Wake up to your day, done.

zerohrs is an AI assistant that reads your calendar, inbox, and meeting notes overnight and gives you a 12-minute morning briefing instead of the 78-minute catch-up most knowledge workers do today.

Why we're building this

Mornings are where the leverage is. The first hour of a knowledge worker's day sets the trajectory for the next eight, and most of that hour is spent re-loading context that already existed yesterday. We're building zerohrs because we got tired of doing that to ourselves.

The product is calendar-first, not inbox-first. We start from what's on your day and work backward — surfacing the threads, docs, and decisions that matter for the conversations you're actually about to have.

Our take on privacy

zerohrs touches your most sensitive data — inboxes, calendars, meeting transcripts. We treat that as a privilege, not an entitlement. Briefings are generated server-side, never stored longer than they need to be, and we never train foundation models on your data. Details live in our privacy policy.

We're a small, founder-led team shipping in public. If you want to follow along, we're @zerohrs on X. If you want early access, join the waitlist.
