The short answer
The best AI prompts for social media give the model a voice guide, a real detail and a job for each post. These 14 prompts cover planning, LinkedIn and Instagram posts, short video scripts, repurposing, graphics, comment replies and analytics. Claude is the strongest writer for posts in your voice, Perplexity finds current topics with sources, and Canva or Ideogram handle graphics with readable text. Always edit before you publish.

How to get social posts from AI that sound like you
Most AI social posts fail for the same reason: the prompt gives the model nothing specific, so it writes the average of every post it has seen. The fix is to feed it three things it cannot invent. First, a voice guide built from your own best posts (prompt 4 makes one). Second, a real detail: a number, a customer story, a mistake you made. Third, a job for the post, such as "get saves" or "get sign-ups for the webinar on [date]". The 14 prompts below are grouped by the job they do: planning, writing, repurposing, visuals and community.
One rule before you start: AI drafts, you publish. Read every post aloud, check every number and remove anything you would not say in person. Readers spot generic AI phrasing quickly, and a post that sounds like a template costs you more trust than it saves in time.
Prompts to plan your social media content
The pillar prompt and the calendar prompt work in any chat assistant. The pillar prompt asks for one metric per pillar on purpose: without it, you will not know after a month which pillar to drop. For "Find this month's conversations", use a tool that searches the web and shows sources, then open the sources. Perplexity lists numbered sources under every answer, which makes it the quickest option, and it lets you check the date of each source rather than trusting the model's sense of what is current.
Prompts to write posts for LinkedIn, Instagram and short video
Run the voice guide prompt once, save the result and paste it into every writing prompt. It is the single biggest improvement you can make. The LinkedIn prompt bans an opening question and asks for three alternative first lines, because the first line decides whether anyone clicks "see more". The carousel prompt limits words per slide because carousels are read on a phone. The video script prompt gives you three hooks so you can film all three and keep the one that holds attention. For more LinkedIn-specific prompts, see prompts for LinkedIn posts.
Prompts to repurpose one piece of content everywhere
Repurposing is where AI pays for itself. The article prompt insists that each piece uses a different point, which stops you posting the same idea six times. The clip prompt works on any transcript; if you edit in Descript, you can cut the clips by editing the transcript text, and its Underlord co-editor can make clips and captions for you. The platform prompt asks the model to explain each change, so you learn the conventions instead of copying them blindly.
Prompts for social media visuals
For graphics with words on them, use a tool that is good at text. Ideogram's docs say to put the exact words in quotation marks and say where they sit, and its Studio text layers let you fix the wording afterwards. The catch: on Ideogram's free plan every image is public. Canva suits teams that keep a brand kit there: Magic Resize turns one design into every format, and on paid plans the Standard AI tools such as Magic Write, Magic Resize and Translate do not use the shared AI allowance (Pro Lite is the exception). For photographic or illustrated campaign images, Midjourney keeps a set consistent with style references; our Midjourney prompts page has templates with the right parameters, such as --ar 4:5 for feed posts and --ar 9:16 for stories.
Prompts to manage comments and learn from your numbers
The reply prompt flags complaints, legal or safety issues and press enquiries for a person, because those are the replies that go wrong when automated. The analytics prompt ranks posts per impression rather than by raw likes, which removes the effect of a post simply being shown to more people, and it asks the model to admit when the sample is too small. Upload the export as a file: ChatGPT is strong at spreadsheet and file analysis, and Claude can also run code on uploaded files. Spot-check two or three rows of the result against the original export.
Which AI tool works best for social media
| Job | Best tool | Why |
|---|---|---|
| Writing posts in your voice | Claude | Careful writing and editing, and it follows a long voice guide well |
| Trend and topic research | Perplexity | Numbered sources under every answer |
| Analytics exports | ChatGPT | Spreadsheet and file analysis |
| Graphics with text | Ideogram | Readable text in images; free plan images are public |
| On-brand designs in many sizes | Canva | Brand kits, Magic Resize and Translate |
| Clips from long video | Descript | Edit video by editing the transcript |
Pick Claude if your biggest problem is posts that sound generic. Pick ChatGPT if you want one assistant that also handles your spreadsheets and images. Canva AI 2.0, which Canva launched as a research preview on 16 April 2026, adds conversational design and scheduled tasks such as a weekly batch of social posts, but it is still rolling out, so check what your plan shows. Compare more options in the best AI for social media and the best AI for marketing.
How to adapt these social media prompts
- Replace every bracket with a real detail. "Cut onboarding calls from 45 to 20 minutes" beats "improved efficiency".
- Keep the limits. Word counts, "no emojis" and "never two promotional posts in a row" are what make the output usable. Change the numbers, keep the rules.
- Save your voice guide as a reusable instruction. Put it in a ChatGPT or Claude project, or a Gemini skill, so you do not have to paste it each time.
- Ask for options, then choose. Three first lines, three hooks: the choice is where your judgement adds value.
- Protect client and customer data. Remove names from comments and exports, or turn off training first: in ChatGPT under Settings, Data controls; in Claude under Settings, Privacy.
