A mental health chatbot needs more than engaging conversation. Its intended population, evidence, privacy practices and route to human help should be clear before use.
Recognize the intended role
Wellness journaling, symptom screening, clinician support and treatment are distinct uses. Ask what the product is designed to do, which ages it supports, who supervises care and whether a trained person can respond when someone needs help. A conversational tone does not establish clinical competence.
Read the comparator carefully
The 2025 Therabot trial randomized 210 adults to a four week specialized chatbot intervention or a waitlist. Symptom reductions favored the intervention through eight week follow up. It did not compare the chatbot directly with a human therapist, and its results do not validate general chatbots or use by children. Read the trial.
Questions before using a service
- Who can read conversations, how long are they retained, and are they used for model training?
- What happens when the system gives harmful advice, misunderstands someone or misses a crisis?
- Is escalation actually staffed, and what are its hours and response times?
- Does the evidence report dropout, worsening symptoms and adverse events as well as improvement?
- Can users leave the service and obtain human care without pressure to keep chatting?
Keep human care accessible
Discuss a tool with the treating clinician when it is intended to support care. Do not let a chatbot decide whether professional care is needed or replace an agreed treatment plan. A product should explain its limitations in language a person under stress can understand.
If help is urgent
In the United States, call or text 988 for suicidal crisis or emotional distress. For a life threatening emergency, call 911 or go to an emergency department. Outside the United States, use local crisis and emergency services. Use human emergency support rather than waiting for a chatbot response. NIMH help resources.
