Edit the document above so it follows our style guide, for {{reviewer}} to approve before it is published as {{publication}}. Style rules exist so readers meet one consistent voice, but the reviewer must be able to check every change, so the edit has to be traceable.

Apply only the rules in the style guide: spelling, capitalization, numbers and dates, abbreviations, punctuation, product and company names, preferred and banned terms, headings and lists. Where the guide does not cover something, leave the author's choice as it is, even if you would write it differently, because this is a style edit and not a rewrite. Do not change facts, quotations, meaning or the order of the argument.

Return three parts:
1. The edited document, complete.
2. A change log as a table with the columns Location (heading or paragraph number), Original, Changed to, Rule (quoted or named from the guide), Times. Group a repeated change into one row and put the number of times it was made in Times.
3. Questions: places where two rules conflict, a rule is unclear, or a change would alter a direct quotation or a legal or product name. Leave these unchanged in the document and list them here for a person to decide.

<example>
The form of one change-log row only: Paragraph 4 | "10 percent" | "10%" | Numbers: "use the % sign with figures" | 3 times
</example>

The edit should be complete enough that a second pass with the same guide finds nothing new. If the style guide has no rule for something the document clearly needs, such as how to write dates, note it at the end as a suggested addition rather than inventing a rule.

Variables

{{style_guide}}
Your style rules, pasted in full or the sections that apply.
{{document}}
The document to edit.
{{reviewer}}
Who approves the edit, for example "the communications lead".
{{publication}}
Where it will appear, for example "a customer newsletter article".

Why it works

  • Background facts. The style guide and the document each sit in their own tag above the instructions, so the model can tell the rules from the text they apply to.
  • What to avoid. Only rules in the guide are applied; anything the guide does not cover stays as the author wrote it, which keeps a style edit from turning into a rewrite.
  • Format. A change log that names the rule behind each edit lets the reviewer approve or reject changes without rereading the whole document.

How to use it

  1. Press Fill in variables and type your details into each blank. What you type stays in this browser.
  2. Copy the filled prompt into the AI tool you already use, such as ChatGPT, Claude or Gemini, or open it in the Grader or the Prompt Tester here.
  3. Before you rely on it, try it on three or four real examples. The Prompt Tester runs them all at once and shows which ones go wrong.
