I'll help you set up Supabase tables for all features, create authentication pages, configure Supabase settings, and check the AI functionality issues.

I've implemented a comprehensive Supabase integration for the StudyHub platform, including authentication and database tables. Here's what I've done:

1. Database Schema Setup:

   • Created tables for all features: users, notes, subjects, folders, flashcards, study sessions, exams, study plans, study groups, payments, subscriptions, AI chat history, and resumes
   • Implemented proper relationships between tables with foreign keys
   • Added Row Level Security (RLS) policies to ensure data privacy and security
   • Set up triggers for automatic timestamp updates

2. Authentication System:

   • Created a Supabase client utility for database interactions
   • Implemented an AuthContext provider for managing authentication state
   • Added login and signup pages with proper validation and error handling
   • Created a middleware to protect routes that require authentication
   • Added a ProtectedRoute component for client-side route protection

3. User Profile Management:

   • Created a profile page for users to view and update their information
   • Implemented functionality to update user details in the database
   • Added sign-out functionality

4. Fixed AI Functionality Issues:

   • Updated the OpenAI client to properly use the AI SDK
   • Fixed the API routes for AI Tutor, flashcard generation, and OCR enhancement
   • Added helper functions for generating system prompts
   • Ensured proper error handling and response formatting

5. Package Dependencies:

   • Updated package.json to include all necessary dependencies
   • Added Supabase authentication helpers and client libraries
   • Included AI SDK and OpenAI integration packages

To complete the setup, you'll need to:

1. Configure Supabase in the Vercel Project:

   • Add your Supabase URL and anon key to the environment variables
   • Run the SQL script in your Supabase SQL editor to create all tables and policies

2. Test Authentication Flow:

   • Try signing up a new user
   • Verify email confirmation (if enabled)
   • Test login functionality
   • Update profile information

3. Test AI Functionality:

   • Try the AI Tutor with different subjects
   • Test flashcard generation with sample notes
   • Test OCR enhancement with sample images

The AI functionality should now work correctly with the proper OpenAI SDK integration. If you encounter any issues, check the browser console for specific error messages.

Please make sure to add the following environment variables to your project:
