Why AI makes things up, and what stops it

It is not you. It is the way your material went in.

1 Hour AI

Turn AI into your personal assistant in less than 1 hour. No technical skills required. It arrives already built, so you just need to switch it on.

PRICES EMAIL NOTES PHOTOS ? Four different things in. One blur out.

You have seen it happen. The first answer was fine, so you kept asking.

An hour into the chat, the answers got worse. It forgot things you had already told it. In the end it told you something confident and wrong. That was not you. That was the way your material went in.

People call it a hallucination

There is a word for this and it explains nothing. People call it a hallucination. That makes it sound like a fault in the machine. It is not a fault.

The machine is doing exactly what it was built to do. It is filling a gap with something shaped like an answer. Once you see why the gap is there, you can close it.

Picture a blender

AI does not read your document the way you do. It takes the whole thing in as one lump. Tip a whole fruit bowl into a blender. You get one brown drink.

Now find the strawberry. You cannot. It is in there, but not as a strawberry. That is your document once it goes in.

Ask about one exact line and there is no line any more. There is only the blend.

The more you add, the worse it gets

Now add a second file. Then a third. The more you pile in, the less of each piece it holds. So it works from the general gist, not your exact line.

Detail is the first thing to go. This is why a long chat gets worse the longer it runs. Nothing broke. The pile just got deeper.

Two reasons it starts guessing

Sometimes it cannot find the answer in the blend. Sometimes it never understood the question. Either way it starts guessing. It invents something that might fit.

The answer sounds sure. It is wrong. And it never sounds any different from a true one. That last part is what costs people money.

You did nothing wrong

This is why the AI project at your company went nowhere. It is why the tool you tried in January is not open now. Nothing was wrong with you and nothing was wrong with the AI. Your material went in as one lump.

A better question would not have saved it. You cannot ask back a detail that was already blended away.

The fix is one idea, one note

So stop handing it a lump. Whatever you give it is kept exactly as it arrived. A file, an email, a page of notes. Untouched. Then a copy is taken apart, thought by thought.

Every separate thought becomes its own small note. One idea. One note. A note about your prices is only about your prices. Nothing else is blended into it.

So when you ask about prices, it lands on that note exactly. Every thought you handed over has a home now. There is nothing left for it to guess at.

Then the notes are joined to each other

The price note knows about the supplier note. The supplier note knows about the job you did in March. Ask one question and the connected ones arrive with the answer. That is the part a plain chat window cannot do for you.

PRICES What you charge the date on it where it came from SUPPLIER Who you buy from the date on it where it came from MARCH JOB What it really cost the date on it where it came from One idea. One note. And you can always ask where it got that.

Ask it where it got that

Every note also carries where it came from. So you can always ask it where it got that. If it cannot point at a note, it invented it. That is your check, and it takes three seconds.

And when two notes disagree

Every note carries a date as well. So when two notes disagree, it shows you both. It does not quietly pick one and hope you do not notice. You decide which one is still true.

The three things that made it click

I watched videos about AI for more than a thousand hours. I started. I stopped. I started again. Nothing stuck. Then three things happened, and it clicked.

  1. One

    Skills

    You do not ask AI to do a job. You teach it one.

    You hand over the instructions once. It reaches for them every time that job comes up.

  2. Two

    Why it makes things up

    Your material goes in as one lump, so the detail is lost.

    When it cannot find the answer, it fills the gap with something shaped like one.

  3. Three

    The fix

    One idea, one note, and every note carries its source and its date.

    Your AI reads those notes before it answers, so it has nothing left to guess at.

Those three are why I built 1 Hour AI.

The whole idea, in two lines

One big pile, confident guessing. Small sharp notes, exact answer. You now understand this better than most people who talk about AI for a living.

Questions people ask about this

Is my AI broken?

No. Nothing is wrong with it. Your material went in as one lump, so the detail was lost before you asked.

Would a better question fix it?

No. A question cannot bring back a detail that was already blended away.

Is this only about long documents?

No. A long chat does the same thing. Every answer piles on top of the last one.

Do I have to write code?

No. You switch it on with your mouse. Nothing in it is technical.

What happens when it does not know?

It can point at the note it used, or show you that there is no note. That is the check.

You can stop it guessing today.

The second brain is the notes, in an order your AI reads before it answers. It is free, and it takes about an hour to switch on.
