Instagram & TikTok Caption Generator with Hook Formulas

How to Use the Instagram & TikTok Caption Generator with Hook Formulas

This prompt generates multiple ready-to-post captions for Instagram and TikTok using proven engagement hook formulas. Each caption is built specifically around your topic, platform, niche, and goal — not recycled templates.

Step 1: Fill in the Required Inputs

You must provide five pieces of information before the prompt will generate captions.

• POST_TOPIC — Describe exactly what your post is about. Be specific and concrete. Instead of workout post, write 10-minute morning workout I do before my kids wake up. Instead of fashion haul, write thrifting trip where I found a vintage Prada bag for $8. Specificity is what sharpens the hooks and makes them feel native to your exact moment.
• PLATFORM — Choose one: Instagram, TikTok, or Both. This determines caption length limits, hook placement, and CTA structure.
• CONTENT_FORMAT — Choose one: Reel/Video, Carousel, Static Image, or TikTok Video. This affects how the hook is positioned and whether a Slide 1 Hook line is generated.
• NICHE — Name your content category: fitness, personal finance, food, mental health, travel, fashion, parenting, beauty, business, wellness, etc. This calibrates vocabulary, audience assumptions, and hook psychology to your specific audience.
• PRIMARY_GOAL — Choose one: Drive Comments, Increase Saves, Boost Shares, Grow Followers, Drive Link-in-Bio Clicks, or Increase Watch Time. Every CTA will be built to serve this exact goal.

Step 2: Add Optional Inputs for Better Personalization

• BRAND_VOICE — If you have a specific tone or comparable creator reference, add it here. Examples: deadpan humor like Matilda Djerf, hype energy like GymShark, or calm authority like Andrew Huberman. If you skip this, the output defaults to conversational and direct.
• INCLUDE_HASHTAGS — Type Yes or No. Defaults to Yes. When enabled, each caption includes 5–10 niche-specific hashtags in a visually separated block below.
• CAPTION_COUNT — Enter how many variations you want, between 1 and 5. Defaults to 3. Each variation uses a completely different hook formula and emotional entry point — never repeated phrasing.

Step 3: Read Your Output

Each caption variation is labeled with its Hook Formula — for example, Curiosity Gap, Pattern Interrupt, Outcome-First, Relatability Punch, Controversial Claim, or Before/After Reveal. This label helps you understand which psychological mechanic triggered engagement, so you can replicate what works over time.

• Instagram: The opening line is optimized to grab attention before the “more” cutoff. The caption body builds context and credibility. The CTA is tailored directly to your primary goal.
• TikTok: The hook is under 10 words and formatted for on-screen text overlays. The caption body is concise. The CTA is designed to trigger comments or shares.
• Both: You receive one caption optimized for Instagram and one for TikTok, each natively structured for its platform.
• Carousels: Each caption variation includes a “Slide 1 Hook” line above the main caption to pull viewers into the first slide.

Step 4: Paste and Post

No editing required. These captions are written to go directly into your post. If something feels off for your voice, adjust your BRAND_VOICE input and run the prompt again — that’s the fastest way to recalibrate tone.

Tips for Best Results

• The more specific your POST_TOPIC, the sharper the hooks. Vague topics produce weaker curiosity gaps and generic CTAs that blend into your feed.
• Rotate your PRIMARY_GOAL between posts. If every caption ends with “drop a comment,” your audience learns to scroll past that CTA. Vary between comments, saves, shares, and follows to keep engagement patterns fresh.
• When posting 5–7 times per week, use CAPTION_COUNT = 4 or 5 to build a buffer of backup captions before your posting window closes. This removes last-minute caption fatigue and keeps your voice consistent across posts.
