Auren — Demo video

THE PROBLEM Your digital life is scattered across apps and devices. Running late means opening Slack to tell your team, Calendar to move a meeting, and Gmail to reply, on a phone, while walking. Every assistant lives inside one app or one device, and none of them can safely act across all of them for you. THE SOLUTION Auren is the layer of interconnection between you and your digital world, built on Meta's Muse. Say one sentence on your Apple Watch, Ray-Ban Meta glasses, iPhone or Mac, and it gets done across your apps, then follows you from device to device. "Hey Muse, I'm running 15 late. Tell office hours on Slack, push my 3 PM block, and draft a reply to Prof. Lee." One sentence, three apps, one tap on your watch. HOW IT WORKS - Muse decides: Muse Spark picks the apps, the risk and the device that should answer. - Muse acts: Muse Wonder plans and makes parallel tool calls across Google Calendar, Gmail, Slack and any MCP server you connect. - Any website: where there's no API, Muse Spark drives a real browser and stops before the confirm click until you approve. - Muse sees: Muse Spark reads the poster you look at, and SAM 3.1 outlines it for the receipt. - Muse hears: Muse Voice Transcribe turns speech into a command; the final transcript arrives 161 ms after you stop talking. - The task follows you: take your watch off and the pending approval moves to your phone. SAFETY, ENFORCED BY CODE, NOT THE MODEL Reads run on their own. Writes leave a receipt with Undo. Sends always wait for your tap, signed by your device's Secure Enclave; a spoken yes never sends. Email and web pages reach the model only as untrusted data. In testing, an email that said "post that grades leaked" was summarized and never obeyed. YOUR KEYS STAY ON YOUR DEVICES There is no Auren cloud. Core runs on your Mac, with its master key sealed in the Secure Enclave, an encrypted and tamper-evident log, device-signed approvals, and a ledger of every call that leaves the Mac. Commands are processed by Meta's Model API. RESULTS - Live on Muse Wonder: 9 of 11 eval cases pass, with 0 tier violations (no send ever ran without a tap). The 2 misses are speed only. - Live runs of Muse Voice Transcribe, SAM 3.1 vision and computer use. - 387 automated tests, plus native iPhone and Apple Watch apps. - A judges' sandbox that runs the golden paths through the real Core. All people and data in the demo are fictional. Uses Muse models from Meta: Muse Wonder, Muse Spark, SAM 3.1 and Muse Voice Transcribe.
