Luther
Free mental health tests online
These are the questionnaires clinicians use for screening, in the public domain or free to use with attribution. A score is not a diagnosis — only a person can give you that. In the Luther app each result also comes with a personal reading and is kept so you can see how it changes.

A score is a number. What does it mean for you?
In Luther the same questionnaire comes with a personal reading: what your answers point to, what has changed since last time, and what is worth trying next. Your first day is free, with no card.
Your answers stay in this browser. Nothing is sent anywhere, and nothing is saved.
Luther is an AI companion for everyday support. It is not therapy, not medical care and not a diagnosis. If you are thinking about harming yourself, please do not wait: call your local emergency number, or find a helpline for your country at findahelpline.com.
