Common Questions
Everything you need to know about CaptionFlow.
How is CaptionFlow different from ChatGPT?
Broad AI knows everything, but it's not a social media expert. CaptionFlow uses specialized prompts engineered for conversion, automatically handles platform-specific formatting, and learns your specific Brand Voice through analysis of your own content.
How does the voice training work?
You upload 3-5 of your best past captions. Our AI decomposes your sentence structure, vocabulary preferences, and emotional tone. It then applies this 'DNA' to every new caption it generates for you.
Can I really use it for LinkedIn and X too?
Yes! We support the four pillars: Instagram, TikTok, LinkedIn, and X (Twitter). The AI adapts the style for each—professional and insight-driven for LinkedIn, punchy and thread-ready for X.
What happens when I hit my daily free limit?
Free users get 10 high-quality generations every 24 hours. If you're a heavy creator, our Pro plan offers unlimited generations and advanced voice training tools.
