Where local AI fits best

Yemma is the assistant that's already with you. It works anywhere, keeps your stuff on your phone, and doesn't need an account or subscription to be useful.

Everyday use

The things you actually reach for AI for

Works without internet

Apple's built-in model works on-device when available. If you choose Gemma for image help or an older iPhone, its one-time download also runs offline.

Private

Private by design

No cloud relay, no account, no telemetry. Your conversations stay on your phone because there's nowhere else for them to go.

Setup

Start without the big download

No account or subscription. Eligible iPhones open straight into Apple-powered text chat; Gemma downloads only when you choose it.

Context

Real conversations

Ask follow-ups, change your mind, think out loud. It keeps up.

Open

Fully open source

The Yemma app and its optional Gemma integration are open source. Read the implementation on GitHub.

Always there. Always yours.

Free, no account required, and ready without a Yemma model download on eligible iPhones. See what local AI feels like.
