Mentalyc vs Nudge AI (2026)
Two behavioral health documentation products, one written for therapists and one for the whole prescribing and therapy roster. Mentalyc publishes the paperwork a solo buyer has to rely on: a business associate agreement in full, signed with every account, tiers priced by note volume from about $20 a month, and an extension that names the seven record systems it writes into. Its input options are the widest here, since a note can come from a live recording, a session alongside any video platform, an upload, a dictation or typed text. Nudge covers more clinician types and reaches into level of care documentation, which is where behavioral authorization is actually decided. Its published prices and its data handling are both specific, down to a seven day audio deletion and a plain statement that customer data is not used for training. Where the two diverge is integration and assurance. Mentalyc names the systems it writes into. Nudge claims twenty five or more supported systems and names none of them, which is the first thing to ask about. The other question to ask Nudge is about its own language on billing opportunities: in this specialty documentation decides what care gets authorized, and a tool tuned to find more of it is not the same as one tuned to describe the patient.
- The paperwork is published rather than promised: a business associate agreement in full, signed with every account, and tiers priced by note volume from about $20 a month.
- Notes can come from a recording, an upload, a dictation or typed text, which fits clinicians whose clients will not consent to recording.
- The extension names the record systems it writes into, so a practice can see its own system on the list before buying.
- Coverage spans the clinician types who actually practice behavioral health, psychiatrists, psychologists, therapists, counselors and psychiatric nurse practitioners, reaching into level of care documentation.
- Its data answers are specific enough to hold it to: audio deleted within seven days, no training on customer data, and named controls behind the claim.
- A free tier with five notes and no credit card lets a clinician test the output before any commitment, alongside three published tiers with figures.

How do Mentalyc and Nudge AI handle patient data?
Transcripts are anonymized before processing, with a partial option that keeps first names for family sessions, and Mentalyc treats anonymized transcripts as outside the medical record. Session data is never used to train AI models, the clinician can delete any session data at any time, and account data is kept while the account is active.

Neither vendor publishes an accuracy figure, model card or evaluation method, and neither publishes results across accent or dialect, which matters in this population because medication effects on speech compound that variation. Nudge describes identifying billing opportunities in its own language, which places it on the coding gradient, so ask what proportion of its suggestions survive payer review. Two Nudge gaps are worth pressing.
It publishes no attestation of any kind and the button offering one leads nowhere, so there is no independent check of its security to read. And its business associate position is contradicted across its own pages: earlier material scoped agreement support to enterprise use while the pricing page marks the free tier fully compliant, which leaves a solo clinician on a cheap tier recording psychotherapy without knowing whether an agreement covers them.
Mentalyc states a SOC 2 Type II attestation as its own without a report period, auditor or scope, and its security page gives two answers about session audio, up to three days in one place and immediate deletion in another. Mentalyc also markets risk detection and safety planning in every note so that nothing critical is missed, an absolute promise about omissions that signing a note cannot check.
