How do I stop AI from rewriting everything when I ask for one change?
Fence the request in: name the single part you want changed and add a lock sentence telling the AI to keep everything else exactly as it is, worded literally. For example, ask it to change only the second sentence and leave the rest untouched. Repeat the lock verbatim each time.
How to do it
- Name the one part you want changedInstead of a broad ask, point to the exact piece to edit, such as the second sentence. This stops the AI from treating the whole thing as fair game.
- Add a lock sentence to protect the restFollow your request with an explicit instruction: keep everything else exactly as it is. This is the lock that fences the change in.
- Say the lock word for wordState the protective sentence literally in your prompt. The exact wording is what holds the rest of the text in place.
- Ask again with the fence in placeResend the request now that it is fenced. The weak line sharpens while everything you liked stays exactly where it was.
Questions that come up
What if it still changes something outside the part I named?
Repeat the lock sentence word for word and be more specific about the single part you want touched. If it keeps drifting, quote the exact text to change so there is no ambiguity about what stays and what moves.
Does this work for changes bigger than one sentence?
Yes. Name whatever unit you want changed, then add the same lock keeping everything else exactly as it is. The method is about fencing the edit, not the size, so it applies to a line, a paragraph, or a section.
Why does saying the lock word for word matter?
The exact phrasing is the instruction the AI acts on. A vague version invites interpretation and broader edits, while a literal keep everything else exactly as it is leaves no room to rewrite the parts you wanted preserved.
Full transcript
You ask AI to fix one line — it rewrites everything. One sentence stops that. Next time, fence it in: change only the second sentence, keep everything else exactly as it is. That last part is the lock — say it word for word. Now ask again — the weak line sharpens, and everything you liked stays exactly where it was.
