The method

Science-first. Only techniques backed by real evidence.

Cognitive Behavioral Therapy (CBT) is the branch of psychology with the strongest empirical evidence for anxiety, insomnia and stress. Deepfriend translates it into a thoughtful conversational experience, supervised by a CBT psychologist.

01

Designed with a CBT professional

Every flow and technique is reviewed by Adrián González, a psychologist specialized in cognitive behavioral therapy.

02

Published methods

Cognitive restructuring, gradual exposure, sleep hygiene, clinical mindfulness. Everything is traceable to scientific literature.

03

No magic promises

Deepfriend accompanies; it doesn't replace therapy. We give you tools, your own pace, and honesty about our limits.
