Meet ZOSA. Your private artificial intelligence companion for mental wellbeing, growth and self-reflection. Anonymous by default. End-to-end encrypted. Available whenever you need it. Whether you are navigating stress, processing complex feelings, or simply seeking to understand your own mind more clearly, ZOSA provides a secure, judgement-free space to explore your thoughts. Most mental health apps are free because your data isn't. BetterHelp was fined $7.8 million for sharing therapy conversations with Facebook and Snapchat. Headspace and Calm have both received privacy warnings from Mozilla. ZOSA works differently: your conversations are anonymised, encrypted, and never used to train artificial intelligence models or target you with adverts. Features • Intelligent Chat: Thoughtful, continuous conversations that adapt to you. ZOSA builds meaningful context across your sessions, available 24/7, without judgement. • Voice Mode: Speak freely. ZOSA listens in real time, responding naturally so you never have to type a word. • MindGraph: A living map of your emotional patterns and recurring themes. Watch your inner world evolve across sessions, turning scattered thoughts into genuine self-awareness. • ZoSecure Encryption: Military-grade encryption applied directly on your device. Zero-knowledge architecture: we cannot read your conversations, even if we wanted to. • Journey Dashboard: Your sessions, emotional patterns, and next steps, organised in one clear, minimal space. • Guided Programmes: Over 90 self-guided courses covering anxiety, confidence, burnout, sleep, grief, relationships, and more. Grounded in therapeutic research, built to fit your life. • Deep Insights: Personalised reflections drawn from your unique journey. Patterns you hadn't noticed. Moments to pause and recalibrate. • Notes and Appointments: Capture thoughts, securely scan handwritten journal entries, and manage your wellbeing schedule, all in one place. • Neurodivergent Support - Tailored experiences for ADHD, autism, and sensory sensitivities. Membership Free to get started. Upgrade to ZoPlus or ZoPro to unlock advanced artificial intelligence, unlimited sessions, real-time voice, deeper analytics, MindGraph, and long-term memory. "We believe the most meaningful support comes from the people around you. But not everyone can access that, whether it's cost, waiting lists, or simply not being ready. ZOSA exists in that space: a private, intelligent companion available whenever you need it. We hope it helps in your journey." - The ZOSA Team Privacy and Safety Your privacy is not a feature, it is the foundation. Conversations are anonymised by default. ZoSecure encryption means only you can access your data. Nothing is sold, shared, or used for advertising. Delete everything in one tap. Please note: ZOSA is designed for support, reflection, and personal growth. It is not a substitute for professional mental health care.
