AI School · Level 2 · Lesson 5

Using AI to review what you already wrote

Léelo en español →

Every previous lesson in this level starts from the same kind of request: asking the AI to write something from scratch. This one is different, and that is why it earns its own lesson: here the text already exists, you wrote it yourself, and what you are asking the model to do is read it — to tell you what reads badly, what is redundant, what is missing and where it sounds off. It is a request with its own rules, because the risk of it inventing something moves elsewhere: it is no longer in what it writes, it is in what it makes you change in your own text without needing to — a change you make on its say-so, not because it was actually wrong.

The whole thing in one sentence. When it reviews, the model has no reference document to check your text against — it does not know whether your writing is correct, only whether it sounds right — so its opinion on style is worth a lot and its opinion on the facts your text contains is worth nothing, and the two have to be treated completely differently. Confusing the two is the most common mistake in this use, and it usually happens because both kinds of answer arrive in the same confident tone, with nothing in the format to distinguish a well-founded opinion from an unverified claim.

What you can ask for, and what you cannot

What you askReliability
"Does this sentence read clearly?" High. Judging clarity and structure is exactly what a language model does best, because it is pure judgement about form, not about outside data.
"Is anything redundant, does any idea repeat?" High, for the same reason: it is a question about the structure of the text itself, which it has in front of it in full, not about the world outside the text.
"Is this fact I put in correct?" Low. Here it is no longer judging your text: it is answering a question of fact, which is exactly the territory of the hallucinations lesson — it needs verifying against a source, not against its opinion of what you wrote.
"Is anything important missing that should be there?" Medium. It can flag obvious structural gaps — an instructions document with no contraindications section — but it cannot know whether a specific detail is missing if you never told it that detail exists.
The most expensive trap in this use. If you paste a text with a factual error and ask it to review it, the review can easily come back focused on style and say nothing about the underlying error — because you did not ask about that, and a model tends to answer the question it was asked, not the one it should have been asked. The absence of a flag about a content error does not mean there is none: it means you did not ask about it, and it is still your responsibility to check it elsewhere.

A trick that multiplies how useful this is: give it a concrete role

"Review this" on its own tends to produce a correct but generic answer. It works much better to ask it to review from a concrete role, because that gives it a clear standard to judge against instead of a vague notion of "well written":

The role does not change the underlying reliability — it still cannot verify facts, only judge form — but it changes what you get back a great deal, because it gives it a concrete standard instead of letting it pick a generic one on its own, and a concrete standard is something you can push back on if the feedback still does not feel right.

A full example, and what is wrong with it

You have written a shop-window sign advertising the medication review service, and you ask the model to review it before printing.

Your original text: "Do you take more than five medicines? Come in for a complete free review of your medication, no appointment needed, and we guarantee you'll have no dangerous interactions."

What the review says

"The message is clear and the opening question hooks well. I'd suggest shortening the last sentence so it fits a sign better: something like 'complete, free review, no appointment needed'. Also consider whether 'complete' adds anything or could be cut to save space."

And now, what is wrong with settling for just that review:

  1. The style review is good and worth acting on. Shortening the text for a sign is sound advice, and it is exactly the kind of improvement this use delivers best.
  2. And the real problem, which was not a style problem, got missed. "We guarantee you'll have no dangerous interactions" is a claim no review can honestly guarantee — it is exactly what the medication review lesson (a Level 3 lesson) explains cannot be promised without knowing the case — and on top of that it may be a problematic promise from a healthcare-services advertising standpoint.
  3. The model did not flag it because you did not ask it to. You asked for a style review and got one; you did not ask it to check whether the content was a safe claim to make, and that is a different question that has to be asked separately, explicitly.
  4. The lesson: ask for two separate reviews, not one. One about style — "does it read well, is anything redundant, does it fit the space?" — and one about content — "is there any claim here I shouldn't be making, any promise that cannot be kept?" — because they are two questions with completely different reliability, and mixing them into a single request lets the style question hog all the attention, leaving the content question skimmed over even when it was the one that actually mattered.
