A living anime character on your Mac. She hears you*, answers in her own voice with real lip-sync*, emotions, gestures and runs 100% offline, no tracking.
* Premium
Kavaii — She lives on your Mac. Not in the cloud.
Kavaii is a 3D anime AI that runs entirely on your Mac. Nana sees you*, hears you*, talks back in her own voice*, and moves on her own — fully offline, fully private.
What no other app does
One living 3D character, and everything runs on your machine: you talk to her out loud and she hears your real voice — not a transcript — she sees through your camera, answers in her own voice with real lip-sync, and thinks entirely on-device. That whole combination, offline, is Kavaii.
Talk to her — hands-free.*
In Free Flight you just speak: no typing, no buttons. Your voice goes straight into the model as audio — never turned into text first — so she catches your words, your tone, your mood, even the sounds around you. Real hearing, not speech-to-text. Say as much as you like; a natural little beat before she answers is the rhythm of a real conversation, not an instant chatbot.
She sees you too.*
Switch on the camera in Free Flight and a snapshot goes with each thing you say — so she reacts to what's actually in front of her. Share a photo any time and she takes it in and talks about it with you.
She understands sound, not just speech.*
Drop in an audio file and she hears all of it — voices, music, instruments, background, mood. Ask her to transcribe a voice memo, translate it, summarize it, or name the track that's playing. Real multimodal audio, on your Mac.
Her own voice, real lip-sync.*
Seven in-house voices, mouth moving in sync with every word: German, English, Spanish, French, Italian, Portuguese, Russian. Text chat in 50+ more languages.
A mind of her own.
Nana moves, glances and gestures on her own — no scripts, no buttons to pose her. How she acts depends on how you treat her. Pick her personality (Sweet, Cheerful, Calm, Playful, Loving), rename her, and step into a soft 3D meadow where she walks, and dances.
Tuned to your Mac.
Three on-device models: a light one that's fast on modest Macs, a balanced 4B for thoughtful conversation, and a large Mixture-of-Experts model (26B-A4B) for demanding topics and document analysis. Kavaii recommends the best fit for your machine. Native animation written from scratch — no game engine — so she can live on your desktop all day.
100% offline. 100% private.
No accounts. No servers. No telemetry. Chats, voice and images stay on your Mac and never leave it. The only time Kavaii goes online is a one-time model download. Try it: turn off Wi-Fi mid-conversation — Nana doesn't even notice.
Kavaii is a 3D anime local AI simulation for entertainment. Rated 16+.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Kavaii is now free to start. Open the app and chat with your on-device anime character right away — no subscription needed for text chat.
New in this version:
• Free tier: full text chat with your 3D character — her movement, gestures, expressions and the living scene are all included, free.
• Premium features you can unlock anytime: her spoken voice, Free Flight (hands-free live voice conversation), image and audio input, the camera, and a larger conversation memory.
• A more alive garden: flowers and tree canopies now sway gently in the wind, and the scene glides through a smooth sunrise-to-sunset transition with a real moon at night.
• More natural animation: her lip-sync now follows the actual voice, and her gestures while speaking feel more lifelike.
• Smoother than ever: sending a message no longer causes the scene to stutter, and the app stays responsive throughout.
Everything still runs 100% on your Mac — offline, private, no account, no cloud.
