Onsen is a free AI mental-health companion built around 'truly remembering you'. You can vent or reflect by text or voice anytime; Onsen turns conversations into journal entries with AI-generated artwork, capturing mood, themes and memories. It ships six AI personalities (The Coach, The Mindful, The Solver and more, or build your own) plus guided experiences such as CBT, meditation and reflection. Validated scales — Oxford Happiness (OHQ-8), Perceived Stress (PSS-10) and Gratitude (GQ-6) — track your state over time, and everything is end-to-end encrypted. Onsen reports roughly 54% of users felt happier within three months and lower stress with use.
Background
Developed by Onsen AI Limited, Onsen is positioned as a non-judgmental, private, always-available mental-wellbeing space that emphasizes externalizing, reviewing and growing from fragmented thoughts rather than replacing professional care.
Technology
A dialogue model delivers personalized insight and emotional support, combined with guided experiences and clinically validated scales; all reflections and interactions are end-to-end encrypted and never shared with third parties, with cross-device sync.
Market
Aimed at C-end users who want regular self-awareness, stress and anxiety relief; per App Store / Google Play data the app has 15,000+ users at roughly 4.5–4.9 stars, with a free tier and Premium subscription.
Best For
People who want to externalize daily thoughts and journal emotionsUsers wanting a private, judgment-free space to talk anytimeThose who like tracking mood with happiness/stress scales long-term
Editorial Note
Integrates AI chat, journaling and validated-scale tracking naturally; the continuous 'remembers you' companionship is its core selling point. But some users find replies generic, more like motivational advice than tailored guidance, and account management needs work.
Strengths
- + Continuous memory + artistic journaling makes externalizing thoughts rare and useful
- + Six AI personalities and CBT/meditation guidance cover diverse self-awareness needs
- + End-to-end encryption with a complete free tier balances privacy and affordability
Drawbacks
- − Some replies feel generic, less personalized than human counseling
- − Account and data management flagged by users as needing improvement
- − Premium price not public; advanced value needs a trial to judge
Value Assessment：Good for those wanting to talk anytime, journal regularly and track mood with scales without paying upfront; it complements rather than replaces professional therapy.
