Keep Your Personal Brand Voice When Using AI: Write a “Voice Guide” So Drafts Sound Like You

Viewers don't follow you for perfect grammar. They follow you for how you talk, joke, emphasise and tell stories. That's your voice. The catch is that AI's first draft usually sounds like every other channel: “Hello everyone, today I'm introducing an amazing product…”. If you want to use AI without losing yourself, you have to teach it on purpose.

What your voice is actually made of

Don't stop at “friendly” or “professional.” Voice is the sum of small details: sentence length, how you address viewers, regional words you like, your kind of humour, how you open and close a live, and the things you would never say. The more specific you are, the easier it is for AI to imitate and for you to check.

Step 1: write a short voice guide

A voice guide is a one-page note describing how you communicate. Write it in your own words, around 150–250 words, covering:

• How you address people: first-person pronouns, how you call your audience.
• Three to five adjectives for your tone, each with a short example.
• Phrases you use often and phrases you want to avoid, such as clichéd sales lines.
• Rhythm: short or long sentences, whether you ask the audience questions.
• Boundaries: topics you skip and kinds of promises you never make.

Step 2: feed it real examples

Description alone isn't enough. Paste in three to five passages you actually said or wrote, such as a transcript of a live or a few captions you're proud of. AI picks up voice from examples faster than from adjectives. Use only your own material; don't paste other people's work to imitate it.

A sample prompt you can adapt

You are my writing assistant. Write following the VOICE GUIDE and EXAMPLES below.

VOICE GUIDE:
- Casual and warm, a little humorous, short sentences.
- I speak in first person and say "you all" to viewers.
- Avoid: "amazing product", "don't miss out".
- Never state benefits or prices I haven't given you.

EXAMPLES (written by me):
1) [paste passage 1]
2) [paste passage 2]
3) [paste passage 3]

TASK: Write a 60-second opening for a live introducing [product name]. Real facts: [list them]. If information is missing, ask me instead of making it up.

Step 3: edit like a collaborator

Treat the AI draft like a draft from a new teammate. Read it aloud: wherever you stumble or feel awkward, it isn't your voice. Swap clichés for your own phrasing and add a detail only you know, like a real experience of using the product. Then update your voice guide with the edits you keep making. After a few rounds the drafts will land closer to you.

Traps to avoid

• Posting the draft without rereading it.
• Letting AI add specs, prices or promises. Always verify product information yourself.
• Using the same sentence template for every live, which makes your channel sound repetitive.
• Forgetting to check each platform's latest rules on AI-assisted content and product promotion.
