Stella vs Replika
Talking it through vs companionship
Replika is an AI friend for conversation and companionship. Stella is your emotional wellness AI, for talking through what happened. Here's how they differ.
Stella
Your emotional wellness AI. Tell her what happened, by voice or text. She keeps what you've told her in mind, tells you straight but kindly, and helps you find the words when you're ready.
Replika
General AI companion for conversations, roleplay, and friendship. Avatar customization and relationship options.
