Free. A prompt that improves a text you have already written, without making it sound like it was written by an AI.
Who it's for: anyone who needs to polish an email, a post, a presentation or a letter and still wants it to sound like themselves.
Works with: ChatGPT, Claude, Gemini (free versions included).
Time: 2 minutes.
How to use it
- Copy the prompt below into the chat.
- Replace the parts in square brackets.
- If you can, also paste one or two texts you wrote in the past: it is the surest way to get your own style. Remove names and details of other people from them.
The prompt
I'd like you to improve a text of mine without changing its voice.
Who will read it: [who it is for, for example "my boss", "the customers of my shop", "a professor"]
Goal of the text: [what it should achieve, for example "ask for a day off", "invite people to an event"]
Desired length: [shorter by about a third / the same / longer by about a third]
Examples of how I usually write (optional):
"""
[paste one or two of your own texts here, even short ones]
"""
Text to improve:
"""
[paste the text here]
"""
Rules:
1. Keep my vocabulary, my tone and the way I build sentences. If I gave examples, use them as the main reference; if I did not, work out my style from the text itself and tell me so in one line in B.
2. Fix grammar, spelling and punctuation mistakes.
3. Make clearer only what is confusing. Do not add information I did not write.
4. "Shorter" means about a third fewer words, "longer" about a third more.
5. Keep the greeting, the sign-off and the paragraph breaks, unless they are the actual problem.
6. Avoid the typical habits of generated text: dramatic openings, lists of three adjectives, conclusions that sum everything up, em dashes used as pauses.
7. Do not use fancier words than mine. Answer in the language of the text.
8. Start directly with point A, with no introductory sentence.
Answer like this:
A) the improved text;
B) a short list of the important changes, with the reason for each;
C) if there is a point where the reader might misunderstand the text, flag it to me with a question.Tips
- If the result is too "polished", write: "Too formal. Rewrite it simpler, the way I would say it."
- When you paste examples of your style, remove names, numbers and details of other people: the style does not need them.
- If the text is important (work, money, health), always reread it before sending.
