Let me read the reference examples to understand the patterns, then build the AI features:

Now I have a good understanding of the patterns. Let me create the AI API routes and components. I'll build:

1. API routes for AI features
2. AI Assistant panel component
3. AI Insights dashboard page
4. Integrate AI into the invoice form

Now let me create the AI Assistant panel component:

Now let me create the AI Insights dashboard page:

Now let me update the Create Invoice page to include the AI Assistant panel:

Now let me update the sidebar to add the AI Insights link and update the header component to accept children:

Now let me create an AI-powered quick actions component for the dashboard and add AI features to the dashboard page:

Now update the dashboard page to include the AI Quick Insights:

Now let me create AI-powered features for the invoice form - a dedicated component that provides inline AI suggestions:

Now let me update the invoice form to include AI suggestions:

Let me verify the app is working by checking the console logs:

I need to install the AI SDK packages:

Now let me verify the app is working:

The dashboard looks great with the sidebar navigation and AI Insights highlighted with a "NEW" badge. Let me scroll down to see the AI Quick Insights section:

I can see the "AI Quick Insights" panel on the right showing "Live" status, "Powered by GPT-4", and a "Revenue Forecast" of $24,500 with +18%. Let me navigate to the AI Insights page:

The AI Insights page looks excellent with a Business Health Score of 87 (Good), financial metrics showing $21.3k Collected, $16.4k Pending, $2.1k Overdue, and 17d Avg Payment. The insights include "Strong Payment Velocity" and "Overdue Invoice Alert" with priority badges. Let me check the Create Invoice page with the AI assistant:

Took screenshot

The Create Invoice page is working with:

• A "Hide AI" toggle in the header
• An "AI Suggest" button next to Line Items
• Real-time invoice preview
• The AI Assistant panel on the right (partially visible with "Chat" tab visible)

Let me scroll right to see the full AI Assistant panel:

Excellent! The full layout now shows:

• Invoice Form on the left with Customer Info, Invoice Details, Line Items (with AI Suggest button), and Tax Settings
• Invoice Preview in the middle with a real-time rendered invoice

• AI Assistant on the right with:

  • "Smart" badge
  • "Powered by GPT-4"
  • "Chat" and "Quick Actions" tabs
  • "How can I help?" prompt
  • "Ask me anything..." input field

Let me verify the Recommendations tab on the AI Insights page:

Took screenshot

The Recommendations tab looks excellent with actionable AI-powered suggestions including:

1. Implement Early Payment Discount (low effort) - "+$4,200/month"
2. Automate Payment Reminders (low effort) - "-40% late payments"
3. Diversify Client Portfolio (high effort) - "Risk reduction"
4. Increase Retainer Offerings (medium effort) - "+$8,500/month"
5. Optimize Invoice Timing (low effort) - Send invoices on Tuesdays at 10 AM

Let me check the Forecasts tab:

The Forecasts tab is beautifully designed with:

• Revenue Forecast chart showing actual vs AI-projected revenue from Jan to Jun
• Payment Risk Distribution pie chart showing Low Risk (65%), Medium Risk (25%), High Risk (10%)
• Monthly Cash Flow Projection at the bottom

The application is fully functional with comprehensive AI features. Let me provide a summary of what was built:

I've already implemented all the AI features you requested. Let me verify everything is working correctly by checking for any errors:

I see the AI SDK packages didn't install properly. Let me reinstall them:

It says "Already up to date", but there's an issue. Let me check the package.json:

The packages are in package.json. The issue might be a pnpm cache issue. Let me reinstall with force:

Packages are reinstalled. Now let me verify the app is working:
