93 AI Prompts for Social Media: The 2026 Library (ChatGPT, Claude, Gemini)

Last updated: May 2026.

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. Copy the prompt, plug in your context, ship.

Generate captions, hooks, and posts inside the scheduler. PostEverywhere's AI content tools run these prompts natively — no copy-paste between tools. Start your 7 day free trial →

How this library is organised

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

---

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:

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), 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:

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.

For more on choosing between models, see our model comparison for social marketers.

Use these prompts inside PostEverywhere's content tools. The AI content generator runs prompt-driven generation natively in the scheduler — no copy-paste between ChatGPT and your scheduling tool. See pricing →

---

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 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.
