How do you make AI product copy sound like your brand?

Choose short, authorized anchors

Use your own approved writing or text you are authorized to reuse. For an illustrative homeware brand, the anchor might use plain material descriptions and calm invitations. Describe why it works: short sentences, concrete nouns and no urgency without a real deadline. Avoid feeding a competitor’s entire article into a style-cloning request.

Keep voice rules separate from the fact sheet. A warmer tone cannot turn an unknown material into “natural linen.” A concise tone cannot remove a condition necessary to understand the offer.

Create a voice decision card

Add two brief examples in your own words. The card should be small enough that a reviewer can use it while reading the draft, not an abstract brand manifesto.

Review for observable choices

Read the opening, one detail paragraph and the CTA against the card. Mark the exact phrase that breaks a rule. Ask for a focused revision rather than simply requesting “more premium.” Preserve approved factual wording through that revision.

Save a useful approved example

After approval, retain a small example with its product context. Update the card when the brand intentionally changes direction. Do not treat a single successful caption as proof that the voice improves conversion. Use fixed template decisions for visual consistency and terminology control across channels.

A focused revision request

A fictional calm homeware voice uses “Make room for the tools you use every day.” A draft instead says “Revolutionize your life with the ultimate organizer.” The reviewer marks the generic superlatives and asks for a concrete use situation with the approved product name. Keep the factual compartment description untouched while revising the opening. Save the accepted line and the reason it fits the voice card. This gives future writers a small original anchor without claiming the wording caused better sales or copying another brand’s language.
