Sonia is built for long-term emotional wellbeing. It remembers what you share, recognizes patterns over time, and turns reflection into insight, next steps, and a support plan that's actually tailored to you. The more you talk, the more it understands your story - your goals, your habits, and the kind of care and emotional support that actually helps.

How is Sonia built?

Most AI was built for general conversation. Sonia was built specifically for mental health, self-help, and emotional wellbeing. Our AI is trained with expert-guided feedback, cognitive-behavioral principles, evidence-based reflection, mindfulness, and human psychology - so it can help you reflect, process, and build healthier coping strategies.

The team behind Sonia

Sonia is designed with licensed therapists, mental health leaders, coaches, researchers, and engineers from Stanford, MIT, ETH, and beyond. Our team brings psychology, safety research, and AI engineering together into a private support experience you can use any time. We're on a mission to make personalized, high-quality mental health support available to everyone.

What can you use Sonia for?

  • Talk through stress, anxiety, relationships, family problems, conflict, motivation, procrastination, or a difficult day
  • Speak freely in a private, non-judgmental conversation by voice or text - like talking to an AI coach who actually listens
  • Build a personalized support plan based on your goals, patterns, and needs
  • Reflect with journal prompts, mindfulness exercises, meditations, and weekly insights
  • Get emotional support, life coaching, accountability, encouragement, and perspective when your mind feels loud
  • Invite your partner into guided couples sessions to work through relationship challenges together

Testimonials

  • "Daily use is helpful instead of stressful. I am genuinely impressed with Sonia's ability to challenge me instead of falling into a sycophantic rut."
  • "As someone going to therapy I must say Sonia is understanding, validating, and insightful. I felt heard, processed what I was feeling, and learned more about myself."
  • "It is so helpful to have an unbiased voice listen whenever I need. I did not realize how much I needed to get off my chest until I started talking."

Sonia is designed for adults 18+. Sonia is AI-based and you are not talking to a licensed human therapist, psychologist, or doctor. Sonia can make mistakes and should not be used as a replacement for professional medical care, diagnosis, or treatment. Interaction with Sonia does not create a medical professional-patient relationship.

Sonia is not designed to be used in crisis. If you are in crisis, please seek out professional help or a crisis line. You can find resources at www.findahelpline.com.
