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.

Built for the moment it actually matters.
Talk it out. Voice when you need to vent. Text when you can't speak. Stella meets you where you are.
24/7 support. No office hours, no waiting lists, no judgment.
Stella remembers your triggers, patterns, and what worked last time.
Stella notices shifts in your patterns and checks in — before you even realize you need it.
Your anxiety has patterns you can't see mid-spiral. Stella tracks them so day 30 is better than day 1.
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.
You don't have to do this alone.
Stella's ready when you are.
