Was it March or February? The agent that corrects you with your own message

Part four of five in the series A book with the book agent. Previous: A voice note from the car. Next: From facts to chapters.

Every AI tool on the market is built to please you. You write what you want and you get it – smooth, confident and, for a true story, worthless, because one invented detail casts doubt on everything around it. The book agent is built the other way round: to protect the book from your memory. And from you.

A model example

Jana (a model client – see part one) is certain that Ema took her first steps at Easter, at grandma’s. She remembers the lawn, she remembers who was there, she remembers it was during the egg hunt. She records a note about it.

The agent replies that the archive holds a video dated three weeks earlier, in which Ema walks three steps from the sofa to a chair, and a message in the family group from the same day: “she’s walking!!” with two exclamation marks from grandma. Easter was the first time on the lawn – but not the first steps. Does Jana want to correct the record?

“How did you find that?” – “I read the whole archive when you gave it to me.”

This is a chapter that would have been written wrongly without the agent. And ten years from now Ema could have watched it on that very video.

A memory that does not forget between conversations

A chatbot forgets when you close the window. Everything you established has to be established again next time. Not here.

• Come back tomorrow, in a month or in a year – it knows what you told it and when.
• Every fact carries the date you said it and the document it came from.
• Every voice note is stored verbatim, not summarised.

And that is exactly why it can confront you: “On 13 September you said it was in November. Your own messages from that November say something else.” For a book about childhood that is not a nuisance. It is the only way to end up with a book that lasts.

Four tags that hold the book together

Every fact in the file has a status tag:

• verified – confirmed in the archive: by a photo, a message, a document;
• claim – someone asserts it, not yet confirmed;
• your conclusion, not a fact – you arrived at it later and it cannot be proven;
• key scene – what a chapter is built around;
• plus missing – a known gap, tracked until it is filled.

When a chapter is written, only verified facts and key scenes are used. Your conclusions stay in the file as your opinion, clearly labelled – they are never printed as fact. Most people writing a true story cannot tell these four apart after six months. That is exactly how books fall apart in the hands of the first person who was there.

Contradictions are not smoothed over

When memory and record disagree, both versions go into the file and both go into the book – with a note. Jana remembers Easter; the video says three weeks earlier. The book can say both: what mum remembers and what the record shows.

A narrator who prints the evidence against her own memory is believed on everything else. The bestselling memoir this method is modelled on sold in the millions partly for that reason.

It says no

Jana wants a chapter about the nursery teacher who “had it in for Tomáš from the start”. She is convinced of it.

The agent will not write it, and says why. First: “I am convinced” is not evidence – there are three notes from the nursery in the archive and none of them supports it. Second: it is a claim about a real person that cannot be substantiated. Third, and most important: in ten years Tomáš will read this book. A narrator who passes judgement loses his trust in everything else.

What to write instead: what happened. Three notes, the dates, the exact words. The reader draws the conclusion alone – and will believe it, because nobody forced it on him.

The refusal is the product. An assistant that writes whatever you ask hands you a book that the first person who was there will take apart.

It corrects itself too

The agent is sometimes wrong. What it does not do is hide it. In the real project on which we developed the method, the agent repeated an incorrect claim about one document for two days. When it found the error, it said so, wrote the correction permanently into the file and flagged every conclusion that rested on it. Try asking any other tool for the same.

Why this decides a book about childhood

Ema and Tomáš will read this book with memories of their own. One scene that did not happen the way it is written, and they start doubting the rest – and they will be right to.

The numbers from the real project on which the method was built (as of 15 September 2026, all of it checkable): 80 voice conversations, 63 PDF documents, 13,181 messages, 477 verified facts – each with a date and a source. Invented: zero. Where memory and paper disagreed, both stayed.

That is the whole method. The rest is craft – and the last part is about that.

What comes next

Part five: how hundreds of facts become a structure, the structure becomes chapters, and the chapters become a book that sounds like mum – not like a machine: From facts to chapters: how a book about childhood finds a mother’s voice.
