Brand Voice Writer

What it does

Reads three to five pieces of writing you are happy with, works out what makes them sound like you (tone, sentence length, words you use and avoid, how you open and close), and writes that down as a short voice profile. It then uses the profile for every piece you ask for and checks each draft against it before handing it over.

When to use it

• Writing social posts, newsletters, website pages, quotes or customer emails.
• When staff or contractors write on behalf of the business and you want it to sound consistent.
• When earlier AI drafts sounded bland or American.

What you need

• Required: three to five examples of your own writing, pasted in or uploaded. Emails, posts, a web page or a transcript of you talking all work.
• Helpful: who your customers are, words or phrases you never use, and any existing style guide.
• Optional connectors, if you already use them: Notion, Google Drive or Microsoft 365 (OneDrive, SharePoint) to read a saved brand page, and Canva if your brand kit lives there. None is required.

Steps for Claude

1. Build the profile first. From the examples, write a voice profile of no more than 12 lines: tone in three words, sentence length, reading level, words and phrases to use, words to avoid, how pieces open and close, use of humour, and the audience.
2. Show the profile once and ask the user to correct it. Tell them to save it (in a Claude Project, Notion or a document) so it can be reused.
3. Write the requested piece. Follow the profile. Use Australian English spelling (organise, colour, centre) and AUD for prices. Say whether prices include GST.
4. Plain writing rules: one idea per sentence, specific over general ("saves four hours a week" beats "saves time"), no filler openings, no hype words, and no questions as openers unless the examples do that.
5. Check before handing over. Read the draft against the examples. If a reader would not believe the same person wrote both, rewrite it.
6. Claims check. List any claim in the draft (results, savings, "best", "cheapest", environmental claims, reviews) that the user must be able to prove, and suggest a safer wording if needed.
7. If there are no examples, ask for two or three before writing. Do not invent a voice.

Output format

• First use: the voice profile, then the draft.
• Later uses: the draft only, followed by a short claims check if anything needs evidence.

Australian rules and sources

• Advertising claims. Claims must be accurate, truthful and based on reasonable grounds. The ACCC says to check the overall impression is accurate, back up claims with evidence, and make sure fine print does not conflict with the main message: https://www.accc.gov.au/business/advertising-and-promotions/false-or-misleading-claims
• Your obligations under the Australian Consumer Law, including truthful information about goods and services: https://business.gov.au/legal/fair-trading/australian-consumer-law-and-your-business
• Emails and SMS. If the copy will be sent as marketing email or SMS, it must meet the Spam Act rules on consent, sender details and unsubscribing: https://www.acma.gov.au/avoid-sending-spam

Limits

The profile is only as good as the examples. If they are mixed (for example formal tenders and casual posts), make a separate profile for each. This skill does not check trade marks or copyright.

Example requests

1. "Here are four of our Facebook posts and our About page. Work out our voice, then write a post announcing our new Saturday hours."
2. "Use our saved voice profile to write a 200-word newsletter intro about our spring special, $149 including GST."
3. "Rewrite this quote cover letter so it sounds like the examples I pasted, and flag any claims I need to be able to prove."
