Which AI mental health app is «the best»? There is no universal answer. These tools serve different purposes and the evidence behind them varies. This guide focuses on what each app does, what evidence exists, and what users should check before relying on AI for mental health support.

Important: AI mental health apps are not a substitute for emergency care or a qualified professional. If you may harm yourself or someone else, contact your local emergency service. In the U.S., call or text 988. In Spain, call 024.

Which App for Which Need?

App	Best suited to	Evidence snapshot	Status
Wysa	Structured self-help for stress, anxiety and low mood	Peer-reviewed trials and other published research; a comparatively broad published evidence base	Available
Earkick	Daily mood check-ins and tracking	Independent clinical evidence remains limited	Available
Ash	Open-ended supportive conversation	Recent real-world observational studies; no randomized treatment trial established	Available
Ebb (Headspace)	Self-reflection and emotional support within Headspace	Safety testing and product research; not intended as clinical treatment	Adults 18+ in the U.S., U.K., Canada and Australia, depending on Headspace membership and access

Evidence strength varies considerably between products. Published research on one AI mental health app should not be interpreted as evidence that other apps provide the same benefits or safety profile.

This is a guide to fit, not a ranking. Check the provider’s current information before signing up.

The Apps in More Detail

Wysa: structured self-help

Published research

Wysa uses conversational support and exercises based on approaches such as cognitive behavioral therapy and mindfulness. Its clinical evidence page lists peer-reviewed research. Wysa also reports an FDA Breakthrough Device Designation for an AI-led mental health conversational agent. That designation is not FDA marketing authorization or proof that the app replaces clinical care.

Earkick: mood tracking

Limited independent evidence

Earkick focuses on daily check-ins, mood tracking and conversational support. That can help users notice patterns over time. Independent clinical evidence remains limited, so it is better viewed as a wellbeing and tracking tool than as a proven treatment.

Ash: open conversation

Observational evidence

Ash offers free-flowing conversations designed around mental wellbeing. A 2026 observational study of 1,284 new users reported improvements in life satisfaction, sleep, relationships and behavioral activation over four weeks. As a single-arm observational study, it cannot establish that Ash caused those changes. That distinction matters when comparing AI support with clinical treatment.

Ebb: for Headspace users

Not clinical treatment

Ebb is Headspace’s AI companion for self-reflection and personalized recommendations. Headspace says Ebb does not diagnose or treat mental health conditions and is not a substitute for human care. Ebb is currently available to adults aged 18 and over in the U.S., U.K., Canada and Australia, with availability depending on Headspace membership and access.

What Does the Evidence Say?

The strongest recent clinical trial concerns Therabot, a research chatbot rather than a public consumer app. In a 2025 randomized trial published in NEJM AI, 106 participants used Therabot and 104 were in a waitlist control group. After about four weeks, Therabot users showed significantly greater reductions in symptoms of depression, generalized anxiety and clinically high-risk feeding and eating disorder symptoms than the waitlist group.

What the trial shows

A randomized comparison with a waitlist group
Greater symptom reductions with Therabot after about four weeks

What it does not show

The comparison was with a waitlist, not psychotherapy
High-suicide-risk participants were excluded
It does not prove that commercial AI apps provide equivalent therapy

Privacy and Safety: What to Check

Match the tool to the need.
Look for evidence about the exact product. One chatbot’s study does not validate another.
Read the privacy policy. Check storage, data use, processing and deletion.
Check crisis safeguards. AI is not an emergency service.
Keep access to human care. Persistent or worsening symptoms deserve professional attention.

Two Names You May Still See in Older Lists

Youper discontinued its services on September 30, 2026. Woebot retired its consumer app on June 30, 2025; new accounts can no longer be created and previous accounts cannot be accessed.

The Bottom Line

There is no single AI mental health app that fits everyone. The evidence is uneven across products. Wysa currently has a comparatively broad published research base, while Earkick focuses mainly on tracking, Ash has emerging observational evidence, and Ebb is positioned primarily as a self-reflection and wellbeing tool. None replaces a licensed therapist or emergency service. Check the evidence and privacy practices of the exact product, and use AI support as a supplement rather than a replacement for human care.
