In simple terms

• The mark is invisible. It is a hidden pattern in the words, or hidden information inside the picture file.

• The rule is European, but companies do not want to build two versions of the same product. So European rules quietly become world rules.

• Older systems have until December to catch up.

• The mark is a hint, not proof. Editing or translating can rub it off, and lots of AI content has no mark at all.

What it means for you

You will start seeing "made with AI" labels on adverts, photos and support chats. That is good.

But do not flip it around. No label does not mean a human made it.

3. Very big money is betting on AI

What happened

Nvidia makes the chips that nearly all AI runs on. It is now in talks to buy a piece of Perplexity, an AI search engine. The price being discussed values Perplexity at more than $30 billion. Perplexity sells about $750 million a year.

At the same time, SoftBank is borrowing a record amount from ordinary Japanese savers, partly to pay back a loan tied to OpenAI.

In simple terms

• Watch the circle. The chip seller invests in a customer, and the customer spends the money on chips. That can make demand look bigger than it really is.

• The price is steep. Perplexity would be worth about 40 times what it sells in a year. A normal solid company is worth 3 to 8 times.

• Everyday savers are now helping to pay for it.

What it means for you

You do not need to own AI shares to be affected. If you have a pension or an index fund, you already own a slice of Nvidia, Microsoft and Google.

If the bet works, that helps you quietly. If it is a bubble, it hurts you the same quiet way. This is not advice — just a map of where your money already sits.

Quick hits

• Google changed the engine behind its answers in Search. Paying subscribers first. If Google feels different lately, that is why. (Search Engine Land)

• AI agents are getting their own logins at work. An agent is a bot that does tasks for you. Until now they borrowed a human's password. That was a bad idea.

• If your AI agent buys the wrong thing, who pays? Google and US lawmakers are both working on an answer. Nobody has one yet.

• Intel's big new chip slipped to 2027. Nvidia still has no real rival.

One prompt worth stealing

Next time an AI gives you an answer you cannot check, try this:

Why it works: the last part forces the AI to point at its own weak spots instead of sounding confident. It is the closest thing to a free fact-check.

That is it for today.
