Kavaii
3D Anime local AI Simulation
Only for Mac
Free · In‑App Purchases
Mac
A living 3D character on your Mac — never in the cloud. Private, offline, and free to chat with forever. One purchase adds her voice and eyes.
Kavaii — She lives on your Mac. Not in the cloud.
Private, because there is nowhere else for it to go.
No account. No server. No telemetry. Everything you type, say or show her stays on your Mac, encrypted. Kavaii goes online exactly once — to download the character brain you pick. Turn off Wi-Fi in the middle of a conversation and she won't even notice.
Alive, not a chat window.
Nana stands in a 3D meadow and moves on her own — walking, looking around, gesturing, reacting. You don't pose her and you don't prompt her into it. Give her a name and a personality and leave her running while you work.
Free to use. Not free to try.
Chatting with her, the 3D world, her personality, files — all of that is free, forever, with no account and no time limit. It is not a trial and it does not run out. One single purchase adds her voice, her eyes and her ears. No subscription, nothing recurring.
It just runs. We checked first.
On first launch Kavaii looks at your Mac — chip, cores, memory — and tells you which character brain runs well on it. You pick one it recommends, tap once, and it downloads. Nothing to configure, no versions to compare, no wondering whether your machine is fast enough.
ALWAYS FREE — not a trial, no account, no time limit
• Text chat with her, in over 50 languages
• The full 3D character and meadow — she moves and reacts on her own
• Her personality, her name, day and night, dancing
• Files: share a folder and let her write and read documents
• The hardware check and every curated character brain
• A smaller conversation memory
PREMIUM FEATURES — added by a single one-time purchase
Everything above stays free. These are the Premium Features, shown but greyed until you unlock them. One purchase adds all of them, permanently:
• Her spoken voice, lip-synced to every word — seven voices we trained ourselves: German, English, Spanish, French, Italian, Portuguese, Russian
• Free Flight — hands-free live conversation; you speak, and your voice goes into the model as real audio, never as a transcript first
• The camera — she sees what you show her
• Audio files as input — voices, music, instruments, background; ask her to transcribe, translate or summarise
• Images as input, and pasting text or images into the chat
• The larger, selectable conversation memory
She stays who she is.
Nana is an adult character and behaves like one. Kavaii is made for conversation, not for adult content: her age is fixed in the app and cannot be talked around, and every reply passes a safety layer before you see or hear it. All of it runs on your Mac — nothing is sent anywhere to be checked. This is not an adult app and it does not become one.
Kavaii is a 3D anime simulation, made for entertainment. Rated 13+.
Payment is charged to your Apple Account at confirmation of purchase.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Kavaii is now a one-time purchase. One purchase unlocks the full version and it stays unlocked.
She can work with your files. Share a folder with her and ask her to write something down — notes, a list, a page. She saves it there, and you can point her back at it any time with @filename, long after that part of the conversation has scrolled away. Free, no purchase needed.
Talk to her without typing. Tap the microphone in the chat and just speak. Your words are recognised entirely on your Mac, on the Apple Neural Engine, and sent as a normal message. Nothing leaves your machine. (macOS 26 and newer.)
Better manners. She no longer comments on how you look unless you actually showed her something.
Plus a long list of smaller fixes: long documents are no longer cut short while she is still reading them, stopping a reply now always stops cleanly, and the app tells you when it is rebuilding its memory instead of just going quiet.
