Tell it what's stressing you
No need to phrase it well. Write it the way it comes out — Serein understands and never judges.
Untangle it together
Serein helps you separate fear from reality: what's the realistic worst case? What do you stand to gain?
Leave with one small step
Every conversation ends with a simple, doable action. Small wins push anxiety back.
Your conversations are never sold or used for advertising
Talking about anxiety takes trust. The essential proofs come first; open any item when you want the detail.
+No ads, everYour conversations stay private
Serein doesn't sell your conversations and shows no ads. They're kept only so you can find them again from one session to the next.

Serein never diagnoses and never discusses medication. In case of serious distress, it points you to real human resources (988, Crisis Text Line, 911).

SereinFrequently asked questions
Does Serein replace a psychologist or a doctor?+
No. Serein is a wellness companion: it helps you step back from everyday anxiety, but it doesn't diagnose, doesn't give medical advice, and doesn't replace a health professional. If anxiety keeps you from functioning, talk to a professional.
Are my conversations private?+
Yes. Your conversations are never sold or used for advertising. They're kept only so you can pick them up from one session to the next, and you can download them or delete everything from your account in one click.
How much does Serein cost?+
The Discovery plan is free forever (10 messages a day, no credit card). The Sérénité plan offers unlimited conversations at $14.99 USD per month or $99 USD per year, with a 7-day free trial.
Can I cancel my subscription?+
Yes, anytime, right from your account. Cancellation takes effect at the end of the period you've already paid for, with no hidden fees.
What if I'm in serious distress?+
Serein is not an emergency service. In the US and Canada, call or text 988, the Suicide & Crisis Lifeline (24/7). Or text HOME to 741741. If you are in immediate danger, call 911.
Serein is a wellness companion, not a caregiver.
Serein doesn't diagnose, doesn't give medical advice, and doesn't replace a psychologist, a doctor, or an emergency service. If anxiety keeps you from functioning day to day, talk to a health professional.
