Mindsum AI vs Stella - AI Anxiety Companion
Side-by-side comparison · Updated May 2026
| Description | Mindsum AI is a beta version chatbot designed to assist users with mental health-related queries. It provides resources including videos, articles, podcasts, and tips on various mental health conditions such as autism, eating disorders, bipolar disorder, anxiety, OCD, and depression. While it aims to offer useful information, users should note that the chatbot's responses may not always be accurate or reliable. | Stella from Stella Labs is a voice-first AI therapy companion built for everyday anxiety management. Positioned as a thoughtful Woebot alternative launched after the 2025 shutdown, Stella pairs persistent conversation memory with trigger and pattern tracking, emotionally honest reflections, and CBT-inspired daily check-ins to support ongoing growth. Its freemium model lets you start free and upgrade for unlimited voice and full memory—so you can vent at 3AM, track coping strategies, and build a continuous relationship that goes far beyond one-off chats. |
