Tobias

A private personal assistant, built and used by one person.

Tobias runs on its owner's own computer. It brings together their calendar, personal finances, health readings and smart-home devices in one dashboard, and can read a short morning briefing aloud on a home speaker.

Tobias is not a public service. There is no sign-up, and it is not offered to anyone other than its owner. The Google sign-in screen that mentions Tobias exists only so the owner can connect their own Google account.
