Since the last session

Anticipatory anxiety before the 04/12 presentation. 4-7-8 breathing consolidated. Sleep stabilized since S6.

Longitudinal memory

In S3, your client mentioned apprehension about Thursday meetings.

  • Client context in 10 seconds

    Clear summary, points to revisit, objectives — to start the session immediately.

  • Longitudinal memory

    Delta connects the threads between sessions. What was raised in S3 resurfaces at the right moment.

  • An active caseload mastered

    Whether you support 15 or 50 clients, every record finds its own context, instantly.

02 During the session

Focus on your client. Delta documents.

  • Automatic notes + your annotations

    Delta writes the documentation. You add your clinical impressions — what AI can't capture for you.

  • Visible therapeutic threads

    Recurrences and older themes are visualized in the client record — you decide when to come back to them.

  • Discreet transcription

    The session unfolds normally. Your attention stays on your client, not on your computer.

Frequently asked questions from therapists.

Everything you need to know before getting started.

Is Delta compatible with my therapeutic approach?
Yes. Delta offers templates for the main approaches: CBT, EMDR, Ericksonian hypnosis, ACT, sophrology, systemic, schema therapy, brief therapies. You can also create and personalize your own templates so they fit your practice. The AI adapts to your therapeutic vocabulary.
Do I need to inform my clients? And how?
Yes, informing the client is required by GDPR. Depending on your status, the modalities vary: if you are an ARS-registered psychotherapist, healthcare professional or subject to professional secrecy, Article 9.2.h of the GDPR applies and you don't need formal written consent. For other statuses (CBT practitioner, hypnotherapist, sophrologist, therapeutic coach), explicit consent from the client is required.

In practice, Delta provides you with an informative poster to put in your practice or waiting room, indicating that you use Delta to fully focus on your clients. This is the approach used by the leading tools in the market.

If you want to go further, you can mention Delta verbally at the start of the first session — some clinicians prefer this direct transparency. The client can always refuse: in that case, you take notes manually as before. Delta remains entirely optional, session by session.
Are my notes confidential vis-à-vis my clients?
Absolutely. Your session notes are strictly private, intended only for your therapeutic use. Your clients have no direct access. If a client requests to view their record (GDPR access right), it is up to you to decide what you share — Delta never does so automatically. Your confidentiality frame is fully respected.
Can I use Delta in teleconsultation?
Yes. Delta works just as well in-person as in teleconsultation, via your computer microphone, your video tool (Doctolib, Livi, Qare, etc.), or your phone. Audio is automatically deleted within 24h after transcription.
Does Delta respect my deontological frame?
Yes. Delta respects the requirements common to the various deontological frames (ARS psychotherapists, professional federations for CBT, EMDR Europe, CFHTB for hypnosis, etc.). Client consent for using Delta is systematically obtained (Delta provides an informative poster and a model verbal mention), confidentiality is preserved, data is hosted in France with a certified HDS provider, and you keep full control over what is kept or deleted.
How does Delta handle clinical supervision?
Delta helps you prepare your supervisions: you can generate an anonymized synthesis of a clinical case in one click, with the structured history, evolutions and your questions. No more starting from scratch the day before each supervision.
Can I import my old client records?
Yes. Delta allows you to import your old records (Word notes, PDF, or manual entries) so that clinical memory starts with the existing history. We support you for free on this step when you upgrade to the Pro plan.
What happens if I stop Delta? Can I recover my records?
Your records belong to you. At any time, you can export all your notes, summaries and client histories as PDF or structured format (JSON). After cancellation, you have 90 days to recover your data before permanent deletion.

No technical lock-in: your documents stay readable outside Delta, and your clinical memory can be re-imported elsewhere if needed.
Does Delta work for specific populations (children, couples, groups)?
Yes. Delta offers dedicated templates for child and adolescent therapy (with a development grid), couples therapy (taking both voices into account), family and systemic therapies, and group therapy. The AI identifies the different speakers in the consultation.
