Pick a character — its own personality and voice, in chat and on calls.
Izuki runs on Google's free Gemini. Get a key (sign in → Create API key), copy it, and paste it here. It stays on this phone only.
Gemini is best here — it can search the web and talk out loud. You can also let another free service answer (Groq is the fastest). Any one key is enough to start.
Auto hears the language naturally. Pick Nigerian Pidgin or a language below if your phone keeps changing your words into English.
Your face has a real face rig: the mouth moves with Izuki's voice, the eyes blink and look around. It stays only on this phone.
Liquid glass stays the default. Clear water pulls apart and rejoins with sound. Star crystal has rotating depth; Tidal pearl has a nacre surface and fine wavefronts.
Silent demo — no mic, model calls or credits. Cloud WAV replies animate from their real waveform. System voices use a quiet fallback because their audio isn't available to measure.
Say "wake me up at 7" and Izuki gives you a button that puts it straight into your Clock. On iPhone that needs one small shortcut, made once:
|.Android needs nothing — the button opens your Clock with the time filled in. Either way there's also an "Add to calendar" button that always works.
iPhone: in Safari tap Share → Add to Home Screen. Android: Chrome menu ⋮ → Add to Home screen. It opens like an app.
Voice conversations, account connections, PC pairing and reminders — in your installed app.
Reminders use your phone's notification permissions, sound and vibration settings.
Siri Shortcuts can open a question in Izuki. iOS does not allow this app to tap through or read other apps. Connected accounts work through their supported integrations.
Tap Drive at the top (or say “drive mode”): Izuki becomes your co-pilot, hands-free. “Take me to…” starts Google Maps' turn-by-turn; “find gas near me”, “play music”, “text that I'm on my way” are done at once. It speaks up after two hours at the wheel and when your battery runs low. 🎉 Fun mode makes it a cheeky road-trip buddy.
Your speed comes from your phone's location, while Drive mode is on only — it isn't saved or sent anywhere.
Checking Android control…
Optional and visible: Android opens its own Accessibility settings. When enabled, Izuki can do the phone navigation you directly ask for: Home, Back, recent apps, notifications and Quick Settings. It never acts in the background by itself.
Optional: this makes “Hey Siri, Izuki, what's the weather” open it with your words. Do it slowly, once, and skip it if it's confusing:
Now say “Hey Siri, Izuki”, then what you want. (Optional: Settings → Accessibility → Touch → Back Tap to run it by tapping the back of your phone.)
Add your Composio key, then connect each app below. Gmail, Calendar, Drive and supported socials can work from this phone while your PC is off.
If Gmail is connected on your PC already, link your PC below and leave this key empty to use those connections. Adding a key here creates separate phone connections; signing in to Composio alone does not connect Gmail.
Some social services require a business or creator account. Availability and limits depend on that service and your Composio plan.
The key stays on this phone and only ever talks to Composio. Got a new key, or think this one leaked? Delete it at composio.dev, make a new one, and paste it here to swap it over.
With PC v1.0.66: try “make a 32 bar trap arrangement at 100 bpm in A minor on my PC”. The MIDI draft is checked and saved in your PC's Music folder for import into a saved copy of your project. Live DAW listening is not available yet.
Have Izuki on a Windows PC? In the PC app turn on Call Izuki from your phone and paste its link here. Then “play lofi on my PC” and anything else on the PC work from here too.
If you haven’t added a Composio key above, your accounts still work through this PC link — it holds the apps Izuki is allowed into. Either way, if an app isn’t linked yet you’ll get a Connect button to sign in. Free: your own free key, nothing hosted.
Copy your PC's setup to this phone in one go — your AI keys, your connected apps (Gmail and the rest), your character, language and what Izuki remembers. Then this phone works on its own, even when the PC is off.
Tell us what happened. Izuki puts together a report with the details needed to fix it (never your keys or chats) for Izuki's maker.
You can also just say “clear chat” — or type it — any time. Same as the PC app.

Free and private: your key, chats, memories and reminders are kept on this phone. Messages go straight to the AI you picked (Google's Gemini unless you chose another) and to your own PC if linked. Error reports carry what went wrong — never keys, chats or recordings.
