How to use AI for social media without sounding like a robot

AI writing tools are good at producing text that sounds like the average of everything they have read. That is exactly the problem for a small business. Your customers follow you because you are not average: you know their names, your street, your stock and the odd things that happen on a Tuesday. If you give a tool nothing specific, it fills the gap with safe, general phrases, and readers notice.

The fix is rarely a cleverer prompt. It's better input and a proper edit. Before you change anything, learn to spot the tells. If a draft has three or more of these, rewrite it rather than tweaking it.

• Grand openers that could start any post: "Are you ready to...", "In a world where...", "Let's dive in".
• No specifics: no names, days, prices, places, product details or numbers you can check.
• Lists of three adjectives ("fresh, local and delicious") in every other sentence.
• An emoji at the end of every line and a block of hashtags nobody would search for.
• Questions no customer would answer, such as "What does community mean to you?"
• Every post built the same way: hook, three points, question, call to action.
• Claims you can't back up, such as "the best in town" or "loved by thousands".
• Long captions that wander away from what the photo or video shows. Instagram lists long captions unrelated to the underlying content among the low-quality content it tries not to recommend.

The most useful habit is to collect raw material before you open any AI tool. Raw material is anything that only your business has: what happened today, what a customer asked, what you changed and why. The tool's job is to shape it, not invent it.

Here is the difference for a hypothetical florist writing about wedding flowers.

1. Keep a running note on your phone called "post material". Add one line whenever something happens worth sharing.
2. Record a two-minute voice note after a job or a busy day, then paste the transcript into the tool as the starting point.
3. Save the exact words customers use in messages and reviews (with names removed). Their wording is usually better than any marketing phrase.
4. Keep a short fact sheet: opening hours, prices, lead times, service area. Paste it in so the tool doesn't guess.

Treat the tool like a junior writer you are briefing, not a vending machine. Ask for material you can choose from and react to. You will get further, faster, by picking the best of three first lines than by accepting one full post.

• Ask for three different opening lines and pick one, or combine two.
• Ask the tool to interview you first: "Ask me five questions about this job before you write anything."
• Set a length: "Under 80 words" stops padding better than "keep it short".
• Name what to avoid: "No exclamation marks, no emojis, don't use the words 'passionate' or 'journey'."
• Paste two of your own past posts and say "match this tone". Examples work better than adjectives.
• Ask for a plain version and a playful version, then decide which suits the moment.

Editing is where a draft becomes yours. Five short passes take a few minutes once you are used to them, and each catches a different problem.

1. Facts: check every name, price, date, time and claim against your fact sheet. Delete anything you can't prove.
2. First line: rewrite it so it says something specific. If it could open any business's post, it isn't good enough.
3. Your detail: add one thing only you could know, such as the customer's question, the weather that morning or the mistake you fixed.
4. Cut: remove about a fifth of the words. Filler phrases, repeated points and stacked adjectives go first.
5. Read aloud: if you wouldn't say it to a customer at the counter, change it until you would.

Here's how one post changes when the owner follows the steps above. The business and details are invented for illustration.

Most robotic phrasing comes back again and again. A short house-style list, pasted into every request, stops you fixing the same things each week. Keep it to one screen so people actually use it.

Our free brand voice guide template has space for these rules, and our guide to keeping your brand voice consistent with AI covers how to write and test them.

• Words we never use: list the ten that keep appearing in drafts and that you would never say.
• Spelling and style: British or American spelling, how you write prices and times, whether you use first names.
• Emoji and hashtag habits: how many, where, and which ones are yours.
• How we sign off: the exact phrase for booking, ordering or visiting.
• Claims we don't make: "best", "cheapest", guarantees, health or financial promises.

Some posts carry more risk than a dull caption. Write these yourself, or at least check every word before they go out.

If you use AI to make realistic video or audio, check the platform's labelling rules before posting. Meta, for example, requires a label on content with photorealistic video or realistic-sounding audio that was digitally generated or altered, and gives a reel narrated with a realistic AI voiceover as an example. Our guide to AI content labels on each platform covers the rest.

• Replies to complaints or bad reviews. People can tell when a reply is generic, and it makes things worse.
• Anything sensitive: illness, bereavement, local tragedies, politics, religion.
• Results and promises: before-and-after claims, health, money or legal outcomes.
• Customer stories, unless the customer has agreed and checked the wording.
• Realistic images or voices of real people, including your staff, without their permission.

Zolyp, which we make, is built around the raw-material approach above. Its Brand Brain holds your tone of voice, audience, services and banned topics, so drafts start from your business rather than a blank prompt, and it learns from every edit or rejection you make. You can add your own photos, ask for up to six posts at once, keep the ones you like and change the rest. It publishes to Instagram, Facebook, LinkedIn, Google Business, X, TikTok, YouTube, Pinterest, and Threads, and nothing goes live until you approve it. Lite is $9 a month per brand if you only want to schedule posts you make yourself; the plans that create posts start at $29 a month, with a 3-day free trial.
