"With Delta, I'm fully present with the person in front of me: I no longer rebuild the protocol from memory. I pick up right where we left off, session after session, and adjust. "

Two ways to work

A complete clinical note,
without writing it.

1 Live During the session
Were you able to practise the exposure between sessions?
Yes, I managed to speak up in a meeting.
It was stressful, but I did it.

Session report ready, in your style ready to file
After the session

Everything you write, drafted for you.

From the session (captured live or dictated afterwards), Delta produces the complete document, in your template and your theoretical framework. You review, adjust, and export.

Session report generated by Delta
Session report
A structured summary after every consultation, linked to previous sessions.
Follow-up report
A status update on the protocol: what's been worked on, what's changing.
Summary for the patient
A clear status update to hand to the patient, in accessible language.
In your template. Delta learns your way of writing: the more you use it, the more the result sounds like you.
The real change

It's not just faster.
It's a different kind of follow-up.

Before Delta
The thread of each case pieced together from memory, every session.

Note-taking that pulls you away from the person in front of you.

With Delta
Before the session: the protocol, the last session, what was agreed as homework.
The exercises you set, brought back: they show up in the pre-session brief.
Fully present in session: the note is written while you work.
What is moving and what is stuck, visible from one session to the next.
In the evening, nothing left to catch up on.
Security & patient confidentiality

Your sessions will never train an AI.

Zero training. Your patient data serves only you, never to improve a model. It's our most important commitment, because that data belongs to you and your patients, not to us.

Your data is encrypted
AES-256 at rest, and encrypted in transit. Unreadable without the key.
HDS hosting in France
Your health data stays in France, with a certified host.
HDS-certified
Audio deleted after transcription
No audio is retained. The file is destroyed as soon as transcription is complete.
Automatic pseudonymisation
Identifiers are stripped from the record before anything reaches an AI model: it only ever sees the clinical content.
GDPR-compliant, DPA in place
Your patient data stays yours: you decide what's kept or deleted. Delta processes it solely on your behalf, governed by a GDPR-compliant data processing agreement (DPA).
You stay in control
Export and delete your files at any time. Your data belongs to you.

Region and language

Is Delta compatible with my therapeutic approach?

Yes. Delta offers templates for the main approaches: CBT, EMDR, ACT, hypnotherapy, sophrology, systemic approaches, humanistic, schema therapy, brief therapies. You can also create and customise your own templates so they match your practice. The AI adapts to your clinical vocabulary.

Does Delta replace my current note-taking tool?

Yes. Delta replaces your note-taking tool and your patient record: the note writes itself and you read it over. You can also keep the record you use today and copy what Delta produces into it. Delta links each consultation to the previous ones and generates all your clinical documents: session notes, follow-up reports, letters to the patient's GP, referral letters, summaries for patients.

In practice, you no longer juggle a note-taking tool, a patient file, and a letter generator: Delta does all three, plus longitudinal clinical memory. Most of our users arrive with a notebook, a Word file, or notes typed between two patients.

Does Delta replace my practice-management software (scheduling, billing)?

No, and that's by design. Delta focuses on the clinical and documentation side: session notes, reports, letters, patient memory. Your scheduling, appointment booking, and billing stay on the tool you already use (Doctolib, your practice-management software…).

Delta works alongside it, it doesn't replace it: you retrieve every document in one click (copy-paste, PDF, structured export) to file wherever you want. No migration required, no duplicate data entry.

Does Delta make diagnoses or decisions on my behalf?

No. Delta is a documentation and drafting tool: it formats what you observe and decide, in your style. It makes no diagnosis, recommends no course of care, and never substitutes for your clinical judgment.

The evidence from the literature that Delta can display is general and purely informational: food for thought at your discretion, never a recommendation for a given patient. The clinical decision is always yours.

Do I need to inform my patients? And how?

Yes, informing the patient is required under GDPR. Article 9.2.h of the GDPR provides for the processing of health data by a professional bound by confidentiality, as part of your patients' care. On that basis, written consent is generally not required. You remain the data controller, so it is for you to judge what your own practice calls for.

In practice, Delta provides you with an information poster to display in your practice or waiting room, stating that you use Delta so you can focus fully on your patients. This is the approach taken by the leading tools on the market.

If you'd like to go further, you can mention Delta verbally at the start of the first session: some practitioners prefer this direct transparency. The patient can always decline: in that case, you take your notes manually as before. Delta stays entirely optional, session by session.

Do my notes stay confidential from my patients?

Absolutely. Your session notes are strictly private, intended solely for your clinical use. Patients have no direct access to them. If a patient asks to view their file (GDPR right of access), it's up to you to decide what you share: Delta never does this automatically. Professional confidentiality is fully respected.

Can I use Delta for teleconsultations?

Yes. Delta works just as well in person as in teleconsultation. Audio can be captured via your computer's microphone, your video tool (Doctolib, Livi, Qare, etc.), or your phone. It's automatically deleted as soon as transcription is complete.

Does Delta comply with the ethical framework of my practice?

Yes. Delta is designed to fit within the ethical framework of your practice. The patient is informed that the session is being captured (Delta provides an information poster and a sample verbal disclosure) and can decline at any time. In that case, you take your notes manually, session by session. Professional confidentiality is preserved, the data is hosted in France with an HDS-certified host, and you keep full control over what is kept or deleted.

How does Delta handle clinical supervision?

Delta helps you prepare for supervision sessions: you can generate an anonymised summary of a clinical case in one click, with the structured history, changes over time, and your own questions. You no longer start from scratch the night before every supervision.

Can I import my old patient files?

Yes. Delta lets you import your old files (Word notes, PDFs, or manual entries) so your clinical memory starts with the existing history. We support you free of charge with this step when you move to the Pro plan.

What happens if I stop using Delta? Can I get my files back?

Your files belong to you. At any time, you can export all your notes, reports, and case histories as a PDF or structured format (JSON). After cancellation, you have 90 days to retrieve your data before permanent deletion.

No technical lock-in: your documents remain 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 developmental milestones), couples therapy (accounting for both voices), family and systemic therapy, and group therapy. The AI identifies the different speakers in the consultation.
