ThinkByte: Offline Local AI

New: talk to it. Ask by voice, type, or share a photo and get answers right on your iPhone. No internet, no account, and your conversations never leave the device.

ThinkByte is an AI assistant that runs on your iPhone instead of in the cloud.

Ask it a question, talk to it, or show it a photo, and it answers right on the device. Nothing connects to a server, so it works the same on a flight, on the subway, or anywhere with no signal. Your conversations stay on your phone and are never uploaded.

Type or talk. Use the keyboard, or hold the mic and speak. ThinkByte takes voice and images, not just text.

Choose your model. Download a small, fast model or a larger one for tougher questions, right from the app. More get added over time.

Private by default. No account. No sign-up. Your chats never leave your phone. Anonymous diagnostics are optional and you can turn them off in Settings.

Built for real life: Flights and travel Subways, basements, and dead zones Limited or expensive data plans Anyone who would rather keep their conversations off other people's servers
