Sonder is a supportive, AI-powered tool in your SonderMind app that helps you stay connected to your therapy work between sessions. It’s not therapy or a therapist — it’s a guided space to reflect, practice coping skills, and organize your thoughts in a safe, private way.
Sonder is available to SonderMind app users age 18 and older, excluding anyone residing in Illinois.
Many people already use AI tools to talk through emotions or get support. Sonder gives you a safer, clinically-guardrailed alternative designed to support your continuous care journey — especially between therapy sessions— with clear boundaries, strong privacy protections, and built-in safety guardrails. And while Sonder was built with active therapy clients in mind, we know it’s a valuable tool no matter where you are on your wellness journey, including for those who are not in active therapy sessions.
Sonder can help you:
It's designed to supplement your therapy journey, as additional support for the days between active time with your clinician -- especially on days when live feels overwhelming or busy.

Not at this time. In the future, we may create an option for you to share messages with your provider. At this time, you are always welcome to bring your Sonder experiences into your next session.
Sonder will show emergency resources if you express you are unsafe or in danger. However, it cannot assess risk or provide crisis support itself.
If you are in crisis, call 988 or your local emergency number.
Sonder adheres to SonderMind AI Constitution, our framework for building safe, clinically aligned, and privacy-protected AI tools:

No. Sonder is designed to support therapy, not replace your therapist or the clinical care you receive. It helps you stay connected to the work you’re already doing and supports you between sessions — but real therapeutic progress still happens with your licensed provider.
To start using Sonder, you will need to download the SonderMind app from the App Store or Google Play. Sonder will greet you at the top of your home screen. Just tap into the chat bar to start exploring, reflecting, and practicing new skills at your own pace.
Users can turn off Sonder at any time - or turn it back on - using a toggle switch located in Account Settings > Login & Security. See image below.
