**Most "100 AI prompts" lists are unusable.** They're flat, unsorted, full of generic templates that produce generic AI output. The problem isn't a shortage of prompts. It's that prompts without structure, without brand context, and without the right framework produce content that sounds like every other AI-generated post.

This library is different. **93 AI prompts for social media, organised three ways** — by use case (12 categories), by platform (8 networks), and by which model handles each best. Plus the C-T-F-C framework that turns any prompt into a brand-fit prompt in 30 seconds.

Built for marketers using ChatGPT, Claude, Gemini, or the AI inside [PostEverywhere's content generator](/ai-content-generator). Copy the prompt, plug in your context, ship.

> **Generate captions, hooks, and posts inside the scheduler.** [PostEverywhere's AI content tools](/ai-content-generator) run these prompts natively — no copy-paste between tools. [Start your 7 day free trial →](/pricing)

## How this library is organised

Three ways to navigate, depending on what you're trying to do:

| If you want to... | Jump to |
|---|---|
| Solve a specific marketing job (caption, hook, hashtag, etc.) | [By use case](#by-use-case-12-categories) |
| Optimise for a specific platform | [By platform](#by-platform-instagram-tiktok-linkedin-and-5-more) |
| Pick the right model for the job | [By model](#by-model-which-ai-for-which-task) |
| Make any prompt actually work | [The C-T-F-C framework](#the-c-t-f-c-framework) |

---

## The C-T-F-C framework (use this before every prompt)

The single biggest mistake people make: pasting a generic prompt and expecting brand-fit output. Generic prompt in = generic AI content out. Every prompt below works 10× better when you wrap it in C-T-F-C:

| Layer | What to include |
|---|---|
| **C — Context** | Who you are. What you sell. Your audience. Your brand voice (1-2 examples). |
| **T — Task** | What you want the AI to do. Be specific. |
| **F — Format** | Length, structure, tone, format constraints. |
| **C — Constraints** | What NOT to do. Banned words. Lengths. Things to avoid. |

**Template you can copy:**

```
<context>
I run [TYPE OF BUSINESS] for [AUDIENCE]. Our voice is [3 adjectives].
Brand voice example: "[paste 2-sentence example of your writing]"
</context>

<task>
[The actual prompt from the library below]
</task>

<format>
[Specific format requirements, e.g., "150 chars max, no emojis, ends in question"]
</format>

<constraints>
Avoid: cliches, generic marketing speak, the phrases ["..."], em-dashes for narrative pauses.
Don't include hashtags or links.
</constraints>
```

Claude is specifically trained to parse XML tags like `<context>` and `<constraints>` ([Resonate, 2026](https://www.resonatehq.com/blog/chatgpt-prompts-for-marketing-and-copywriting)), so this format works best for Claude. ChatGPT and Gemini also handle XML tags fine.

## By model: which AI for which task

Based on testing the same prompts across the major 2026 models, here's where each excels for social media work:

| Task | Best model in 2026 | Why |
|---|---|---|
| Long-form captions (LinkedIn, FB) | Claude Opus 4.7 / Sonnet 4.6 | Strongest natural voice, less corporate ([Resonate, 2026](https://www.resonatehq.com/blog/chatgpt-prompts-for-marketing-and-copywriting)) |
| Short hooks (TikTok, Reels, X) | ChatGPT GPT-5.5 | Better at punchy, surprising formulations |
| Hashtag research | Either + WebSearch | Both need real-time data; the WebSearch tool matters more than the model |
| Voice-matching from examples | Claude Opus 4.7 | XML tag handling makes brand voice anchoring more reliable |
| Performance analysis / data interpretation | Gemini 3.1 Pro or Claude Opus 4.7 | Better at structured analytical reasoning |
| Creative ideation (volume) | ChatGPT GPT-5.5 | Higher diversity in 50-prompt generation |
| Creative ideation (depth) | Claude Opus 4.7 | Fewer but more developed ideas |
| Comment moderation drafts | Claude Sonnet 4.6 | Better nuance on tone gradient |
| Repurposing across formats | Claude Opus 4.7 | Better at preserving voice across format shifts |
| Trend analysis with real-time data | Perplexity (any tier) | Native search integration |

The general pattern across 2026: **Claude wins on voice-sensitive work, ChatGPT wins on creative volume, Gemini wins on data interpretation, Perplexity wins when you need real-time research.**

## How to actually use these effectively

Five operational principles that separate brands using AI prompts from brands using them well:

**1. Always wrap in C-T-F-C.** Generic prompt = generic output. Wrap in context + task + format + constraints every time.

**2. Save your three best brand voice examples as a reusable preamble.** Paste them at the top of every prompt session. Claude and ChatGPT both significantly improve voice match when given 2-3 reference examples.

**3. Iterate, don't accept first output.** Treat the first response as a draft. Push back: "make it sharper," "less corporate," "this paragraph doesn't earn its space — cut or replace."

**4. Mix models for different stages.** Use ChatGPT for brainstorming volume, then Claude for the final draft, then either for the polish. Same prompt + different model = different quality result.

**5. Track which prompts work for you and which don't.** Build a personal library. The prompts that work for one brand often need tweaking for another.

## Common mistakes

Five mistakes that turn a well-organised prompt library into mediocre content:

1. **Pasting generic prompts without brand context.** Generic in = generic out. C-T-F-C is non-negotiable.

2. **Accepting the first output.** First drafts from any model are 60-70% there. Push back and iterate.

3. **Using the same prompt for every platform.** The carousel prompt isn't a TikTok prompt. The Twitter prompt isn't a LinkedIn prompt. Platform-shift is real.

4. **Mixing voices across a series.** If you start a series in one voice, every post in that series should match. Test the voice with a 3-post sample before committing.

5. **Using prompts to replace judgment, not augment it.** AI generates options. You pick the right one. That choice is editorial taste, and it doesn't outsource well.

If you're stuck on what to post in the first place, [our content ideation list for TikTok](/blog/100-tiktok-content-ideas) and platform-specific content calendars give you the topic side.

## Frequently asked questions

### What's the best AI for social media content in 2026?

It depends on the task. Claude Opus 4.7 wins on voice-sensitive long-form writing (LinkedIn essays, brand-voice captions). ChatGPT GPT-5.5 wins on creative volume and punchy short-form. Gemini 3.1 Pro wins on data interpretation. Perplexity wins when you need real-time research. Most marketers use 2-3 models for different stages of the workflow.

### How do I make AI-generated social posts not sound like AI?

Three things. First, always use the C-T-F-C framework (context, task, format, constraints) — most "AI tone" comes from missing context. Second, paste 2-3 examples of your actual writing into the prompt so the AI can match your voice. Third, edit the first draft. AI output is rarely publish-ready on the first pass.

### Are these prompts safe to use as-is?

Yes, but they work much better when customised. Every prompt in this library has placeholders like [TOPIC], [AUDIENCE], [NICHE]. Replace them with specifics, and wrap the whole prompt in your C-T-F-C context block. Generic prompt + generic context = generic output.

### Will Google penalise AI-written social posts?

Google doesn't crawl your social posts directly (Twitter aside). What Google penalises is mass AI content on websites without human review or value-add. Social platforms have their own moderation but generally don't penalise AI content — they penalise low engagement, which AI content can be (when generic) or can avoid (when well-edited).

### Which prompts should I save for daily use?

Probably 5-10 from this library, chosen for your specific workflow. Common daily-use prompts: Prompt 1 (Instagram caption), Prompt 11 (topic cluster), Prompt 21 (hashtag set), Prompt 45 (pinned comment), Prompt 58 (long-form to short-form repurposing). Save these in a personal prompt library you reach for every day.

### How do I customise these for my brand voice?

Three steps. First, write a 3-sentence description of your voice (e.g., "Direct, no corporate-speak, one strong claim per paragraph, avoids stale openers"). Second, paste 2-3 examples of your best-performing posts. Third, list 5-10 phrases you'd never write. Put all three in the `<context>` block of every prompt.

### What's the difference between using prompts in ChatGPT vs in PostEverywhere?

ChatGPT (or Claude, Gemini) is a general-purpose AI — great for raw generation, but you copy-paste output into your scheduling tool. PostEverywhere's AI content generator runs prompts natively in the scheduler, with brand voice memory across sessions. The output goes straight to a scheduled post — no copy-paste between tools.

### How often should I update my prompt library?

Quarterly. AI models change, platform features change, your audience changes. Review every 3 months: which prompts are still pulling their weight, which have become stale, what new use cases have emerged. The half-life of a prompt library is shorter than people assume.
