AI is changing what mental health apps can do. Here are six apps using AI thoughtfully in 2026, compared on features, privacy, and what they actually deliver.
By Omar Rantisi, Founder of Therma
AI in mental health is still early, and a lot of apps are slapping "AI" on basic features. We focused on apps where the AI does something meaningful: pattern recognition, adaptive prompts, conversation. We weighted privacy heavily because mental health data deserves it. And we gave bonus points for clinical input or transparent limitations.
Therma uses AI to find patterns in your daily check-ins and reflect them back as weekly insights. It's not therapy, doesn't pretend to be, and is upfront about its limitations. The integration with Oura, Apple Health, and other wearables is the differentiator. End-to-end encrypted. Disclosure: our app.
Pros
Cons
Wysa is one of the most clinically validated AI chatbots in mental health. Built with input from therapists, it uses CBT techniques to help users work through anxiety and low mood. It's reached 6 million users, has peer-reviewed research, and has been used in NHS pilots in the UK.
Pros
Cons
Woebot is built by a team of clinicians and researchers led by Stanford's Dr. Alison Darcy. It uses CBT, IPT, and DBT techniques in short daily check-ins. Has the strongest clinical research base of any consumer mental health AI.
Pros
Cons
Replika is the most-used AI companion app, but it's designed for companionship, not mental health. It can be useful for loneliness and casual conversation, but it's not built with clinical input and shouldn't be relied on for mental health support.
Pros
Cons
Youper combines mood tracking with AI-guided CBT exercises. It's well-designed and clinically informed, sitting between a chatbot and a journal. Less ambitious than Wysa or Woebot, more substantial than basic mood trackers.
Pros
Cons
Reflectly uses AI for prompt selection in a journaling context. It's the original AI journaling app (2017) and remains polished and mature. The AI is template-driven rather than truly adaptive, but the prompts are well-curated.
Pros
Cons
For AI mental health apps specifically, we weighted clinical credibility, privacy practices, and the actual sophistication of the AI heavily. We tested each app over multiple weeks and looked for transparency about limitations. None of these apps are therapy substitutes and none should be your only mental health resource if you're in distress. Therma is disclosed as our own product. Pricing is current as of April 2026.
AI mental health tools can be useful for self-awareness, structured exercises, and pattern recognition. They are not safe as a replacement for professional care, especially for serious conditions or crisis situations. Use them as a complement, not a substitute.
Wysa and Woebot have the strongest peer-reviewed research support. Both were built with input from licensed therapists and have been studied in academic settings.
No, and reputable apps don't claim to. AI tools work best for ongoing self-awareness, structured exercises, and pattern recognition between sessions. For diagnosis, treatment of conditions, or crisis support, you need a human professional.
Read the privacy policy. Look for end-to-end encryption (which means even the company can't read your entries), clear data retention policies, and HIPAA compliance for health-related apps. Therma uses end-to-end encryption by default. Wysa and Woebot are HIPAA-aligned. Replika has had privacy controversies and should be approached with caution.
Neither is actually a therapist. AI companions (like Replika) are designed for general conversation. AI mental health apps (like Wysa or Therma) are designed with clinical or research input for self-awareness and structured reflection. Neither replaces a licensed clinician.
