The one thing AI does better than any human

Last issue I wrote about why AI projects fail. This week, I want to flip the question: where does AI actually work brilliantly?

Not where it looks most impressive in a demo. Not where a vendor tells you it will save 40% of everything by Christmas. Where it actually changes the work.

My answer: synthesis.

By synthesis, I mean the awkward middle layer between raw information and a decision.

Every organisation has too much information. Board papers, meeting notes, supplier updates, customer feedback, policies, spreadsheets, competitor activity, inboxes, PDFs, Teams chats, project documents. The problem is rarely that the information doesn't exist. The problem is that no one has the time, context, or patience to pull it together properly.

So decisions get made from partial views.

The board pack summarises what was easiest to summarise. The project update reports what the project manager remembered to include. The supplier review focuses on the last thing that went wrong. The customer insight deck quotes the loudest feedback, not necessarily the most representative.

That gap — between everything the organisation knows and what the decision-maker actually sees — is where AI is genuinely powerful.

A good language model can read ten documents, compare them, spot contradictions, pull out recurring themes, and turn the mess into a clear view of what matters. It can do the boring first pass of understanding at a speed no human team can match.

That's not because AI is wiser than people. It isn't. It has no judgement of its own worth trusting blindly.

But it is very good at collapsing the distance between scattered information and a usable briefing.

The human still makes the call. The AI gives them a better starting point.

That is a much more interesting use case than “write me a nicer email”.

Here are three places this shows up immediately.

1. Competitive intelligence

Most companies know they should track competitors. Few do it consistently. Someone looks before a strategy meeting, a few screenshots get pasted into a deck, and everyone moves on.

AI changes the economics. It can monitor public updates, product pages, pricing signals, job ads, press releases, reviews, and social posts — then summarise what changed and why it might matter.

The value isn't “a list of links”. The value is: what is the pattern?

Are they hiring in a new capability? Changing positioning? Discounting aggressively? Moving into a category we care about? Saying something different to customers than they said six months ago?

That's synthesis.

2. Board and leadership packs

Board packs are full of information. The hard part is not producing pages. The hard part is knowing what the pages are saying when viewed together.

AI can take sales commentary, risk logs, financial notes, project updates, and customer signals, then produce the questions a good non-exec would ask.

Where are the numbers and the narrative drifting apart? Which risk has been mentioned three months running without a decision? Which metric looks fine in isolation but worrying in context?

Again: the AI is not replacing governance. It is making governance harder to bluff.

3. Cross-document analysis

This is the one most people underestimate.

Organisations constantly need to compare documents: contracts against policy, supplier promises against actual performance, customer complaints against process notes, project plans against status reports.

Humans can do this. Humans are also busy, interrupted, and expensive. So the comparison often doesn't happen until something goes wrong.

AI makes the first pass cheap enough to do routinely.

“Read these five documents. Tell me where they contradict each other. Tell me what changed. Tell me what I should ask before approving this.”

That single pattern is useful almost everywhere.

The mistake is treating AI as a junior copywriter. Useful, yes. But small.

The bigger opportunity is treating it as a synthesis layer across the information your organisation already has.

Not the decision-maker.

The thing that makes the decision-maker harder to fool.

This is where Microsoft Copilot starts to make more sense.

Most organisations bought Copilot expecting a productivity layer: faster emails, meeting summaries, cleaner PowerPoint drafts. Useful, but not transformational. The more interesting use case is grounded synthesis across work that already lives inside Microsoft 365.

Take a board pack, a project update, a risk register, and a few meeting notes. The obvious prompt is: “summarise these”. Fine. But the better prompts are sharper:

That's where Copilot becomes more than a writing assistant.

The catch is that it only works well if your underlying documents are accessible, named sensibly, and contain enough context. AI does not magically fix poor information hygiene. It exposes it.

But used properly, this is one of the most practical starting points for corporate AI: not asking Copilot to sound clever, but asking it to make the organisation's own information easier to interrogate.

Verdict: Underwhelming as a generic writing assistant. Much more useful as a synthesis layer over documents, meetings, and management information — if your Microsoft 365 estate is in decent shape.

This is also the idea behind one of my recent YouTube videos: using one AI system to help another produce better work.

What Happens When Your Two AIs Talk to Each Other

The point isn't the novelty of two tools interacting. The point is that one system can carry context, extract patterns, and improve the quality of another system's output.

That's synthesis in practice.

1. The best AI prompts often start with “compare”, not “create”. Compare these documents. Compare this plan with last month's version. Compare this supplier claim with the contract. Creation gets attention. Comparison creates value.

2. If your organisation has Microsoft Copilot but no agreed examples of high-value use cases, start with document synthesis. It is safer, easier to understand, and closer to daily management work than most automation ideas.

3. “AI hallucination” is a real risk, but it is also sometimes used as an excuse to avoid changing the process. The right control is not “never use AI”. It is source-grounded workflows, human review, and clear rules about what the AI is allowed to conclude.

“If AI still needs checking, doesn't that cancel out the time saving?”
— Finance leader

No. It changes where the time goes.

You should absolutely check AI output. But checking a structured first draft is different from creating the first draft from scratch.

If AI reads eight documents and gives you a one-page briefing with source references, your job becomes verification and judgement. Are the quotes accurate? Has it missed anything material? Do the conclusions follow from the evidence?

That's still work. But it's higher-value work.

The trap is expecting AI to remove the human. The better model is using AI to move the human further up the value chain — away from trawling through material and towards deciding what it means.

This is the AI use case I think most leadership teams should understand first.

Not because it is flashy. Because it is immediately useful, relatively low-risk, and close to work they already recognise.

Next week I'm going deeper on Microsoft Copilot — the tool many of you already have access to, and the one most organisations are still barely using properly.

See you Tuesday.
