The Social Media Voice Pack

Platform-specific brand voice guidelines and eight copy-paste prompts that keep your AI brand voice intact on LinkedIn, Instagram, X, and TikTok.

The same voice does not mean the same post everywhere. Your LinkedIn self and your TikTok self are the same person at different tables: one is talking shop with peers, one is talking fast to strangers. The personality holds; the delivery shifts. This pack gives you the per-platform settings, the prompts, and the pre-post check, and it builds on the Experience pillar. For a broader set of channels beyond social, see the Channel-Switch Prompt Guide.

Every prompt below has fill-in slots. [CHARTER] means paste your 25-word Voice Charter. [JSON] means paste your Brand Voice JSON if you have one; if not, paste your banned words and two approved phrases.

Per-platform voice settings

LinkedIn

Setting Value
Length 100 to 200 words, short paragraphs, generous line breaks
Opens with A specific scenario, number, or claim. Never "I've been thinking about..."
Formality shift +1 from your baseline, no more
Structure One idea, one small proof, one question or CTA
Never Engagement-bait polls, "Agree?", broetry one-word lines

Instagram

Setting Value
Length Caption under 125 words; first line does the work before "more"
Opens with The most concrete sentence in the piece
Formality shift -2 from baseline, most conversational version of you
Structure Hook line, 2 to 3 short beats, soft CTA
Never Caption essays that restate the image, hashtag walls in the caption body

X

Setting Value
Length One idea per post. Threads only when each post stands alone
Opens with The conclusion, not the setup
Formality shift -2 from baseline, punchiest version of you
Structure Claim, then the one detail that earns it
Never Thread-emoji theatrics, hot takes you wouldn't defend on a call

TikTok (script)

Setting Value
Length 60 to 90 seconds of script, roughly 150 to 220 spoken words
Opens with The payoff promised in the first 2 seconds
Formality shift -3 from baseline, spoken language only, contractions everywhere
Structure Hook, one worked example, one takeaway, verbal CTA
Never Reading a LinkedIn post to camera

The 8 prompts

1. LinkedIn insight post

You write in this voice: [CHARTER]. Follow these rules: [JSON]. Write a LinkedIn post (100-200 words) about [TOPIC]. Open with a specific scenario or number, not a general statement. One idea only. End with a genuine question, not engagement bait. Short paragraphs.

2. LinkedIn story post

Voice: [CHARTER]. Rules: [JSON]. Write a LinkedIn post telling this true story: [3-4 BULLET FACTS OF WHAT HAPPENED]. Keep every fact accurate, add nothing invented. The lesson comes last and stays under two sentences.

3. Instagram caption

Voice: [CHARTER]. Rules: [JSON]. Write an Instagram caption (under 125 words) for a post about [TOPIC]. First line must work standing alone. Conversational, contractions, no hashtags in the body. End with: [YOUR SOFT CTA].

4. X single post

Voice: [CHARTER]. Rules: [JSON]. Write 3 versions of a single X post about [TOPIC]. Lead with the conclusion. One idea each. No threads, no emoji, no hashtags. Rank them by which sounds most like the charter and tell me why.

5. X thread

Voice: [CHARTER]. Rules: [JSON]. Turn this piece into an X thread of 5 posts max: [PASTE CONTENT]. Each post must stand alone. First post states the payoff. No numbering theatrics, no "let me explain."

6. TikTok script

Voice: [CHARTER]. Rules: [JSON]. Write a 75-second TikTok script about [TOPIC]. Spoken language only: read it out loud in your head. First 2 seconds state the payoff. Include one concrete worked example. Mark [PAUSE] where a beat lands. End with: [YOUR VERBAL CTA].

7. Cross-post adapter

Voice: [CHARTER]. Rules: [JSON]. Here is a post that worked on [PLATFORM A]: [PASTE]. Recast it for [PLATFORM B] using these platform rules: [PASTE THE SETTINGS TABLE ROW]. Keep the core idea and my phrasing where it survives the format. Do not summarize; recast.

8. Comment and reply voice

Voice: [CHARTER]. Rules: [JSON]. Draft 3 reply options to this comment: [PASTE COMMENT]. One warm and brief, one that adds a genuinely useful detail, one that politely disagrees. All under 40 words. No "Great point!"

Hook patterns that preserve voice

Hooks go generic before anything else does. These patterns carry a hook without flattening you. Fill the brackets with your specifics.

  • The specific number: "[X] of the last [Y] [things] I reviewed made the same mistake."
  • The scene: "A client asked me [real question] this week. Here's what I told them."
  • The received wisdom, challenged with evidence: "Everyone says [common advice]. I tried it for [timeframe]. Here's what actually happened."
  • The confession: "I got [specific thing] wrong for [timeframe]. The fix took [short time]."
  • The direct address: "If you [specific situation], the next [X words/seconds] will save you [specific cost]."

The pre-post check: does this sound like us?

Thirty seconds before publishing, five questions. Two or more failures, revise before posting.

  1. Read the first line out loud. Would you say it to a person?
  2. Search the draft for your banned words. Any hit fails.
  3. Is there one concrete detail (number, name, scenario)? Zero fails.
  4. Cover the name on the post. Could a follower guess it's you? Honest answer.
  5. Does the CTA match your CTA style, or did the platform's default pushiness leak in?

Log any repeat failure in your prompt library. If question 2 keeps failing, the banned list belongs in the prompt, not just the check.
