In short
Woebot was a pioneering text-based chatbot from Woebot Health that delivered short, friendly cognitive behavioral therapy (CBT) check-ins and was supported by an early Stanford-affiliated randomized trial. On June 30, 2025 Woebot Health retired the direct-to-consumer app and now reaches people through health plans and employers, so you can no longer just download it. Woebot was a self-help tool, not a replacement for a licensed clinician or a crisis service.
What Woebot is, and what it was built to do
Woebot was a text-based mental-health chatbot created by Woebot Health, a company founded by clinical psychologist Dr. Alison Darcy. Chatbot mental-health experiments date back to ELIZA in the 1960s, but when Woebot launched in 2017 it was one of the first tools to package cognitive behavioral therapy techniques into a friendly, conversational app you could open on your phone whenever you needed it.
The pitch was simple. Instead of waiting for an appointment or working through a self-help book alone, you could chat with a warm, slightly playful AI character that guided you through brief CBT exercises. Woebot was designed as a self-help and emotional-support tool for everyday stress, low mood, and anxious thinking, and it stayed in that skills-coach lane by design.
Important context for anyone searching for it today: in 2025 Woebot Health pulled the consumer app and now works through health plans and employer programs. That means the experience described below is largely the legacy product, and you can no longer just download it.
I used Woebot before it wound down, and it taught me something the whole field keeps proving: a tidy CBT script can help, right up until a real crisis walks in and the script has no answer.
How Woebot worked: CBT and daily check-ins
Woebot's core loop was the daily check-in. It would ask how you were feeling, often with a quick mood rating or a short conversation, and use your answer to suggest a relevant exercise. The whole interaction was meant to take a few minutes, which made it easy to fit into a routine.
The therapeutic backbone was CBT, the well-studied approach built on the idea that thoughts, feelings, and behaviors are linked, and that learning to notice and reframe unhelpful thoughts can improve how you feel. Woebot guided users to spot cognitive distortions such as all-or-nothing thinking or catastrophizing, then practice reframing them in a more balanced way.
Beyond pure CBT, Woebot wove in elements from related approaches such as dialectical behavior therapy and mindfulness, alongside mood tracking and bite-sized lessons. The tone was a defining feature: conversational, encouraging, and a little humorous, which helped lower the barrier to opening up. Woebot used scripted, clinically written content rather than a free-form generative model, so its responses stayed inside guardrails its clinical team had reviewed.
The research behind Woebot
Woebot stood out because it launched alongside published research, which was unusual for a consumer mental-health app. The foundational study, by Kathleen Kara Fitzpatrick, Alison Darcy, and Molly Vierhile, appeared in JMIR Mental Health in 2017 and was conducted with a Stanford-affiliated team.
That randomized controlled trial enrolled young adults who reported symptoms of depression and anxiety. One group used Woebot for two weeks, while a comparison group was directed to a self-help ebook about depression. The Woebot group showed a meaningful reduction in depressive symptoms, measured with the PHQ-9, compared with the control group, and engagement with the chatbot was high.
This early evidence was genuinely important for the field, but it is worth keeping in perspective. It was a small, short trial in a non-clinical sample, and it tested an early version of the product. Over the following years Woebot Health published and contributed to further research, yet the broader evidence base for chatbot-delivered CBT remains early; our overview of AI therapy studies covers what the research actually shows. The honest summary is that studies suggest these tools can help some people with mild symptoms, not that they treat or cure mental illness.
Strengths and limits
Strengths. Woebot was clinician-built, grounded in CBT, and unusually transparent about its research. It was free to the user for most of its consumer life, available around the clock, and easy to talk to thanks to its warm, low-pressure tone. For someone curious about CBT skills or wanting a structured nudge between therapy sessions, it was a thoughtful, low-risk place to start. Because its content was scripted and reviewed instead of open-ended, it was also less prone to the unpredictable replies that can come from purely generative chatbots.
Limits. The scripted approach that kept Woebot safe also made it feel rigid at times, since it could not follow every twist of a real conversation the way a person, or a modern large language model, might. It was a self-help aid, not therapy, and not a crisis service. It did not diagnose conditions or build a personalized treatment plan, and the supporting research, while pioneering, was early and limited in scope. The biggest limit today is simply access: the consumer app is gone, so most people can no longer download and use it the way they once could.

What happened in 2025: the shift away from a consumer app
Woebot Health retired its direct-to-consumer chatbot on June 30, 2025 and shifted its focus toward clinical and partner channels. Founder Alison Darcy pointed to two reasons: the cost of pursuing FDA marketing authorization for a prescription version, and the rise of large language models that the FDA had not yet figured out how to regulate. In practical terms, the standalone Woebot you may have read about in older reviews is no longer broadly available to download and use on your own.
There is no consumer price to quote: access now runs through healthcare and enterprise partners, not an app store listing. If you specifically want Woebot, check Woebot Health's own website for the current status before assuming you can still access it directly.
This shift mattered for the whole category. Woebot was a flagship example of a research-forward consumer mental-health chatbot, and its retreat showed why building an AI therapist is so hard, even with strong clinical credentials and published evidence.
Legacy and alternatives
Woebot's legacy is real. It helped prove that a friendly chatbot could deliver structured CBT skills, paired a consumer app with peer-reviewed research, and set an expectation that mental-health tools should be evidence-informed rather than purely promotional. Many of the apps people use today were shaped by the trail it cut.
If you came here looking for a Woebot-style experience and cannot access it, there are active alternatives that lead with CBT or DBT. Wysa is one of the most established, built around CBT and DBT exercises with a free core chat and optional human coaching. Ash leans toward open-ended, reflective conversation if you mainly want to talk something through. For a fuller side-by-side of current options, see our roundup of the best AI therapy apps. Our guide to reading AI therapist reviews explains how to weigh user ratings when comparing them.
Whichever tool you try, treat it the way Woebot was always meant to be treated: as a skills coach for practicing CBT and tracking mood. If your symptoms are serious or persistent, or if you prefer working with a person, browse licensed therapists in our directory.

Frequently asked questions
Is Woebot still available?
Not as a consumer app. Woebot Health retired the direct-to-consumer app on June 30, 2025 and refocused on clinical and partner channels, so the standalone app most people used can no longer be downloaded. Check Woebot Health's website for the current status.
How does Woebot work?
Woebot worked through short, conversational daily check-ins. It asked how you were feeling, then guided you through brief cognitive behavioral therapy exercises, such as spotting and reframing unhelpful thoughts. Its responses were scripted and clinically reviewed instead of fully open-ended, which kept the experience inside safe, tested guardrails.
Is Woebot an AI therapist?
No. Woebot was an AI-driven self-help chatbot that delivered CBT-based skills and check-ins. It stayed a skill-building and emotional-support aid; diagnosis, treatment plans, and crisis support remained the job of licensed professionals and services like the 988 Lifeline.
Is Woebot backed by research?
Yes, more than most consumer apps. A 2017 randomized controlled trial by Fitzpatrick, Darcy, and Vierhile in JMIR Mental Health, conducted with a Stanford-affiliated team, found that young adults who used Woebot for two weeks had a meaningful reduction in depression symptoms compared with a control group. The study was small and short, so it counts as promising early evidence, not proof of long-term benefit.
What are good alternatives to Woebot?
If you want a CBT-focused experience similar to Woebot, Wysa is one of the most established options, with CBT and DBT exercises and a free core chat. Ash suits open-ended, reflective conversation.
