Description
WorstGPT is a full-stack AI chatbot platform designed to provide humorous and sarcastic responses instead of traditional polite AI replies. The project explores character-driven AI interaction by creating a chatbot personality that delivers brutally honest and entertaining conversations.
The platform is built with a modern full-stack architecture using React and Vite for the frontend and Node.js with Express for the backend. MongoDB manages user accounts, chat usage tracking, and conversation data while Deepseek V3 API powers the AI responses.
To support scalability and monetization, the platform implements a credit-based freemium system where free users receive limited message credits and premium users gain extended access. Stripe subscription integration manages recurring payments, while webhook events automatically update premium user status.
The application also includes JWT authentication, Google OAuth login, API rate limiting, and a usage tracking system that deducts credits based on token usage. Automated cron jobs reset credits monthly to ensure fair usage across the platform.
