AI can write product descriptions quickly, but without guidance every description sounds slightly different. A brand voice for AI product content fixes that by telling the AI who you are, who you sell to and which words to use or avoid, so every draft sounds like your store.
This tutorial explains how to define a brand voice, apply it across your catalog with Siteryn AI Product Content Pro and review the results before publishing.
Quick answer
To set up a brand voice for AI product content, define your tone, describe your audience, list words to use and avoid, save them as a brand voice profile, apply a content template and review every draft before publishing. Siteryn AI Product Content Pro adds brand voice profiles and content templates, so tone, audience and words to avoid apply to every draft you generate.

What is a brand voice profile?
A brand voice profile is a saved set of instructions that describes how your store sounds, including tone, target audience and words to avoid, so an AI tool can apply the same style to every product description it drafts.
Before you start
- WordPress 6.4+, WooCommerce 8.0+ and PHP 7.4+.
- Three or four existing descriptions you like. They show your real style.
- Clean product data: titles, attributes and key facts. See Bulk AI Product Descriptions for WooCommerce Stores.
- A review process. Read AI Hallucinations in WooCommerce first.

Step-by-step: how to set up your brand voice
- Write your voice in plain words. For example: “Friendly, clear and practical. No hype.”
- Describe your audience. Who buys, and what do they care about?
- List words to use and words to avoid. Add banned phrases such as “game-changer” or “revolutionary.”
- Create a brand voice profile in AI Product Content Pro and paste in these details.
- Choose or create a content template. Set the structure, such as a short intro, benefit bullets and a closing line.
- Generate drafts for a few products and compare them with your favorite examples.
- Adjust the profile until the drafts sound right, then reuse it on every product.
How do you write a strong brand voice brief?
To write a strong brand voice brief, describe your tone in a few clear words, name your audience, give two or three examples of good writing, list phrases to avoid and add facts the AI must never invent, such as prices, guarantees or specifications.
| Brief element | Weak example | Strong example |
|---|---|---|
| Tone | Nice and professional | Warm, direct and practical, with short sentences |
| Audience | Everyone | Busy parents buying durable kids’ clothing |
| Words to avoid | None | “Revolutionary,” “best ever,” “must-have” |
| Rules | Be accurate | Use only the facts supplied. Never invent features. |
Review before you publish
- Check every spec, size and material against your product data.
- Make sure similar products do not share near-identical text.
- Edit anything that sounds generic.
- Publish as drafts first, then in small groups.

Common problems and fixes
| Problem | Likely cause | What to try |
|---|---|---|
| Drafts sound generic | Brief is too vague | Add examples and specific words to avoid |
| Wrong details appear | Product data is incomplete | Fill in attributes and add a rule not to invent facts |
| Descriptions look identical | Same inputs for similar products | Add distinct attributes or notes per product |
| Tone drifts between batches | Different prompts used | Use the saved profile and template every time |

Frequently Asked Questions
Can I use more than one brand voice?
If your store sells to different audiences, separate profiles can make sense. Keep each one clear and test it with a few products first.
Does a brand voice stop AI from making mistakes?
No. A voice controls style, not facts. You still need accurate product data and a human review.
How long should a brand voice brief be?
Short and specific works best. A few lines on tone, audience, examples and words to avoid is usually enough.
Do I need Pro for brand voice profiles?
Brand voice profiles and content templates are part of AI Product Content Pro. You can try the free version first to see the core features.
