Generic prompts give you generic posts. "Write an Instagram caption for a coffee shop" returns the same caption every coffee shop in America already posted. The 20 prompts below are the ones that hold up when you manage real clients: hooks, captions in the client's voice, Reel and TikTok scripts, carousels, comment replies, monthly reports and the conversation about raising your rate. They all depend on one thing first.
The rule that applies to every prompt
Before any prompt, paste a client context block. Keep it in a ChatGPT Project or Claude Project per client so you never retype it:
CLIENT CONTEXT Business: [WHAT THEY SELL, WHERE] Audience: [WHO BUYS, AGE, WHAT THEY CARE ABOUT] Voice: [5 BULLETS: sentence length, humor, words they use, words they never use, how posts end] Never say: [BANNED WORDS, CLAIMS, PRICES IF NOT ALLOWED] This month: [OFFERS, EVENTS, NEWS] Best past captions: [PASTE 3 TO 5]
With that block, ChatGPT for social media stops sounding like a template and starts sounding like the client.
Prompts for hooks and captions
1. Five hooks to choose from
When to use it: you have the post idea but the first line is flat.
Using the client context, write 5 opening lines for a post about [TOPIC]. Each under 12 words, each using a different angle: a surprising fact, a mistake people make, a question, a strong opinion and a specific number. No emojis, no "Did you know".
Tested for a fictional plant shop, topic "overwatering":
1. More houseplants die from love than from neglect.
2. Stop watering on a schedule. Seriously.
3. Is your plant thirsty, or are you just bored?
4. Overwatering is the most common way houseplants die.
5. Two fingers in the soil. That's the whole test.
Number 4 is a claim the AI can't back up, so I'd cut it or soften it. Number 1 is the one I'd post.
2. Caption in the client's voice
Using the client context, write a caption for [POST IDEA]. 60 to 100 words. Start with the hook: [HOOK]. One practical detail (time, place, how to buy). End with a call to action that matches the goal: [SAVE / COMMENT KEYWORD / DM / VISIT]. Don't copy sentences from the past captions.
3. Shorten a long caption
Cut this caption to under 50 words without losing the offer, the date or the call to action. Keep the client's voice. Caption: [PASTE]
4. Three calls to action
Give me 3 calls to action for this post: one to get saves, one to get comments with the keyword [KEYWORD], one to get DMs. Each under 15 words, in the client's voice. Post: [PASTE]
Prompts for Reel and TikTok scripts
5. 30-second Reel script
Write a 30-second Reel script on [TOPIC] for [CLIENT]. Format: scene by scene with seconds, what's on camera, what's said, on-screen text. Hook in the first 2 seconds. 3 points max. Last 3 seconds: [CALL TO ACTION]. The person on camera is [OWNER / EMPLOYEE / NO ONE].
0-2 s: Close-up of a yellowing pothos leaf. Text: "Your plant isn't dying. You're drowning it."
2-10 s: Owner pushes two fingers into the soil. Says: "Before you water, check two inches down. Wet? Walk away."
10-20 s: Pot lifted to show the drainage hole. Says: "No hole at the bottom? That's your problem." Text: "Drainage hole = must"
20-27 s: Side-by-side: soggy soil vs. dry top layer. Says: "Most plants like to dry out a bit between drinks."
27-30 s: Owner holding a pot. Says: "Bring yours in Saturday, we'll check it for free." Text: "Free plant check, Sat 10-2"
Filmable on a phone in 15 minutes, and every scene has a reason. Confirm the Saturday hours with the client; the AI took them from the context block, which is exactly why the block matters.
6. Turn a carousel into a Reel
Turn this carousel into a 20-second Reel script: one scene per slide max, on-screen text under 6 words per scene, voiceover optional. Carousel text: [PASTE]
7. Faceless Reel (text and B-roll only)
Write a faceless 15-second Reel for [CLIENT] about [TOPIC]: 5 on-screen text cards (max 8 words each) and a description of the B-roll clip behind each card. Suggest the music mood, not a specific song.
8. TikTok version of an Instagram post
Rewrite this Instagram post as a TikTok script for [CLIENT]: more casual, faster hook, one idea only, 15 to 25 seconds, caption under 100 characters with 3 relevant hashtags. Post: [PASTE]
Prompts for carousels and planning
9. 7-slide carousel that earns saves
Write a 7-slide carousel on [TOPIC] for [CLIENT]. Slide 1: hook under 8 words. Slides 2-6: one tip per slide, under 25 words each. Slide 7: summary + "Save this for later." Make each tip specific enough that someone could act on it today.
10. Content ideas from customer questions
Here are questions customers asked [CLIENT] this month by DM, phone and in person: [PASTE]. Group them by theme and turn the top 5 themes into post ideas with format and hook.
This is the prompt that gives you ideas no competitor has, because they come from the client's own customers.
11. One idea, four formats
Take this idea: [IDEA]. Give me a Reel hook, a carousel outline (5 slides), a single-image caption and a Story sequence (3 frames with a poll or question sticker). Same message, different format.
12. LinkedIn post for a B2B client
Rewrite this idea as a LinkedIn post from the owner of [CLIENT]: first person, a lesson from the business, under 180 words, no hashtags in the body, no "I'm thrilled to announce." Idea: [PASTE]
Prompts for community and DMs
13. Reply to a negative comment
Write a public reply to this negative comment on [CLIENT]'s post. Calm, no excuses, no arguing, acknowledge the issue, move the conversation to DM or phone [CONTACT]. Under 40 words. Comment: [PASTE]
Tested with: "Bought a fiddle leaf here two weeks ago and it's already dropping leaves. Waste of $60."
Sorry to hear that, and thanks for telling us. Fiddle leafs can drop leaves after a move, but we want to look at yours. Send us a DM or call (512) 555-0142 and we'll sort it out.
It added a plant-care explanation I didn't ask for. Here it helps, but for a restaurant or a clinic, cut anything that sounds like an excuse.
14. Saved replies for the most common DMs
Write saved replies for these 6 recurring DMs for [CLIENT]: [LIST, e.g., "price?", "are you open Sunday?", "do you ship?"]. Each under 40 words, friendly, with the next step (link, booking, phone). Use only facts from the client context; write [ASK CLIENT] where a fact is missing.
Prompts for managing clients
15. Monthly report in owner language
Turn these metrics into a monthly note for a business owner who doesn't know social media terms. Max 150 words: what went well, what didn't, the one business result (DMs, bookings, visits), what changes next month. Use the numbers exactly as given. Metrics: [PASTE]
16. Proposal for a new client
Write a one-page proposal for [BUSINESS] for social media management at $[PRICE]/month: what's included (posts, Reels, Stories, community management hours, report), what's not included (ads budget, photo shoots beyond [N], crisis management), approval process and contract length. Under 300 words, confident, no jargon.
17. Asking for a rate increase without losing the client
Write an email to [CLIENT] raising my rate from $[OLD] to $[NEW] starting [DATE]. Mention 2 results from the last 6 months: [RESULTS]. No apology, appreciative, under 150 words, with an offer to talk on a call.
Hi Rachel, thank you for another great six months working on Green Thumb's social media. A quick look back: Instagram DMs asking about plants went from about 20 a month to 55, and the Saturday plant check we promoted brought in 140 people in September alone. Starting January 1, my monthly rate will be $1,650, up from $1,400. That reflects the added Reels and the DM handling we've built together. Everything else in our agreement stays the same. If you'd like to talk it through, I'm happy to jump on a quick call this week.
Short, anchored in results, no apology. The results line is the only part you must replace with real numbers.
18. Briefing questions for a new client
Write 15 onboarding questions for a new social media client in [INDUSTRY]: goals, customers, offers, what competitors do that they like or hate, banned topics, approval process, access and logins handled by the client, photo availability, past results. Grouped by theme.
Prompts for profiles
19. Instagram bio
Write 3 Instagram bio options for [CLIENT], max 150 characters each: what they do, for whom, where, and one reason to follow. Include the call to action for the link: [LINK GOAL].
20. Quick profile audit
Audit this Instagram profile from the info below: bio, highlights, last 9 posts (format, topic, engagement). Give me the 5 changes with the biggest impact for [GOAL], in order. Info: [PASTE]
Common mistakes with ChatGPT for social media
- Skipping the client context block, then rewriting everything by hand.
- Keeping numbers or claims the client never gave you ("our 1,000 happy customers").
- Asking it for "trending sounds." It doesn't know this week's trends.
- Letting it write reviews or testimonials. That's a problem under the FTC's consumer reviews rule.
- Forgetting the sponsorship disclosure on partner content. The FTC Endorsement Guides apply.
Which AI to use
ChatGPT Plus or Claude Pro, US$ 20 a month each, both handle every prompt here; pick the one whose writing you edit less. Canva for the visuals, CapCut for editing. The full routine with tools and prices is in AI for social media in 2027. When comment-keyword prompts like number 4 start working, automate them: that's the agent that builds the calendar and answers DMs.
Want to skip this part?
Ready-made AI agents for social media managers: nothing to build, no prompts, they already work for you across every client on your roster.
- Build each client's monthly calendar and captions in their voice from the brief
- Reply by DM to whoever comments the keyword and pass the lead to the client
- Turn the month's metrics into a report the business owner understands
Frequently asked questions
What is the best ChatGPT prompt for social media?
The client context block plus the hooks prompt. Without context, every caption sounds generic; with it, five hooks in one minute beat staring at a blank screen.
Can ChatGPT write Instagram captions in a brand voice?
Yes, if you paste 3 to 5 of the client's best captions and a voice description. Save it in a Project per client.
Does ChatGPT know current TikTok and Instagram trends?
No. It only knows its training data. Find the trend yourself and ask the AI to adapt it to the client.
ChatGPT or Claude for social media?
Both handle these prompts well at US$ 20 a month. Test the same prompt in each for a week and keep the one you edit less.
Is it OK to use AI-written captions for clients?
Yes, as long as you review them, keep the facts true and disclose partnerships. Clients pay for strategy and results, not typing.
