Kokage is a 3D AI character you can talk with by voice or text. Speak or type, and your character answers with a natural voice, shifting expressions, and lively gestures. Choose how your character replies: run an AI model right on your device for free, offline chat, or use Kokage Cloud to start talking right away with no model download. You can switch anytime in Settings. "Kokage" (木陰) is Japanese for the shade beneath a tree — a quiet place to pause during a busy day. TALK OUT LOUD Speak into the microphone and your character listens, with speech recognition running right on your device. Replies are spoken aloud with lip sync using a built-in Japanese or English voice, or a cloud voice. Names, dates, and numbers are pronounced naturally. AS MANY CHARACTERS AS YOU LIKE Create as many characters as you like, each with their own conversation history, memories, voice, and 3D avatar. Start with the included character or bring your own VRM file (VRM 0.x or 1.0), and import or export character cards anytime. PERSONALITY, STYLE AND LANGUAGE Shape your character's role, tone, reply length, and how often they start a conversation on their own. Converse in Japanese, English, or Chinese (Simplified or Traditional), or let them match the language of your latest message. SHOW A PHOTO With a vision-capable model, snap a camera photo to talk about what you see. Switch to the rear camera and your character turns around to look with you. IT REMEMBERS — AND YOU STAY IN CONTROL Your character remembers helpful details you share, like preferences and plans. Undo a new memory on the spot, review, edit, or delete memories anytime, or turn memory off completely. You can also add shared notes that every character can draw on. EXPRESSIONS AND GESTURES Your character shifts posture naturally as they listen, think, and speak — nodding, shaking their head, bowing, or cheering along with the conversation. CHAT INVITATIONS AND APPLE HOME Turn on invitations to receive a daily greeting or a warm check-in after time away. You can also connect Apple Home (off by default) so your character can check on lights and other accessories or control them when you ask. FREE ON YOUR DEVICE Download a recommended model tailored to your device once, then chat offline whenever you like. Setup shows the exact download size upfront, and you can also add compatible public models from Hugging Face. KOKAGE CLOUD (OPTIONAL) • Cloud chat: start talking right away with no model download. • Cloud voices: design a voice from a description like "a calm, gentle voice," or clone your own voice (or one you have permission to use) in Japanese, English, or Chinese. • New looks: generate a 3D avatar (VRM) from a text description, a picture, or both. • Cloud Motion: live movement generated on the spot to match what your character is doing (on by default; can be turned off in Settings). Cloud voices, new looks, and Cloud Motion also work when replies run on your device. Kokage Cloud features use Leaf, available as in-app purchases. Leaf never expires, and unfinished requests are never charged. If Leaf runs out and an on-device model is installed, replies seamlessly continue on your device. No sign-up is required: an account is created automatically and can be deleted anytime in Settings. PRIVACY When replies run on your device, your conversation stays on your device. No ads, no analytics. When you use Kokage Cloud features, only the data needed for that feature — such as your messages and recent context, an attached photo, or an uploaded recording — is sent to Kokage Cloud and its AI providers. The app explains what is sent before you start. AI replies can be inaccurate or objectionable. You can report any reply directly inside the app. Privacy policy: https://kokage.moe/privacy/ Support: https://kokage.moe/support/
