Chief of Staff: You Sleep, It Works the Night Shift

Description and use

The "Chief of Staff" app automatically processes a user’s schedule and messages overnight, producing a morning brief with priorities, draft replies, and a decided postponed task, all while keeping data private.

Problem

Users need a privacy‑preserving, automated night‑shift assistant that can read their schedule and messages, draft replies, and decide on postponed tasks without exposing data to external servers.

Outcome

The app delivers a privacy‑preserving night‑shift brief, cutting morning prep time by ~25 minutes, with real‑world tests confirming accurate priorities, replies, and decision handling.

Workflow

• Paste tomorrow's schedule, unread messages, brain dump, and one postponed decision into the Night Desk.
• The model generates priorities, replies, and a decision in the Night Log using strict‑format prompts.
• Morning Brief presents top 3 priorities with reasons, up to 3 drafted replies with tone labels, and the decided postponed task.
• Users copy the brief as markdown, regenerate, or start a new night; data persists in localStorage.

Evidence

The app runs 100% in your browser on an open‑weight model. It never phones home. No API key, no server, no account.

The night shift has three stages: Night desk, Night log, Morning brief.

The brief came back with real flaws: priorities 1–2 were right but their reasons were mismatched, priority 3 was the landlord‑lease example again.

The math: manual morning triage … takes me 20–30 minutes on a busy morning. The brief is there when I open my eyes: ~2 minutes to skim + copy.
