ENG: Anima is an innovative neurotechnology platform for psychological assessment and mental health support. We combine web-based technology, evidence-based psychology, and neurobiology to deliver objective, personalized insights into a person's emotional and cognitive state through eye movement analysis. Our expertise lies in integrating science and technology. Anima uses attention bias assessment and eye-tracking to capture unconscious visual responses to emotionally charged stimuli. This enables the early detection of anxiety, burnout, and cognitive fatigue before these conditions manifest behaviorally. We have field-proven results. Anima is already used by thousands of individual users and is currently being tested in medical and corporate environments. We also participate in international innovation support programs such as Brave1 and Seeds of Bravery. We help organizations make mental health support part of everyday work.

Це дозволяє виявляти ранні ознаки тривожності, вигорання та когнітивного виснаження ще до того, як вони стануть помітними у поведінці. Ми маємо підтверджені результати.
