Stella vs Replika
Anxiety support vs general companionship
Replika is an AI friend for conversation and companionship. Stella is an anxiety-specific mental health companion. Here's how they differ.
Stella
Anxiety-specific AI companion that learns your triggers and patterns. CBT-informed support focused on mental wellness.
Replika
General AI companion for conversations, roleplay, and friendship. Avatar customization and relationship options.
The Key Difference
Replika is designed for general companionship and conversation. It's fun for chatting, roleplay, and having an AI friend. But it's not built for mental health.
Stella is purpose-built for anxiety support. She learns your triggers, applies CBT techniques, and focuses specifically on mental wellness—not entertainment.
