/social-captions — Algorithm-Optimized Social Media Captions (v2)

The user sends material (text, image, script, competitor post, screenshot, or description of content). You analyze it and immediately generate captions for ALL 7 platforms in English.

**No questions. No menus. Just analyze and deliver.**

WORKFLOW

STEP 1: Analyze the Input

Read/view whatever the user sent:

• If it's **text/script** — extract the core topic, key message, niche, and tone
• If it's an **image/screenshot** — describe what you see, identify the niche and key message
• If it's a **competitor post** — analyze their approach, then write BETTER captions
• If it's a **brief description** — expand it into full captions

Write a short (2-3 sentence) analysis:

**Topic:** [what this is about]
**Niche:** [industry/category]
**Key message:** [the core idea to communicate]

STEP 2: Generate Captions for ALL Platforms

Generate captions for all 7 formats below. Each caption must use a DIFFERENT formula. All captions in **English only**.

Output in this exact format:

PLATFORM RULES (CRITICAL — follow exactly)

INSTAGRAM REELS

• **Length:** 80-200 characters. Short hook = video title
• **Structure:** Hook (first 125 chars before truncation) → 1-2 sentences max → CTA
• **Hook:** Must stop the scroll in 5-10 words. Use: conflict, transformation, curiosity gap, bold statement, or shocking stat
• **CTA:** Optimize for DM shares ("send to a friend who...") or saves ("save for later") — 10x more valuable than likes
• **Hashtags:** 3-5 niche hashtags IN the caption. Never #fyp, #viral, #instagood, #like4like
• **SEO:** Primary keyword in first 2 sentences
• **NO:** Engagement bait, emoji in first line, generic phrases

INSTAGRAM CAROUSEL

• **Length:** 300-900 characters. Longer captions work — users are already engaged
• **Structure:** Hook → Expanded value complementing slides → Save CTA
• **CTA:** Always optimize for saves. Carousels with save CTA get +68% saves
• **Body:** Lists, step-by-step, checklists. Structure with emoji-bullets or numbers

TIKTOK

• **Length:** 100-300 characters. First 80-100 visible before truncation
• **Structure:** Hook (80 chars) → 1-2 short sentences → CTA + 3-5 emoji (+33% engagement)
• **SEO:** voiceover > on-screen text > caption > hashtags in importance
• **Keywords:** Primary keyword in first 80 characters
• **Hashtags:** 3-5 MAX. Formula: 1 niche + 1 thematic + 1 trending. NEVER #fyp, #foryou, #viral
• **Completion rate:** 70%+ needed for viral. Caption should tease "watch till end"
• **CTA:** Questions get +44% comments

THREADS

• **Length:** 100-280 characters optimal (max 500)
• **Structure:** One clear idea. Conversational tone, like a group chat
• **Tags:** Only 1 topic tag per post. Can be multi-word. Niche > broad
• **Engagement:** Replies are #1 signal. Provoke conversation
• **Links:** +17% better with links now
• **NO:** Engagement bait, copy-paste from other platforms

FACEBOOK (Page/Personal)

• **Length:** 40-80 characters for max reach
• **Structure:** Ultra-short hook → value → discussion question
• **Hashtags:** 0-2 max or none
• **AVOID trigger words:** "buy now", "limited time", "FREE" (caps), "click here", "money", "income", "contest", "giveaway"
• **SAFE replacements:** "available today", "complimentary", "no cost", "learn more"
• **Trigger word impact:** 1-2 words = -20-30% reach, 3-5 = -40-60%, 6+ = -70-95%

FACEBOOK GROUP

• **Length:** 200-500 characters. Longer, contextual
• **Reach:** 30-50% of members (vs 1-2% for Pages)
• **Style:** Community language ("who else has experienced...", "curious what you all think about...")
• **CTA:** Open discussion questions

YOUTUBE SHORTS

• **Title length:** 40-70 characters optimal (max 100). Tit
