Your posts sound one way, your emails sound another, and your website sounds like a third person wrote it. Customers may not notice each difference, but together they make a brand feel scattered.
This guide gives you ChatGPT prompts for brand voice that help you define how you sound and keep it consistent. You will get prompts to describe your voice, write in it, check drafts, and avoid the mistakes that make AI copy sound generic. The AI follows your voice, and you decide what that voice is.
Use the cheat sheet below as a quick reference. Then read on to see when to use each prompt and how it looks filled in.
How to Use These Prompts
Words in [brackets] are blanks. Replace each one with your own details before you send the prompt.
Before: Describe my voice: [samples]
After: Describe my voice: "Fresh loaves are out. Come early, they go fast." "Rainy day? We saved you a warm seat." "Thanks for supporting a small neighborhood bakery."
Use samples of writing that you truly like and that sound like your brand. These prompts work the same way in ChatGPT, Claude, and Gemini. Treat every draft as a starting point, and read it aloud before it goes live.
Define Your Voice
Describe my voice: [samples]
Start with writing you already like. Paste a few real samples and ask the AI to describe the patterns it sees, such as sentence length and tone. Check whether the description feels right to you.
Example: Describe my voice: "Fresh loaves are out. Come early, they go fast." "Rainy day? We saved you a warm seat." "Thanks for supporting a small neighborhood bakery." Note sentence length, tone, and word choice.
Voice in 5 words: [brand]
A few clear words make a voice easy to remember. Ask for five words that describe your brand’s tone, then keep the ones that fit. Back each word with an example later.
Example: Voice in 5 words: a family-run neighborhood bakery that is warm, simple, and a little playful.
Do and don’t list for [brand]
A short list of dos and don’ts turns a voice into rules a team can follow. Ask for a one-page list based on your samples. Edit it until it matches how you really want to sound.
Example: Do and don't list for Sunny Side Bakery, a warm and simple brand. Give 5 dos and 5 don'ts with a short example for each.
Words we use and avoid
Every brand has favorite words and words it never uses. This prompt builds a short list from your samples. Share it with anyone who writes for you.
Example: Words we use and avoid, based on these samples: "Fresh loaves are out." "Come early, they go fast." "Hello, neighbor."
Audience: [customer type]
Your voice should fit the people you serve. Describe your customers and ask how your voice could adjust for them without changing its core. Use what you know from real conversations.
Example: Audience: busy parents and local office workers who stop by for breakfast and treats on the way to work.
Write in Your Voice
Write [copy] in my voice
Once you have voice notes, ask the AI to draft new copy. Include the notes in the prompt so it has something to follow. Edit the result to sound like you.
Example: Write a short announcement for our new cinnamon bun in my voice: warm, simple, a little playful. Keep it under 50 words.
Rewrite this to match: [paste]
Text from a teammate or a past draft may not sound like you. This prompt brings it back in line. Compare the new version with your voice notes.
Example: Rewrite this to match our voice: We are delighted to announce the introduction of our new seasonal pastry offering.
3 tones for [message]
The same message can sound very different. Ask for three versions in different tones, and see which one feels most like your brand. Use the comparison to refine your voice notes.
Example: 3 tones for a message about our extended Saturday hours: warm, playful, and straightforward.
Product blurb in our voice
A product description is a good test of your voice. Give the AI real facts about the product and ask for a short blurb. Check that every detail is accurate.
Example: Product blurb in our voice for a seeded sourdough loaf, baked daily, 1 pound, good for toast and sandwiches. Under 40 words.
Email in our voice: [goal]
An email is another place voice can drift. Give the goal and the key facts, and ask for a draft. Edit it before you send.
Example: Email in our voice: invite regular customers to a free tasting of our fall menu on Saturday morning.
Keep It Consistent
Review this for voice: [paste]
Paste a draft and ask the AI which lines do not sound like your brand. Use the notes as a prompt for your own edits. Do not accept every change blindly.
Example: Review this for voice and flag lines that do not sound warm and simple: Our artisanal offerings are crafted with premium ingredients for the discerning customer.
Make a voice checklist
A checklist makes it easy to review any piece in a minute. Ask for five questions to ask before publishing. Keep it where your team can see it.
Example: Make a voice checklist with 5 yes-or-no questions for our warm, simple, playful bakery brand.
Compare 2 drafts: [A] [B]
When two drafts are close, comparing them can help you decide. Ask the AI which one fits your voice better and why. Make the final call yourself.
Example: Compare 2 drafts. A: "Fresh bread, hot out of the oven." B: "We proudly present our freshly baked bread selection." Which fits our warm, simple voice better?
Create a style guide page
A one-page style guide gathers your voice, word list, and examples. Ask the AI to organize your notes into a simple document. Keep it short so people use it.
Example: Create a style guide page from these notes: our voice is warm, simple, and a little playful. Include word choices and two examples.
Train a new writer on [voice]
New teammates need a quick way to learn your voice. This prompt drafts a short guide with examples of good and off-brand writing. Review it before you share it.
Example: Train a new writer on our bakery voice with a short guide, three good examples, and three off-brand examples.
Common Mistakes
Vague voice words
Words like “friendly” and “professional” mean different things to different people. Back each word with a real example. Quick fix: write one sentence that sounds like your voice and one that does not.
Sample too small
One short sample gives the AI very little to learn from. Share several pieces of your best writing. A mix of formats, such as posts, emails, and web copy, works best.
Copying another brand
Borrowing another brand’s voice can make you sound unreal. Build yours from your own values and customers. Use other brands for inspiration, not as a template.
Skipping a human edit
AI can drift from your voice, especially in longer drafts. Read every draft aloud before it goes live. Change anything that does not sound like you.
Sharing confidential text
Do not paste private customer messages or confidential company documents into an AI tool. Use public writing, such as published posts, as your samples.
Pro Tip
Paste three to five pieces you love and ask the AI to describe the voice. Save that description, and paste it at the top of future prompts.
Example: Here is my saved voice description: warm, simple, a little playful, short sentences, no jargon. Use it to write a short post about our new pumpkin loaf.
FAQ
Can ChatGPT learn my brand voice?
It can follow a voice when you describe it and give samples. It does not remember you in the way a person does, so include your voice notes in prompts. Always edit the result.
What is a brand voice?
It is how your brand sounds in writing, including its tone, word choices, and style. A clear voice makes your posts, emails, and pages feel like they come from the same place.
How do I keep AI copy from sounding generic?
Share real samples, define your tone, and add specific details only you know. Then edit by hand. Generic copy often comes from generic prompts.
Final Thoughts
A consistent voice builds trust over time. Use these prompts to describe how you sound, write in that voice, and check your drafts. Keep your edits human, and keep private customer information out of the chat.
