Woebot Health is a mental health AI company founded by clinical psychologists from Stanford, with a distinctive commitment to clinical evidence — publishing randomised controlled trials demonstrating Woebot's effectiveness for depression and anxiety reduction. This research foundation positions Woebot alongside traditional clinical mental health interventions rather than as a consumer wellness app.
Woebot provides CBT techniques through conversational AI — rather than presenting CBT as a workbook or course, Woebot engages users in conversation about their current emotional state and guides them through relevant CBT techniques in dialogue format. The conversational delivery increases engagement and personalises which techniques are presented based on the user's reported experience.
The RCT evidence is Woebot's most important differentiator. The 2017 RCT published in JMIR Mental Health showed statistically significant reductions in depression and anxiety among Woebot users versus a control group in a 2-week study. Subsequent research has continued to evaluate Woebot across populations and conditions, building an evidence base that most mental health apps lack entirely.
Woebot for Health is the clinical product deployed by health systems, insurance plans, and employer benefits programmes as a scalable adjunct to professional mental health care — extending CBT access to patients on waitlists, between sessions, or in settings without sufficient therapist capacity.
Woebot Health runs as conversational ai agent software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on ios, android, and web, with API access for teams that want to embed it into their own products.
