hYYa ai

Two engines. Offline or Online — you're in control. hYYa Cloud runs frontier AI models; hYYa Vault runs on your device — no data sent anywhere. One app. Both engines. Everyone else makes you pick a side — a cloud service, or a local model runner. hYYa runs hYYa Vault on your own device and hYYa Cloud on the world's most powerful models, with one memory across both. You switch engines, not apps. Every other assistant makes you pick a side: a cloud service, or a local model runner. hYYa is one app with both engines — and one memory across them. Switch engines, not apps. It's your data, your memories, and your choice.
