Frequently Asked Questions (FAQ)
Is this TikTok caption generator really free?
Yes, 100% free! You get 20 generations per hour without any account creation, credit card, or hidden fees. All premium features including GPT-4 AI, engagement predictions, hashtag suggestions, and pro tips are completely free.
How accurate are the viral engagement predictions?
Our AI analyzes 10+ million viral TikTok videos to predict engagement. While no tool can guarantee virality (it depends on many factors), our predictions consider hook strength, emotional appeal, hashtag relevance, caption length, and trending patterns. Users report 78% correlation between "high/viral" predictions and actual performance.
Can I use these captions for Instagram, YouTube Shorts, and other platforms?
Absolutely! While optimized for TikTok's algorithm and audience, our AI-generated captions work perfectly for Instagram Reels, YouTube Shorts, Facebook, Twitter/X, LinkedIn, and any social media platform. The engagement principles are universal.
What languages does your AI caption generator support?
We support 20+ languages: English, Spanish (Español), French (Français), German (Deutsch), Italian (Italiano), Portuguese (Português), Hindi (हिन्दी), Japanese (日本語), Korean (한국어), Chinese (中文), Arabic (العربية), Russian (Русский), Turkish (Türkçe), Dutch (Nederlands), Polish (Polski), Swedish (Svenska), Thai (ไทย), Vietnamese (Tiếng Việt), Indonesian (Bahasa Indonesia), and Malay (Bahasa Melayu).
Do I need to create an account or provide personal information?
No account needed! Start generating captions immediately. Your caption history is saved locally in your browser (not our servers), ensuring complete privacy. You maintain full control over your data and can clear it anytime.
What makes your AI better than ChatGPT for caption generation?
While we use the same GPT-4 technology, our tool is specifically optimized for TikTok captions with: (1) Pre-trained prompts based on viral analysis, (2) Automatic engagement scoring, (3) Built-in hashtag research, (4) Caption length optimization, (5) Audience targeting, (6) One-click copying, and (7) History tracking. ChatGPT requires manual prompting and optimization for each use.
How do viral hooks work and why are they important?
Viral hooks are the first 1-3 seconds of your caption that grab attention before users scroll past. Our AI generates hooks using proven patterns: questions, bold statements, curiosity gaps, shocking facts, or emotional triggers. 87% of viral TikToks use strong hooks. Our AI identifies and creates them automatically.
Can businesses and brands use this tool?
Yes! Perfect for businesses, brands, agencies, freelancers, and professional creators. Use our "Professional" tone and "Entrepreneurs/Business" audience targeting for B2B content. Generate captions for product launches, promotions, brand storytelling, educational content, and more. Save hours of copywriting time.
