Headspace just added "Ebb" AI in December 2025. Here's how it compares to Stella's voice-first approach.
Voice-first AI conversations built for anxiety. Talk through what's happening—Stella remembers your patterns and responds in real-time.
Meditation library with 500+ guided sessions. New "Ebb" text-based AI companion added December 2025.
Headspace built their reputation on meditation content—a vast library of guided sessions, courses, and exercises. In December 2025, they added "Ebb," a text-based AI companion as a new feature.
Stella was built from day one as a voice-first AI companion for anxiety. You talk out loud, Stella listens and responds, remembering your triggers and what works for you.
"Headspace's Ebb validates the AI companion space—but it's text-based and brand new. Stella is voice-first and purpose-built for anxiety conversations."

Headspace adding Ebb AI in December 2025 validates the AI companion space for anxiety. They saw what works and built their own version.
But here's the difference: Ebb is text-based and brand new—a feature added to a meditation app. Stella is voice-first and purpose-built for anxiety conversations from the ground up.
Headspace excels at meditation content and building daily habits. If that's what you need, they're excellent at it. Their AI companion is an experimental add-on.
Stella is designed for people who need to talk through anxiety—out loud, in the moment, with an AI that remembers you. That's not an add-on feature for us. It's the whole point.
Both apps now offer AI companions. Here's how they differ:
Stella:
Voice-first. You talk, Stella listens and responds with voice.
Ebb:
Text-based. You type messages back and forth.
Stella:
Deep memory system. Learns patterns, triggers, what works for you over time.
Ebb:
Limited personalization. New feature (launched Dec 2025), still developing memory capabilities.
Stella:
Core product. Every feature built around AI conversations.
Ebb:
New add-on feature to meditation app. Still finding its place in the product.
