Frequently Asked Questions

Are AI therapy apps effective?

Several AI therapy apps have demonstrated clinical effectiveness in peer-reviewed research. Wysa has 30+ published papers showing significant reductions in anxiety and depression symptoms. Youper has a Stanford-validated study (N=4,517) showing meaningful symptom improvement. However, AI therapy apps are not substitutes for professional treatment, especially for severe mental health conditions. They work best as supplements to therapy or for mild-to-moderate symptoms.

What happened to Woebot?

Woebot permanently shut down its consumer app on June 30, 2025, citing FDA regulatory burden and costs. The company pivoted to an enterprise-only B2B model, selling to health systems and payers. Consumer users lost access and account data was anonymized by July 31, 2025. Wysa and Youper are the leading alternatives for consumers who previously relied on Woebot.

Which AI therapy app has the most clinical evidence?

Among currently available consumer apps, Wysa leads with 30+ peer-reviewed publications including RCTs in JMIR. It is endorsed by the UK NHS and CE-marked as a Class I medical device in the EU. Woebot had 14+ RCTs but is no longer available to consumers.

Is Replika a therapy app?

No. Replika is an AI companion focused on emotional connection and relationship building, not structured clinical therapy. It uses CBT-informed mood coaching but is not designed as a clinical tool, has no peer-reviewed RCTs, and has faced FTC complaints about deceptive marketing to vulnerable users. It should not be used as a substitute for professional mental health treatment.
