I'll help you create a premium SaaS landing page and dashboard for VidGenius AI. This is a comprehensive project, so let me start by generating design inspiration and exploring your codebase structure to build a solid foundation.

I have great design inspiration showing premium dark-mode SaaS aesthetics. Now let me set up a structured plan for building this project:

Now let me start with the first task: setting up the theme and global styles. Let me read the current configuration files:

Now let me create a premium dark theme matching the VidGenius AI brand. I'll update the globals.css with the custom color palette inspired by the design brief:

Now let me update the layout.tsx to apply the dark mode and set proper metadata:

Now let me create the main application page with both the landing page and dashboard. I'll build this as a multi-component system:

Now let me create the Landing Page component. I'll build this with the hero section, features grid, and pricing:

Now let me create the Dashboard component with the sidebar and main workspace:

Now let me move to the next task and verify everything is working:

I've already built the landing page. Let me continue with building the dashboard and move through the remaining tasks:

I've already built the dashboard with sidebar and grid layout. Let me move to the next task:

All interactive components are already integrated into the dashboard. Let me move to the next task:

Page navigation and state management are already implemented in page.tsx and the components. Let me verify the app is working by launching the dev server:

Let me check the dev server output after a moment and verify the application:

The dev server is running and the landing page is rendering correctly. Let me verify the page in the browser to ensure everything is working as expected:

The landing page is rendering beautifully. Let me take a screenshot to verify the visual design and then test the navigation to the dashboard:

Excellent! The landing page looks premium with the dark theme and gradient accents. Now let me click the "Get Started" button to navigate to the dashboard:

The dashboard is loading. Let me take a screenshot to see the full layout and verify all components are visible:

The dashboard is working beautifully with all the components visible. Now let me test the interactive generation feature by filling in some text and clicking generate:

Tested generation flow

The text is filled and the button is enabled. Let me scroll down to see the video preview with the generation progress:

The dashboard is fully responsive and interactive. Now let me test the Logo click to return to the landing page and complete the full navigation cycle:

Let me scroll up on the page to see if we're back at the landing page:

The title indicates we're still on the right page. Let me test the pricing toggle functionality to ensure interactive features work properly:

The pricing section is visible. Now let me click on the yearly button to test the pricing toggle and take a screenshot to verify the state change:

Tested yearly pricing

The landing page is working beautifully with all sections visible. Now let me mark the final task as complete:

Let me create one final verification by checking the responsive design on mobile:

Tested mobile responsiveness

The mobile responsiveness is excellent. Let me close the browser and provide a final summary:

I've successfully built a premium, modern SaaS landing page and AI video generation dashboard for VidGenius AI. Here's what was created:
