Five hours. That is half a day. A strategic lunch, a one-on-one with someone who reports to you, an hour of thinking you never seem to get. And it is not wishful thinking. BCG measured in 2025 that 58% of regular generative AI users save more than five hours a week, and 47% save more than an hour a day. These are the executives I work with. Not by reinventing their company. By changing five habits.
Because the executive problem is not that you do not work enough. It is that you work on the wrong things. Emails, notes, summaries, formatting. The tasks that eat the thinking and deciding time you are actually paid for. And most leaders are still nowhere near using AI on those recurring tasks, so the time sitting on the table is enormous.
Email: 45 minutes back every day
An executive receives somewhere between 80 and 150 emails a day. Not spam, real emails that need an answer. Most of them do not need your deep thinking. They need your decision, and a clear reply.
Here is how I do it with the leaders I train. You read the email. You dictate your answer in three sentences, even messy ones. AI rewrites it in a professional tone, adjusts the length, and hands you a clean version. You approve it or change a word. Sent.
An email that used to take 8 minutes now takes 2. Across 20 emails a day, you get almost an hour back. And your replies get clearer, because you drop the reflex of burying the message under caveats.
Briefs and notes: 30 minutes per document
You have to write a note for the board. A brief for an agency. A framing document for a project. You know what you want to say, but the blank page costs you time. Not because you cannot write, but because you are hunting for the structure.
Give AI your raw ideas, your key points, your constraints. Ask for a first structure. You read it back, you adjust, you fill the gaps. In ten minutes you have a solid document that would have taken 45 minutes to write from scratch.
One managing director I work with now prepares his framing notes by dictating in the car. By the time he reaches the office, the document is waiting, structured and clean. He fixes two sentences and sends it. He used to block an hour in his calendar for that.
Meeting prep: 20 minutes instead of an hour
How many meetings do you walk into underprepared because you ran out of time? It is the classic move of the overloaded executive. You show up, you wing it, you improvise. Sometimes it lands. Often you leave thinking you could have done better.
With AI, you load the meeting documents, the agenda, the previous minutes. You ask for a summary of the key points, the open decisions, the hot topics. In ten minutes you have the full picture. You arrive prepared. And the meeting moves faster because you move faster.
Something I recommend often: ask AI to prepare the three questions you should be asking. Not to read them out, but to switch on your thinking beforehand. It completely changes the quality of your contributions.
Summaries: from two hours to twenty minutes
An 80-page report lands on your desk. A competitor benchmark. A market study. An internal audit. You know you should read it. You know you will not, or you will skim it diagonally.
Load the document into AI. Ask for a one-page summary with the five key points. Then ask your own questions: what risks is the author underestimating? What contradicts our current strategy? What data is missing?
You are not replacing the reading. You are making it possible. You pull the essentials in twenty minutes, and you keep the right to dive into the detail if a point deserves it. It is the opposite of skimming: you read with precision, just faster.
Reporting: automate the gathering, keep the analysis
Friday afternoon, you compile your numbers. You open four files, you copy data across, you update a table. It is mechanical work. And it is exactly the kind of task where your time gets wasted.
AI will not replace your judgement on the numbers. But it can produce the comparison table in five minutes instead of forty-five. It can flag the anomalies, the trends, the gaps against plan. You focus on what it means and what to decide.
A CFO I train cut her weekly reporting from two hours to thirty minutes. Not by cutting corners, but because gathering and formatting no longer cost her anything. She spends her time on the analysis, where she actually adds value.
The trap to avoid
I always warn the leaders I work with. The risk is not using AI too much. It is using it on everything, including what needs your slow thinking. A hard negotiation, a sensitive piece of feedback, a restructuring call. Those need your brain, not a shortcut.
AI is there to free up time. Invest that time in what nobody can do in your place. The hard conversations, the vision, the strategic calls. If you spend the five hours you saved writing more emails, you missed the point.
How to start this week
Do not change everything at once. Pick one single task from the list. The one that annoys you most. The one where you lose time every week. Try it for five days. Measure the time you save. Then add the next one.
Within a month you will have your five hours back. And you will wonder how you ever managed without it.
Frequently asked questions
Which executive tasks can you hand to AI?
The most profitable ones: handling email, writing briefs and notes, preparing meetings, summarising long documents, and reporting. These are high time-value, repetitive tasks, and exactly where AI excels.
How much time can AI actually save you?
Between 4 and 8 hours a week for an executive who uses it on recurring tasks. The gain depends on your volume of email, meetings and documents. The first results show up within the first week.
Can AI write my professional emails?
It writes the first draft. You fix the tone, adjust the message, and decide what goes out. An email that takes 15 minutes now takes 3. Times 20 emails a day, the math adds up fast.
Which tool should you start with?
A conversational assistant like Claude or ChatGPT is enough to begin. You do not need a complex tool. Give it context, ask for a result, correct it. What matters is building it into your routine, not piling up tools.
The ramp is simple: one task this week, the next one the week after. In a month of small changes, you have recovered a full half-day, every single week.
