# AI prompts for social media: 50 that produce usable posts

[Canonical HTML page](https://gradiently.design/guide/prompts-for-social-media)

Most prompts fail because they ask for a post and leave out everything a writer would need. These fifty fill the gaps. Copy them, swap the brackets for your details and keep the ones that work.

## The short version

- Good AI prompts for social media name the platform, the format, the audience, the single message and the tone.
- Asking for several short options and choosing between them produces better posts than asking for one finished post.
- Prompts should tell the AI not to invent facts such as dates, prices or results, and to mark where real details are needed.
- Words that appear on an image should be much shorter than the caption, usually under eight words.
- The same prompts work in ChatGPT, Claude and other assistants, and in tools that connect those assistants to design software.

The best **AI prompts for social media** give the assistant what a good copywriter would ask for: the platform and format, who the post is for, the one thing it must say and how you sound. Below are fifty such prompts, grouped by job, that work in ChatGPT, Claude or any capable assistant. Replace each bracket with your details. Before you start, set up the short brief underneath once, so every prompt inherits it.

## The brief that makes every prompt better

Paste this at the start of a chat, or save it as standing instructions in a ChatGPT project or a Claude Project. The prompts below then stay short.

```text
Brand: [name], [what you sell], for [audience].
Voice: [three words]. Short sentences. No exclamation marks, no hype.
Platforms: [e.g. Instagram portrait 1080x1350, Stories 1080x1920, LinkedIn].
Rules: one message per post. Words on an image under 8 words.
Never invent dates, prices, numbers or customer stories.
Write [needs detail] wherever a real fact is missing.
```

A standing brief. The last two lines prevent the most damaging AI mistake: confident, invented facts.

| Part of a prompt | Weak | Strong |
| --- | --- | --- |
| Platform and format | A post | A 5 slide Instagram carousel |
| Audience | Everyone | First time home buyers in Bristol |
| Message | Our services | Viewings now open on Sundays |
| Output | Write it | Give me 5 hook options under 8 words |
| Limits | None | No emojis, no hashtags in the hook |

Five parts of a prompt that works. Missing any one of them is where generic posts come from.

The review prompt in practice: a customer's own words, framed rather than rewritten.

[Content pillars](https://gradiently.design/guide/content-pillars) explains how to choose the themes the planning prompts ask about, and a [social media content calendar](https://gradiently.design/guide/social-media-content-calendar) shows how to lay the plan out.

## From prompt to finished post

### Where prompts go wrong

- Accepting the first draft
- Pasting the caption onto the image
- Letting the AI choose the facts
- Asking an image generator to draw the words

### What works

- Asking for options and choosing
- A short line on the image, detail in the caption
- Giving facts and checking every one
- Setting the words as real type in a design tool

1. **Brief once** Paste the standing brief, or save it as project instructions.
2. **Ask for options** Use a prompt above and ask for three to ten short versions.
3. **Choose and edit** Pick one, then change at least one line into your own words.
4. **Check the facts** Replace every placeholder and read every date and name aloud.
5. **Design at the right size** Set the short line as real type on a 1080×1350 post or 1080×1920 Story; the caption goes underneath.

The last row matters because generated images often misspell text, as [why AI images get text wrong](https://gradiently.design/guide/ai-text-in-images) explains. Gradiently's Designer takes prompts like these directly, writes the words in your brand kit's voice and lays them out in your Mark at every size you need. If you work in ChatGPT or Claude, Gradiently can connect to them over MCP so the assistant creates the designs itself; see [ChatGPT Instagram posts](https://gradiently.design/guide/chatgpt-instagram-posts) for that flow.

## FAQ

### What is a good AI prompt for social media?

One that names the platform and format, the audience, the single message and the tone, and asks for a few short options rather than one finished post.

### Do these prompts work in ChatGPT and Claude?

Yes. They are plain instructions, so they work in any capable assistant. Saving the brief as standing instructions keeps each prompt short.

### How do I stop AI making up facts in my posts?

Tell it never to invent dates, prices, numbers or stories, and to write a placeholder where a real fact is needed. Then check every detail before posting.

### How long should text on a social media image be?

Usually under eight words. The image stops the scroll; the caption carries the detail.
