You open ChatGPT, type “make a nice post for my bakery”, and what comes back could belong to any bakery on earth. Generic caption. Three hashtags you’d never use. Nothing about your shop, your prices, or the fact that you close at six.
So you close the tab and go back to writing posts by hand — which takes an afternoon you don’t have.
The tool isn’t the problem. The instruction is. Here is what actually changes the output.
Why AI writes generic marketing
An AI model knows a great deal about bakeries in general and nothing at all about yours. It has never seen your counter, doesn’t know that your cinnamon rolls sell out by noon, and has no idea that most of your orders arrive on WhatsApp rather than through a website.
When you write five vague words, the model fills every gap with an average. Average is what generic means. You didn’t get a bad answer — you got the only answer your question allowed.
The eight things every brief needs
A usable brief answers eight questions before it asks for anything. You can write it on the back of an envelope:
- Who you are. “Anjali’s Kitchen, a home bakery in Bengaluru.”
- What you’re selling right now. Not your whole menu — one thing. “Fresh cinnamon rolls.”
- The offer. “Rs. 199 for a box of two.”
- Who it’s for. “Families ordering weekend breakfast.”
- Your brand’s voice. “Warm and homely. Not corporate. No exclamation marks.”
- Where it will be posted. An Instagram caption and a WhatsApp status are different lengths and different tones.
- The call to action. “Order by 6 PM on WhatsApp.”
- What to avoid. “Don’t invent discounts. Don’t claim we’re the best in the city.”
That last one matters more than people expect. Left unchecked, AI cheerfully invents offers you never made and superlatives you can’t back up — and those go out under your name.
The same product, the same afternoon
Take the vague version first: “Make a nice bakery post.” What comes back is a pleasant photo caption with no business name, no price, and no instruction to the reader. Nobody who sees it knows how to buy anything.
Now the same request with the eight parts filled in. What comes back names Anjali’s Kitchen, leads with the weekend special, states Rs. 199 for a box of two, and ends by telling the reader to order by 6 PM on WhatsApp. It sounds like the shop, because the brief described the shop.
Same tool. Same afternoon. The only thing that changed was the instruction.
Write the brief once, use it every week
Here is the part that saves real time: seven of those eight answers never change. Your name, your voice, your audience, your platform, your call to action, your rules — those are fixed. Only “what am I selling this week” moves.
So write the brief once, keep it in a note on your phone, and each week swap out a single line. A post that used to take an afternoon takes about five minutes, because you are no longer starting from nothing.
A template you can copy
Paste this into any AI tool and fill in the square brackets:
You are writing a social media post for [BUSINESS NAME], a [TYPE OF BUSINESS] in [CITY].
This week we are promoting: [PRODUCT].
The offer is: [PRICE / DEAL].
Our customers are: [WHO].
Our tone is: [VOICE] — do not sound corporate.
This will be posted on: [PLATFORM].
End with this call to action: [CTA].
Do not invent any offer, discount or claim I have not given you here.
Read what comes back before you post it. If a price or a promise appears that you didn’t write, delete it. The brief reduces invention; it doesn’t eliminate it.
Does this need a paid tool?
No. The free tiers of the major AI assistants are enough for writing captions and post copy. Paid plans get you faster responses and higher limits, not better output — a clear brief on a free tool beats a lazy prompt on an expensive one.
Start here
Pick one product you’re selling this week. Write the eight lines. Run it once. Compare it to what you’d have got from “make a nice post”.
That comparison is usually enough to convince people, because the difference isn’t subtle.
If you’d like this laid out step by step, there’s a 37-minute course that walks through the whole process — writing the brief, generating the post, and publishing it — using a home bakery as the worked example. The first chapter is free to watch, no sign-up required.
