**Your thoughts stay on your phone.** KinetSoul is an AI emotional companion that runs **fully offline by default**. Talk through your day, track your mood, and feel heard — without your most private conversations ever leaving your device. No account. No login. No tracking. No ads. No backend servers. ### Why we built this Every major AI companion — Replika, Character.AI, Pi, the rest — is a cloud service. That means your most intimate conversations are on someone else's server by architecture, not by choice. We didn't think "private mode" was good enough. So we built KinetSoul with **no backend to receive your data in the first place**. ### What it does 🗣️ **Talk it out** — Chat with a companion that listens and responds with warmth. Speak or type. Switch between on-device models to find the voice that fits you. 🌊 **Track your mood** — A quick daily check-in becomes a gentle mood wave over time, so you can see the shape of your feelings. 🧠 **It remembers you** — Long-term memory quietly notes what matters to you. The more you talk, the better it understands your emotional rhythms — not starting from scratch every time. 🎙️ **Voice companion** — Talk hands-free, and have replies read aloud when you want company you can hear. 👤 **Looks like you** — Pick avatars for yourself and your companion, from warm presets or your own photos. ⚙️ **Your model, your rules** — Switch between built-in on-device models (Qwen2.5 3B, ~1.9 GB, runs offline), or connect your own remote AI key. Your data, your model, your rules. ### Private by design — not by promise - ✅ Companion AI runs **fully offline by default** - ✅ **No account, no login, no tracking, no ads** - ✅ Moods, chats, and memories stay on your device - ✅ Optionally connect your own remote AI — only with your explicit consent do messages go directly from your device to the provider you chose. **We never see, store, or relay your data.** ### Not a substitute for professional care KinetSoul is a companion for everyday feelings and reflection. It is not a medical or mental-health service and does not diagnose or treat any condition. If you're struggling, please reach out to a qualified professional or a local helpline. Works in English, 简体中文, 繁體中文, and 日本語.

this offline-first angle is genuinely refreshing, love that my journal entries aren't floating around somewhere. one thing i'd love is a simple export to plain text or pdf option, kind of like a yearly mood recap you can save locally. that way even if the app changes or you switch phones, your history stays yours without depending on anything external.

Offline-first is a huge win for something this personal, and the lack of any account setup made it feel immediately safe to actually open up.

the fully offline by default approach is genuinely thoughtful, especially for something this personal. love that there's no account or login friction either, just open and talk.
