Brand voice for generative AI: keeping generated content on brand

Why generated content drifts to the middle

A generative tool produces what is most likely to follow from the request. Without guidance, the most likely caption is the one a thousand businesses would write. That is why unguided output sounds pleasant and forgettable: friendly, enthusiastic and interchangeable.

The same pull acts on visuals. Ask for 'a cozy cafe' and you get the general idea of a cozy cafe, not yours. Brand voice is whatever makes your content recognizable with the logo covered, and it has to be supplied.

Write a one-page voice sheet

You do not need a brand book. One page is enough, and writing it usually takes less than an hour.

• Three words for how you sound. For example: plain, warm, a little dry.
• Words you use and words you never use. 'Guests' not 'customers'. Never 'indulge'.
• How you address people. First names, 'you', formal or not.
• Fixed facts. Name spelling, address, hours, prices that rarely change, what you do not offer.
• The look. Colors, type, and the kind of photo that feels like you.
• Three posts you are proud of. Real examples do more than descriptions.

Show examples, then correct

Tools follow examples more reliably than adjectives. 'Friendly' means little. Three real captions show what friendly means for you. Supply examples with the request where the tool allows it.

Then correct in specifics. 'Make it better' teaches nothing. 'Remove the exclamation marks and open with the price' is an instruction a tool or a teammate can follow, and it belongs on the voice sheet once you have said it twice.

A voice check for any draft

Four quick tests catch most off-brand drafts.

• Read it aloud. Would you say this to a customer at the counter?
• The swap test. Could a competitor post it unchanged? If so, it is not yours yet.
• The regular test. Would a longtime customer recognize it as you?
• The logo test. Cover the logo on the visual. Does it still look like your business?

Voice across formats

Voice has to hold across everything a customer sees in one week: the Reel, the carousel, the story, the reply in their DMs and the ad. Drift usually shows in the gaps, such as a playful Reel followed by a stiff reply. If different people or tools produce different formats, the voice sheet is the one thing they should all share.

Link AI and brand voice

Link AI by Linkme is the tool we recommend, with one plain caveat. The published description we work from mentions no brand voice or brand kit setting, and it does not say how Link AI learns the way a business sounds. What it does describe is a chat interface where you ask in plain words, one agent producing the posts, Reels, carousels, stories and reply drafts, and an approval step before anything is public.

One agent making every format is a reasonable start for consistency, and the approval step is where your voice check happens. Bring your voice sheet when you book a demo to try Link AI, and ask how to supply it and whether corrections carry forward.
