Seylen: AI Support Companion

This app is not a medical device and does not diagnose, treat, or prevent any condition. Seylen is a quiet place to think out loud — for otherwise healthy people navigating daily stress, and some days are just heavy in ordinary ways.

WHAT SEYLEN DOES

Seylen is an AI companion that listens. Talk about your day, work through something that's been sitting with you, or just check in with yourself — there's nothing to figure out, and no right way to use it.

It holds the threads of your life, so you don't have to start over every time. Seylen remembers what matters to you and brings it back gently, when it's relevant — never as a performance, just as continuity.

Simple mood check-ins let you note how you're doing with a tap, on your own terms. Seylen checks in during challenging moments, too — a soft knock, never a push.

HONEST, ABOUT WHAT IT IS

Seylen is an AI — not a therapist or counselor, and not a substitute for professional care. It's AI-powered support for everyday stress: a companion, not a fix. If you ask, it will tell you plainly that it's AI. Think of it as a space to reflect and reset, alongside whatever other support is right for you — not instead of it.

YOUR PRIVACY, PLAINLY STATED

We don't sell your data, and there are no advertising trackers in Seylen. The AI runs on our own hardware, so your conversations aren't sent to any third-party AI service. Your conversations are encrypted, in transit and at rest.

You can see what Seylen remembers about you, change it, or delete it, whenever you like. Delete your account and everything in it, anytime — the choice is yours.
