A reception notice says, “Reservations are held until 6 pm unless you have confirmed a later arrival with reception.” An AI rewrite returns, “Reservations expire at 6 pm.” The second sentence is shorter and easy to read. It also removes the exception a late-arriving guest needs.
This illustrative case explains why judging an edit by the rewrite alone is risky. The revised sentence gives no clue that something important disappeared. A reviewer needs the original rule beside it.
The edit changes a decision
A visitor who arranged a late arrival may read the original and keep the reservation. The rewrite could lead that same visitor to cancel or make another booking. The problem is not a preference for longer wording; the two notices support different actions.
A more faithful revision could read:
We hold reservations until 6 pm, except when you have arranged a later arrival with reception.
That version changes the sentence structure while keeping the time and exception. It still needs approval from whoever owns the reservation rule. If “confirmed” has a specific operational meaning, even “arranged” may be too loose.
When deciding how to edit AI writing, focus first on changes to what a reader can reasonably do or expect. Names and numbers are visible checkpoints, but small words such as unless, may, only and expected often carry the rule.
Source-linked notes make the change inspectable
The Writing Editor returns revised text and a bounded list of notes that quote original passages. Those quotes help a reviewer locate the relevant sentence rather than search a long draft for a vague comment about clarity.
A quote is an anchor, however, not an approval. The words can genuinely exist in the source while the explanation overlooks an exception. The notes are also not a complete redline of every difference. Read the full revised notice and its surrounding paragraphs before accepting it.
Grammar and spelling is a sensible starting mode when a policy is settled and only language errors need correction. Rewrite or Simplify can change more structure, which creates more decisions for the reviewer. A polished tone cannot settle an ambiguous rule.
Decide who can approve the change
Separate wording changes you can approve from rule changes that need an owner. Correcting a repeated word may be routine. Removing the late-arrival exception requires someone to confirm whether the service has changed.
If the source itself is unclear, pause the publication of that sentence and ask a concrete operational question: what happens to a reservation after an approved late arrival? Preserve the uncertainty in your working draft until the answer is known.
Keep the original and the approved version together. For private operational material, remove booking details or guest information before sending text to the site's configured AI providers. The final record should let a future editor see which wording changed and which rule someone actually authorized.
