The Prompt

Write a social media caption for [PLATFORM].

Post details:
– Platform: [INSTAGRAM, FACEBOOK, LINKEDIN, TWITTER/X, TIKTOK]
– Content type: [PHOTO, VIDEO, CAROUSEL, REEL, STORY]
– Visual description: [WHAT’S IN THE IMAGE/VIDEO]
– Post goal: [ENGAGEMENT, TRAFFIC, SALES, AWARENESS, COMMUNITY BUILDING]

Brand context:
– Who we are: [COMPANY/CREATOR IDENTITY]
– Target audience: [WHO WE’RE TALKING TO]
– Brand voice: [PROFESSIONAL, PLAYFUL, INSPIRATIONAL, EDUCATIONAL, etc.]
– Key message: [MAIN POINT OF THIS POST]

Caption requirements:
– Length: [SHORT (1-2 lines), MEDIUM (3-5 lines), LONG (storytelling)]
– Tone: [CONVERSATIONAL, MOTIVATIONAL, HUMOROUS, AUTHENTIC, etc.]
– Include: [QUESTION, CTA, EMOJI, HASHTAGS]
– Avoid: [OVERLY SALESY, JARGON, CERTAIN TOPICS]

Create a caption that:
1. Hooks attention in the first line
2. Delivers value or entertainment
3. Connects with the visual content
4. Includes a clear call-to-action
5. Uses platform-appropriate formatting

Also suggest:
– 5-10 relevant hashtags (mix of popular and niche)
– Best time to post for maximum engagement

When to Use This Prompt

• You’re staring at a blank screen with no idea what to write
• Your captions aren’t driving the engagement you want
• You need consistent brand voice across multiple platforms
• You’re batch-creating content and need caption variations

What You’ll Get

Writesonic will generate an attention-grabbing opening line that stops scrollers mid-feed, value-driven content that gives readers a reason to engage, seamless connection between caption and visual making the post feel cohesive, platform-specific formatting with line breaks and emojis where appropriate, a compelling call-to-action driving comments, shares, or clicks, strategic hashtag mix balancing reach and relevance, and posting time recommendations based on platform best practices. The caption feels authentic to your brand, not generic AI writing.

Why This Prompt Works

• Visual integration: Describing the image ensures caption and visual work together, not separately

• Goal specificity: Different objectives need different approaches—awareness vs sales require distinct strategies

• Platform awareness: What works on LinkedIn flops on TikTok—platform matters

• Hook emphasis: The first line determines if people read more or scroll past

How to Customize This Prompt

1. [PLATFORM] — Social network: Instagram needs different structure than LinkedIn
2. [CONTENT TYPE] — Format: carousel posts need different captions than single images
3. [VISUAL DESCRIPTION] — What’s shown: “team photo,” “product shot,” “behind-the-scenes”
4. [POST GOAL] — Objective: shapes the CTA and message angle
5. [BRAND IDENTITY] — Who you are: “sustainable fashion brand,” “B2B SaaS,” “fitness coach”
6. [TARGET AUDIENCE] — Who you’re reaching: determines language and references
7. [BRAND VOICE] — Personality: casual vs professional changes everything
8. [LENGTH] — Caption size: short for quick engagement, long for storytelling
9. [TONE] — Feeling: motivational vs humorous require different approaches

Pro Tips

• A/B test variations: Generate 3 different caption styles and test which drives more engagement

• Seasonal adaptation: Add “incorporate [holiday/season]” for timely, relevant content

• Story continuation: Request “write as part of a 3-post series” for campaign consistency

• Engagement boost: Ask “suggest a question that sparks debate in comments” for discussion-driven posts
