About

Designed with psychologists, built for their practice.

Delta was born from a simple observation: psychologists spend too much time on administrative tasks, and not enough with their patients.

Our Story

Delta Labs was founded in 2026 in Paris with a simple conviction: AI tools for mental health don't go far enough. Transcribing a session and immediately forgetting it isn't copiloting — it's secretarial work.

Existing solutions paved the way. But they stop at the session door: no inter-session memory, no patient context, no clinical suggestions. They transcribe. Delta understands.

Our bet: building the first cumulative clinical memory for psychologists. A system that remembers what was said six months ago, detects subtle signals, prepares each session like an invisible co-therapist — and improves with every consultation.

This isn't a productivity tool. It's a new way to practice. We believe that in five years, a psychologist without a clinical copilot will be in the same position as a doctor without a digital patient record. Delta is building that infrastructure.

Our Values

What guides every decision.

Privacy first

Your patients' data never leaves France. No audio is retained. Transcription is deleted once the note is generated.

Clinical focus, not noise

Delta doesn't replace the practitioner. It gives them back time and clarity to focus on what matters: the therapeutic relationship.

Simple to adopt

No training required. Delta integrates into your existing practice without changing anything about how you conduct your sessions.

Built for the long term

Delta accumulates value with every session. The more you use it, the better it knows your patients and refines its clinical suggestions.
