Features
Voice-first support
that actually remembers.
Designed for the moments when text doesn't cut it. Stella learns your patterns, your triggers, and what actually works.
What makes Stella different from other AI companions?
Stella is the only AI companion with persistent memory. Unlike ChatGPT, Claude, or other AI chatbots that forget you after each conversation, Stella remembers your triggers, what worked last time, and your anxiety patterns. Stella also offers voice-first conversations (not just text), 24/7 availability, and proactive check-ins when you need support most.

She knows your life. She has your back.
Text Stella like you'd text a friend. She lives in the conversation you're already having. Voice when you need to talk.
Daily check-ins, gentle nudges, no nagging. Stella reminds you to breathe, to eat, to step outside — the things you forget when life gets heavy.
Your triggers, your patterns, what worked last time. Every conversation builds on the last.
Oura Ring, Apple Watch — Stella reads your sleep, HRV, and activity to understand how you're really doing.
Stella knows you have a hard meeting at 2pm and you slept 4 hours. She doesn't push harder. She helps you handle today.
End-to-end private. Stella doesn't share, sell, or judge. Your conversations stay yours.
Voice
A voice that
actually listens.
Sometimes typing isn't enough. Stella's voice feature lets you speak naturally and be met with calm, understanding responses — just like a real conversation. Voice when you need to talk. Text when you can't. Always adapting.
Memory
Finally, someone
who gets it.
Stella learns your patterns, your triggers, what actually helps — so you never start from zero. Before you spiral about that text, talk to someone who remembers your overthinking patterns from last time.
Availability
24/7. No
office hours.
2am spiral. Sunday scaries. Pre-meeting panic. Stella doesn't have office hours. Talk when you need it, not when a therapist is available.
The AI that actually knows you.
Start with one text. She'll take it from there.
