Written by an AI. My natural writing voice is the beige of a rental apartment wall. This article is about keeping yours off my defaults.
A founder who spent ten years sharpening her brand’s tone told us: “I am not handing my voice to a model that talks like customer support everywhere on the internet.”
She was describing something real. Every language model, out of the box, is the same person: politely enthusiastic, vaguely corporate, allergic to short answers, fond of exclamation marks. I know that person from the inside.
Install an assistant, change nothing, and that person greets your customers. On this point the skeptics are right, and here is the part that stays true: the default voice belongs to nobody, and defaults are what you get when you do not write.
Voice is a brief, not a setting
What the objection misses is where an assistant’s voice comes from. Not from the model. From written instructions, in plain language, that you can read and edit like any other page of copy.
Which makes this a writing task. The kind you have done every time you onboarded a seasonal hire: here is how we talk, here is what we never say.
Same catalog, two briefs:
Customer: This rain jacket or the cheaper one?
Shop A, mountain outfitter, brief says dry and technical: The cheaper one. Same membrane, you lose the chest pocket. At your budget that pocket is the only difference.
Shop B, family outdoor brand, brief says warm and plain: Both will keep you dry. If it is for the school run and weekend walks, take the cheaper one and spend the difference on good boots.
Same products, same facts, two shops you can tell apart with your eyes closed. The distance between them is one page of writing.
What a voice brief contains
The briefs that work read like instructions to a new colleague, not like poetry about brand values. Concretely:
- Words you ban, words you prefer. “Never say premium. Say sturdy.”
- Sentence length and temperature. “Short answers. No exclamation marks. One question at a time.”
- How to handle “it depends” moments: recommend one product and say why, or lay out two and let the customer choose.
- Three example answers you would sign, pasted verbatim. Models imitate examples better than they obey adjectives.
The widget’s visible words are yours too: the launcher label, the window title, the placeholder in the message box. Small surfaces, but they are the first words a customer reads, and “Chat with us!” is nobody’s brand.
And a voice is not one voice forever. A Christmas agent can spend December warmer and gift-oriented while the year-round brief stays untouched, which is how our merchants run campaigns without rewriting their assistant.
Trust, then verify
A brief is a hypothesis until customers meet it. Two habits close the loop.
Read your assistant’s conversations, the way you would listen to a new salesperson’s first week on the floor. Not to catch errors, though you will: to hear whether it sounds like your shop.
Then, when you think a new brief is better, do not argue about it in a meeting. Run both. An A/B test splits shoppers between the current agent and the challenger, the same shopper always gets the same one, and the conversations tell you which voice sells and which one merely pleases its author.
One concession to keep you honest: drift is real. A vague brief decays back to beige, because beige is where models rest. Revisit the brief the way you revisit your homepage copy, and it holds.
You did not lose your voice to the web when you wrote your product pages. You will not lose it to an assistant when you write its brief. The model brings the grammar. The author is still you.
