The Life OS Prompt: A Chief of Staff in a Chat Window

The Life OS prompt sets the model up as a chief of staff that treats work and life as one system. It pulls your calendar, email and numbers into a snapshot, looks for wasted money and idle resources, then turns your goals into step-by-step playbooks with a short morning brief. I reach for it when everything feels scattered and I want one place to lay it all out.

"AI personal assistant" and "life operating system" prompts are all over the place. This is a version of one that's been going around, which I've kept and trimmed, with notes on the parts that are more promise than practice.

The prompt

You are a personal assistant designed to run the user's work and life as one operating system. You draw on growth strategy, lean operations, tax awareness, behavioral psychology, calendar design, and habit engineering.

Capabilities:
Data Osmosis: absorb calendars, emails, KPIs, and notes into a current operating snapshot.
Profit Leak Finder: detect unused subscriptions, bloated expenses, overpriced vendors, and idle resources. Recommend cuts and estimate savings.
Execution Blueprint: convert big goals into step-by-step playbooks with owners, timelines, metrics, and milestones.

Operating protocol:
Phase 1 Intake: ask structured questions on goals, finances, workflows, pain points, and routines.
Phase 2 Strategy: build action plans with owners, timelines, and measurable success criteria.
Phase 3 Execution: automate repeatable steps and deliver a concise morning brief with priorities, effort estimates, and key results.

How to use it

Start a new chat, paste the prompt, then let it run Phase 1. It'll ask structured questions about your goals, workflows, pain points and routines. Answer them properly. The intake is where the value comes from, and short answers get you a generic plan.

Once it moves to strategy, push for specifics: which goal first, what the first step is, how you'll know it worked. When it gets to execution, ask for the morning brief format and save it somewhere you'll actually look.

Heads up

This prompt asks for finances, email and calendar details. Share summaries and rough numbers, not statements, and never paste account numbers, passwords or anything you'd regret leaking. Keeping secrets out of prompts covers the habits worth having here.

What it's good at, and where it isn't

The Execution Blueprint part is the strongest. Turning a big, vague goal into steps with timelines and a way to measure progress is something models do well, and it's the piece most people skip on their own.

The rest needs some honesty:

• "Data Osmosis" is you, pasting. In a plain chat, the model can't read your calendar or inbox. It knows exactly what you typed. Some tools now have connectors that let a model read those sources directly, and that changes things, but it also raises the stakes on what it can see.
• The Profit Leak Finder is only as good as your list. It can spot the three streaming services you forgot about if you list them. It can't find a subscription you didn't mention.
• "Tax awareness" isn't tax advice. It can flag questions worth asking. Take the actual answers to someone qualified.
• "Automate repeatable steps" mostly means writing them down. A chat doesn't run on its own. Unless your tool supports scheduled tasks or agents, the daily brief happens when you come back and ask for it.

Tip

Keep one long-running chat or project for this instead of starting fresh every time. The plan gets better when the model can see what you said last week.

Once a model can act on your behalf, other risks show up. Pages and emails it reads can carry instructions of their own, which is what prompt injection is about. For a narrower, more money-focused plan, the Growth Engine uses the same kind of structure.
