A moment to notice how you feel
Your two-week check-in.
Over the last 2 weeks, how often have you been bothered by any of the following problems?
PHQ-9 · 9 questions · answers stay in this browser tab. This is a screening questionnaire, separate from the research prediction model. You can stop or clear it at any time.
Your questionnaire result
The score describes a symptom range, not a diagnosis. Even a low score does not rule out distress or a need for support. A clinician considers your circumstances, functioning and history too.

A question is enough to start
MoodDot
Supportive information, not therapy or emergency care.
Checking service status…What would you like to ask MoodDot?
You can keep it short. You don’t need to share your name or personal details.
If you may hurt yourself or cannot stay safe, please seek immediate human help rather than waiting for AI.
Immediate support →Human support, now
You do not have to handle this alone.
If you may act on thoughts of harming yourself, have already harmed yourself, or cannot stay safe, contact your local emergency services or go to the nearest emergency department.
If possible, ask someone you trust to stay with you while you get support. This website and MoodDot are not monitored emergency services.

About this space
Research details & privacy
Three separate tools
The PHQ-9 questionnaire, research model and MoodDot are independent. Questionnaire answers and measurements are not automatically passed to AI.
Research model, score and limitations
Each route uses 25 saved models with their own training-side thresholds. The full-input route includes both Q0 and Q1 models. The combined website rule has not been independently validated.
MoodDot and privacy
MoodDot provides information, not clinical care. Messages and any result summary you choose to share go to the external AI processor. No live AI connection has been verified. External processor information
This local application does not persist uploads, questionnaire answers or chats. Browser, network and service providers can have their own traces; this is not a secure-erasure guarantee.
Sources and input definitions
Annual household income uses fixed approximate consumption-PPP bands where a verified profile exists. In other regions, income is not requested and the frozen missing-value rule applies. The conversion is not an internationally validated clinical threshold. CSV/XLSX/JSON files must follow the project template, not a raw instrument format. Entry guards are not study inclusion criteria.
