How to edit and proofread with AI without losing your voice

You ask AI to "improve" your writing and get back something different: longer, stiffer, full of phrases you'd never use. The content is similar, but it no longer sounds like you. That happens because "improve" is an open-ended instruction, and models lean towards rewriting. The fix is to say exactly how much intervention you want.

#Three levels of editing

Before asking for anything, decide what you need:

Most of the time you want level 1 or 2 — but unless you say so, AI tends to do level 3.

#Prompts for each level

#Level 1: errors only

Correct only the spelling, punctuation and grammar mistakes in this text. Don't change correct words, don't reorder sentences and don't alter the tone. Return the corrected text and, below it, a list of every change: original → correction, with a brief reason.

The change list is key: it lets you learn from your mistakes and reject edits you disagree with.

#Level 2: clarity without losing your voice

Edit this text to make it clearer. You may split very long sentences, remove repetition and fix errors, but keep my vocabulary, my informal tone and the first person. Don't add new ideas or clichés. Put any changed passages in bold.

#Level 3: targeted rewriting

Adapt this text, written for my team, into an email for a client who doesn't know our project. Professional but friendly, 150 words max. Keep the three key facts: delivery date, cost and next step.

#Teach the AI how you write

If you edit with AI often, give it a sample of your style:

Here's something I wrote that represents my style well: [paste a paragraph]. Notice my sentence length, vocabulary and tone. From now on, when I ask for edits, respect that style.

Some tools let you save custom instructions so you don't have to repeat this in every chat.

#Language questions: check reference sources

Language models get most routine corrections right, but they can stumble on:

• Contested or changing usage, such as singular "they", split infinitives or "data is/are".
• Regional variants: US vs UK spelling (color/colour, -ize/-ise) and vocabulary. Tell it which one you use.
• House styles: AP, Chicago, APA and others differ on commas, numbers and capitalisation. Name the style guide you follow.

For these, check a reference: a current dictionary such as Merriam-Webster (US) or your organisation's style guide. For public-facing or official writing, the US government's plain language guidelines are a useful, free reference on clear writing.

#Especially useful requests

• Spot repetition: "Flag words repeated in nearby paragraphs and suggest synonyms only where the meaning stays the same."
• Check coherence: "Are there contradictions or logical jumps between paragraphs?"
• Adjust length: "Cut this to 200 words without losing any facts."
• Check the register: "Does this email sound too blunt to send to a client?"
• Read as the recipient: "Read this as someone with no technical background. What wouldn't you understand?"

#Common mistakes

• Accepting every change without reading. AI sometimes "fixes" things that were fine.
• Asking it to "improve" without specifics. You'll get a rewrite.
• Editing assessed academic work without checking whether that's allowed. Proofreading is often permitted where rewriting isn't — check your institution's policy.
• Pasting text containing other people's personal data, such as reports or case files, into unapproved tools.

#The bottom line

To edit with AI without losing your voice, set the level of intervention, ask for a change list and check doubtful points against a reference. You'll get cleaner writing — and learn from your own mistakes along the way.
