Instagram & Visual Captions
Instagram captions live or die by the first line. These four prompts cover the most common posting scenarios — from product launches to everyday storytelling — and each one is built to stop the scroll.
Hook Caption
InstagramWrite 5 Instagram caption variations for a photo of [describe photo]. Tone: [casual/professional/funny]. Include a relevant call-to-action and 3 hashtag suggestions. Keep each under 150 characters.
Tip: Works best when you describe the emotion or story behind the photo, not just what's in it.
Product Launch Caption
InstagramI'm launching [product/service]. Write an Instagram caption that builds curiosity without giving everything away. Use a hook in the first line. End with a CTA to click the link in bio.
Tip: The first line shows before "more" — make it a scroll-stopper.
Storytelling Caption
InstagramTurn this rough idea into a polished Instagram caption with a storytelling arc: [your rough idea]. Keep it conversational, under 300 words, and end with a reflective question to drive comments.
Tip: Questions at the end dramatically increase comment rates.
Carousel Post Script
InstagramCreate a 7-slide carousel outline for Instagram about [topic]. Give each slide a title and 1-2 bullet points. Slide 1 should be a bold hook. Slide 7 should be a CTA.
Tip: The hook slide (slide 1) and last slide (CTA) are the two most important.
LinkedIn & Professional Content
LinkedIn rewards directness and strong opinions. These four prompts are built around what actually performs — hook-first openings, contrarian takes, and engagement-driving questions.
LinkedIn Post Hook
LinkedInWrite 5 opening lines for a LinkedIn post about [topic or lesson learned]. Each should stop the scroll — no "I'm excited to share" openings. Make them direct, specific, or counterintuitive.
Tip: LinkedIn's algorithm shows only the first 2 lines before the "see more" cutoff — your hook is everything.
Thought Leadership Post
LinkedInI believe [contrarian or strong opinion about your industry]. Write a LinkedIn post making this argument. Use a personal story or specific data point to open. Keep it under 250 words.
Tip: Contrarian opinions outperform agreeable ones by 3x on LinkedIn.
Newsletter/Content Teaser
LinkedInI published [article/newsletter/product] about [topic]. Write a LinkedIn post that teases 3 key takeaways and drives people to click the link. Use line breaks for readability.
Tip: Short paragraphs (1-2 sentences each) perform far better than walls of text.
Connection/Engagement Post
LinkedInWrite a LinkedIn post asking my network a question about [industry topic]. Make it specific enough to get smart answers, but broad enough that many people can weigh in.
Tip: Questions that make people reflect on their own experience drive the highest engagement.
Twitter/X Threads
Twitter/X threads are one of the highest-leverage content formats — one great thread can get thousands of impressions. These four prompts cover everything from writing the opener to building a full 7-tweet outline.
Thread Opener
Twitter/XWrite the first tweet of a Twitter thread about [topic]. It must be strong enough to stand alone as a tweet AND make people want to read the rest. Under 280 characters.
Tip: Your thread opener is your ad. If it doesn't hook, nobody clicks.
Full Thread Outline
Twitter/XWrite a 7-tweet thread about [topic]. Tweet 1 is the hook. Tweets 2-6 each cover one key point with a specific example or stat. Tweet 7 is a summary + CTA. Keep each under 280 characters.
Tip: Number your tweets (1/, 2/, etc.) — it signals there's more and increases thread click-through.
Quote Tweet Response
Twitter/XI want to share my perspective on this tweet: "[paste the tweet]". Write a quote tweet response that adds genuine value, establishes my POV, and sparks replies. Keep it under 240 characters.
Tip: Adding value to viral tweets is one of the fastest ways to grow an engaged following.
Weekly Value Tweet
Twitter/XWrite 5 standalone tweets sharing a tip, insight, or quick win for [your audience]. Each should be useful on its own — no context needed. Under 240 characters each.
Tip: "Tweetable tips" are the most saved and retweeted format.
TikTok & Reels Hooks
Short-form video is the highest-reach format on social media right now — but the first 3 seconds decide everything. These four prompts help you nail the hook, script the video, and make content that earns shares.
Hook Script (First 3 Seconds)
TikTokWrite 10 hook variations for a TikTok/Reel about [topic]. Each must grab attention in the first 2-3 seconds. Mix question hooks, bold statement hooks, and "POV" hooks.
Tip: TikTok's algorithm decides within 3 seconds whether to boost your video — the hook is everything.
Video Script
TikTokWrite a 45-second TikTok script about [topic] for [target audience]. Structure: hook (3s) → problem (10s) → solution or insight (25s) → CTA (7s). Conversational tone, no jargon.
Tip: The "45-second sweet spot" gets full watch time, which signals quality to the algorithm.
Trending Sound Caption
TikTokI'm using a trending audio for a TikTok about [topic]. Write 5 on-screen text options that sync with the "build-up and drop" structure of trending sounds. Keep each under 8 words per frame.
Tip: On-screen text that matches the audio beat pattern gets 2-3x more shares.
Educational Carousel (Reel)
TikTokScript a 60-second Instagram Reel teaching [skill/tip] using a "did you know?" format. Include a punchy hook, 3 surprising facts with short explanations, and end with a recommendation to follow for more.
Tip: Educational Reels have the longest shelf life — they keep getting served for weeks.
