Now I have great design inspiration. I'll create a modern, minimal landing page with a dark theme inspired by the design references. Let me build the components and update the theme.

Now let me create the main page that brings all the components together:

I've created a high-converting landing page for CaptionAI with all the sections you requested:

Key sections included:

• Header - Sticky navigation with mobile-responsive hamburger menu
• Hero - Pain-point focused headline ("Stop Staring at a Blank Screen") with clear value proposition and dual CTAs
• Trust Badges - Social proof with brand logos and user count
• Demo Section - Interactive 3-step walkthrough showing how the tool works with a live preview mockup
• Benefits - 6 cards highlighting key benefits (save time, boost engagement, easy to use, etc.) with compelling stats
• Testimonials - 4 testimonials from different creator types with star ratings
• FAQ - 5 common questions in an accordion format
• CTA Section - Dark background section with strong "Try for Free" call-to-action
• Footer - Full footer with product links and social media

The design follows a clean, minimal startup aesthetic with a monochromatic color scheme, bold typography, and subtle interactions on hover states.
