, and ISO 27001, third-party verified by Assured Information Solutions (AIS).
• Ambient listening for assessment sessions, so intake interviews and feedback sessions can be captured alongside the report. We wrote about how that capture should behave in our post on ambient listening for psychologists.

Where Mentalyc is the better fit

For many clinicians, Mentalyc is the right call. Here's where it has the edge.

You see clients every week. A therapist with a full caseload writes dozens of progress notes a week. Mentalyc is built to make that note fast, in the format your payer or supervisor expects, and to support group, couples, family, and child modalities on its higher plans (Mentalyc Pricing).

You want insight across sessions. Progress tracking and alliance scores are designed for ongoing treatment, where the question is how a client is changing over months. Psynth isn't built for that.

You want to keep your EHR and add notes. Mentalyc says it works with SimplePractice, TherapyNotes, and Jane App, so it can slot into a therapy workflow you already have.

You want a low monthly entry point. Mentalyc's solo plans are priced by monthly note volume, which is easy to size to a caseload.

Where Psynth is the better fit

The balance shifts when evaluations, not sessions, are the core of the practice.

‍

The report is your product. A psychological evaluation integrates a battery of measures, records, observations, and history into one narrative with a diagnosis and recommendations. That's a longer, higher-stakes document than a session note, and it's the one Psynth drafts. Dr. Lexie Molina, who runs a solo psychoeducational practice, went from 3 to 4 hours per report to about 15 minutes for a first draft. She hasn't worked a weekend since.

You're integrating many data points. Dr. Edgington, who handles complex evaluations, described Psynth as an intelligent workspace that organizes the "puzzle pieces," which reduced the mental load of switching between systems.

You need capacity without hiring. Dr. Taylor Fladhammer's high-volume practice saw a 2 to 3x increase in assessment capacity and a 4x improvement in report speed. For families on a waitlist, that turnaround is the difference.

You want the report and the session capture in one place. With ambient listening in the same workspace as the report, the intake interview and the test data end up in one place instead of two tools.
‍

What about psychologists who do both?

Plenty of psychologists carry a therapy caseload and run evaluations. For them, this isn't either/or. A notes tool handles the weekly sessions; a report tool handles the evaluations. The mistake is expecting one to do the other's job well. A tool designed for session notes won't be organized around a WISC-V, a BASC-3, and a stack of school records, and a report tool isn't designed to track therapeutic alliance across 30 sessions.

If you're also sorting out how you document therapy sessions, our guide to psychologist notes covers formats and what to include.
