The AI Daily Brief Prompt That Tells You What Matters, Not Everything

Most people who try an AI daily brief prompt get the same result: a neat summary of their own calendar. Nine o'clock, this. Eleven, that. Two meetings in the afternoon. It is accurate and completely useless, because you can already see your own calendar. What you actually want is the thing a good chief of staff gives you before you walk into the day: the one thing that matters, what has changed, what is about to go wrong and what you can safely ignore.

I spent years running CEO offices, and the job was never to list everything. It was to decide what could be left out. Below is the prompt I'd give anyone starting out, then what each part does, how to feed it, schedule it and sharpen it over a week.

01 / The AI daily brief prompt (copy this)

This works in ChatGPT and Claude. Paste it into a project if you use one, so it sits alongside anything the AI already knows about you, and fill in the square brackets the first time.

You are my chief of staff. Using what you know about my role and everything I give you today, write my brief for today.

About me (skip anything already in your project instructions):
- My role: [one line]
- What I would be judged on if the month ended tomorrow: [two or three priorities]
- What "at risk" means in my world: [e.g. a slipping deadline, a person going quiet, a decision with no owner]
- Who cannot be left waiting: [names or roles]
- Fixed commitments outside work: [school run, appointments, anything that always gets left out of planning]. Treat these as fixed, not as preferences.

Today's inputs:
- Calendar: [connected, or screenshot attached]
- Waiting on: [who owes me what]
- On my mind: [anything quietly worrying me about the week]

Run it once now, then read on.

02 / What each part is doing

"You are my chief of staff." This sets the job. Without it, the AI defaults to helpful summariser, which is exactly what you are trying to avoid.

About me. The most important line is what you would be judged on. Until you say out loud what you consider important, everything looks equally important to the AI. Ninety seconds describing a good month does more than any clever wording elsewhere.

THE ONE THING. One item, not three. This is the line that forces a decision. If you let it give you a top three, you get a slightly shorter to-do list.

TODAY. The only section that touches your diary directly, and it is there to flag preparation, not to recite times. "Thursday's leadership meeting needs the supplier recommendation and the only clear block before it is Tuesday morning" is a brief. "Leadership meeting, Thursday, 10am" is a calendar.

CHANGED. Meetings that shifted, new invitations, something quietly declined. This is what makes the brief worth reading daily.

AT RISK. The part nobody else is watching. In most jobs, a person going quiet is the earliest warning sign you get.

DROP. People underestimate this one. A brief that lists everything is just your calendar with extra steps. A brief earns its place by leaving things out.

The rules. "No summarising my calendar back to me" kills the most common failure. "If nothing belongs in a section, leave it out" stops it padding. And "assume I am reading this standing up" does more than it looks like it does: it forces density.

03 / Feeding it your calendar, email and notes

The brief is only as good as what it can see. You need three things: your calendar for the next seven days, your current priorities, and a rough list of what other people owe you. That is enough. Do not try to feed it your whole inbox on day one.

If you can connect your calendar, do. This is where connecting genuinely changes the output rather than just saving you a step, because a connected calendar can show what moved, and a screenshot cannot. In Claude, the Google Calendar and Gmail connectors are switched on from the plus menu in a chat, under Connectors (on Team and Enterprise plans an admin has to enable them first). In ChatGPT, connected services are called plugins and live under Settings, then Plugins; Gmail and Google Calendar are both there, including in the UK, though what you see can depend on your plan and workspace. Once it is connected, "brief me for today" is enough.

If you cannot connect it, screenshot it. Plenty of organisations will not allow the connection. Screenshot your week on your phone and drop the image in. Both tools read it fine. Do not retype your diary, do not export anything and do not tidy it up first.

Everything else goes in by voice. Your priorities, what you are waiting on, what is worrying you. Once you have done it a few times, the whole input step is a screenshot and a voice note, under two minutes.

If your day is not run by a calendar, a screenshot of it tells the AI almost nothing. Give it your ticket queue, your shared inbox or your task list instead, and change THE ONE THING line to "the one thing most likely to become a problem if nobody touches it today".

04 / Write your attention rules

The "About me" block gets you started. Your attention rules are what make the brief stay good. Answer these out loud, once, and save the answers in your project instructions so you never have to say them again:

• What makes a day good for you? Not what should. What does.

• What do you always regret missing?

• What do you over-attend to, the thing you will happily spend an hour on because it feels productive and is not?

• Who cannot be left waiting, and who can?

• What does "at risk" actually mean in your world?

The AI does not know that Thursday's meeting is the one where the decision actually gets made, or that the supplier who has gone quiet has done it twice before and it ended badly both times. Your rules tell it.

In AI Powered Chief of Staff, these rules become one section of a single Chief of Staff Brief that lives inside your AI as project instructions, so the daily brief, your meeting prep and your weekly review all work from the same picture of you.

05 / Schedule it so it is waiting for you

A daily brief you run four days out of five is not a daily brief. It is a habit you are losing. Both tools can now run a prompt on a schedule, though the details change often, so treat this as accurate as of October 2026.

In ChatGPT, scheduled tasks are available to eligible users on Free, Go, Plus, Pro, Business, Enterprise and Edu plans. You can set one up from the Scheduled page or simply ask in a chat, for example: "Run my morning brief at 7.30 every weekday." Results can reach you as a push notification, an email or both, set under Settings, then Notifications. Two things to know: the number of active tasks you can have depends on your plan, and a task created inside a project cannot read the files uploaded to that project. If your brief relies on a saved file, put that information in your instructions or in a connected app instead.

In Claude, scheduled tasks are available on paid plans (Pro, Max, Team and Enterprise). Open Scheduled in the left sidebar and choose New task, or type /schedule in a task and let Claude set it up with you. You can choose daily or weekdays, and tasks can use your connectors. They run even when your computer is asleep or the app is closed.

Whichever you use, add one line to the scheduled version, because a scheduled brief cannot ask you a follow-up question:

And pick a time you will actually read it.

06 / Improve it over a week

Day one's brief will be fine. The point of the first week is to make it sharp, and the fix is almost never the prompt wording.

Day one: ask what it left out. Straight after the first brief, send this:

Usually this shows that one of your attention rules is vaguer than you thought. Fix the rule, not the prompt.

Days two to four: run it before you look at your calendar. Then check three things. Did it surprise you? If it only told you what you already knew, it is summarising rather than briefing, and usually it cannot see enough. At the end of the day, was THE ONE THING right? If not, that is your rules, not the tool. And did you act on DROP? If you did everything anyway, either the suggestions were weak or you do not trust it yet.

Day five: vary it by day. Monday needs a week-ahead view. Friday needs a what-did-not-happen view. Wednesday just needs today. Add a line telling it so.

End of the week: let it grade itself.

Keep each day in its own conversation. Yesterday's context clutters today's brief.

A good brief takes under a minute to read and changes at least one decision. If it changes nothing three days running, the problem is upstream, in what you have taught it to care about.
