12 AI Prompts That Turn ChatGPT or Claude Into Your Content Strategist

Copy-paste prompts for social media that go beyond “write me a caption” — strategy, batch ideation, hooks, repurposing and editing, each with the variables that make output sound like you.

Good prompts are briefs, not wishes.

Key takeaways

  • Weak AI output is almost always a weak brief: add audience, voice, format and a quality bar.
  • Give every prompt three ingredients: context (who you are), constraint (format and length), and taste (examples of what you like).
  • Batch prompts (10–30 ideas at once) beat one-at-a-time asks — generate volume, then curate.
  • Ask for tables when you plan to import: theme, hook, caption, visual concept, hashtags.
  • Save your best prompts with your brand variables filled in — that’s your real content team.

“Write me an Instagram caption about coffee” gets you exactly what it deserves. The prompts below get you a strategist, an ideation machine and an editor — because each one carries the three things models actually need: context (who you are, who’s reading), constraints (format, length, platform), and taste (what good looks like to you).

Replace the [BRACKETS], keep what serves you, delete what doesn’t. They work in ChatGPT, Claude, or anything else that reads.

Strategy: make the AI think before it writes

Prompt 1 — The positioning interview
You are a brand strategist. Interview me one question at a time (max 8 questions) to define my content positioning: who I serve, what transformation I offer, what I believe that competitors don’t, and my tone of voice. My business: [WHAT YOU DO]. My audience: [WHO]. At the end, summarize my positioning in 5 lines I can paste above any future prompt.
Prompt 2 — Content pillars from scratch
Based on this positioning: [PASTE 5-LINE SUMMARY]. Propose 4 content pillars for [PLATFORM] following this split: show the work / teach / belong / ask. For each pillar give 3 recurring formats I can repeat weekly without running dry, and name the emotion each format should trigger.

That five-line summary is the highest-leverage artifact in this whole article: paste it at the top of every future chat and the generic-AI flavor disappears. It’s also the natural seed for a 30-day calendar.

Ideation: volume first, taste second

Prompt 3 — The 30-idea table (built for import)
Generate 30 post ideas for [BRAND] on [PLATFORM] for [MONTH/SEASON]. Split them across these pillars: [YOUR PILLARS]. Output a table with columns: # / pillar / hook (first line, max 8 words) / caption draft (60–120 words, tone: [TONE]) / visual concept (one sentence a photographer could shoot from) / 5 hashtags. No emojis unless they earn their place.
Prompt 4 — Hooks only, twenty ways
Here is my post topic: [TOPIC]. Write 20 different opening lines under 10 words each: 5 curiosity-driven, 5 contrarian, 5 specific-number, 5 story-openers. Rank your top 3 and say why they’d stop a scroll.
Prompt 5 — Mine the comments
Here are real comments/DMs from my audience: [PASTE 10–20]. Extract the recurring questions, fears and desires. Turn each into a post idea that answers it without selling, plus one that answers it with a soft pitch for [OFFER].

The table format in Prompt 3 isn’t cosmetic: save the output as Excel or plain text and import the whole batch at once — every row becomes a card on your board. (Connected via MCP? Skip the file — the same ask lands straight in your planner.)

Voice: teach it to sound like you

The model has no taste until you lend it yours.
Prompt 6 — The voice transplant
Here are 3 captions I love: [PASTE]. Here are 2 that make me cringe: [PASTE]. Describe my preferred voice in 6 adjectives + 3 rules (sentence length, punctuation habits, words to avoid). Then rewrite this draft in that voice: [DRAFT].
Prompt 7 — De-AI-ify
Rewrite this caption so it sounds like a busy human wrote it: cut clichés (“game-changer”, “dive in”, “unlock”), no rhetorical-question openers, no “it’s not X, it’s Y” constructions, max one exclamation mark, keep my key point intact: [CAPTION].

Repurposing: one asset, five lives

Prompt 8 — Long-form to feed
Here is my [BLOG POST / VIDEO SCRIPT / NEWSLETTER]: [PASTE]. Extract: 3 standalone tip posts, 2 story-style posts from its examples, 1 carousel outline (7 slides, one idea per slide), and 1 contrarian take it implies but doesn’t say. Table format, with hooks.
Prompt 9 — The resurrection
Here are 5 of my old posts that performed well: [PASTE]. For each, propose a fresh angle for reposting 6 months later: new hook, updated example, opposite framing, or format change (still → Reel, post → carousel). Do not repeat the original wording.

Editing: the last 10% that reads as taste

Prompt 10 — The ruthless editor
Edit this caption: cut it by 30% without losing meaning, replace abstract claims with concrete specifics, and end on a line that invites a reply (not “thoughts?”). Show before/after: [CAPTION].
Prompt 11 — The skeptical reader
Read this post as my most skeptical follower — busy, allergic to marketing. Where do you stop reading and why? What would make you save or share it? Then apply your own fixes: [POST].
Prompt 12 — The CTA matcher
Here’s my post and my current goal ([GROW SAVES / DMs / LINK CLICKS / SALES]). Propose 5 CTAs matched to that goal, from softest to most direct, in my voice: [POST].

Questions, answered

Why do my AI captions all sound the same?
Because the model defaults to its house style when the prompt gives it nothing else. Feed it three examples of captions you love (yours or others’), name the tone you want, and forbid the tics you hate — the output changes immediately.
Should I ask for one caption or many?
Many, then choose. Generation is cheap; taste is your edge. Ask for 10–30 variants in a table, pick the top few, and polish only those. Volume plus fast selection consistently beats careful one-shot generation.
How do I get AI output into my planner without copy-paste?
Two ways: ask for a table and import it as text or Excel in one step, or connect your AI to the planner via MCP so drafts are created directly. Both beat pasting posts one at a time.
