You will get ChatGPT & OpenAI Integration for React / Next.js | NestJS Backend
Project details
Want to add AI to your React or Next.js app? I'll integrate ChatGPT or OpenAI — your users type a question, your app gives a smart answer. Fully secure, production-ready, and built into your existing codebase.
✅ What you get:
• A working AI chat your users can actually use
• Secure backend (NestJS / Next.js API route — API key never exposed)
• Upload documents and ask AI questions about them (RAG)
• AI that remembers the conversation context
• Clean React UI with real-time streaming responses
• Source code + setup guide included
⚡ Real results from production:
• 40% better search accuracy using AI embeddings
• 8+ apps shipped — 50,000+ active users
• 30+ client projects delivered with 5-star satisfaction
🛠 Stack: React · Next.js · NestJS · FastAPI · OpenAI · LangChain · PostgreSQL · Supabase
📋 How it works:
1. You share your app — I review and confirm exactly what gets built
2. I build the AI backend + React UI with a progress update midway
3. Review call before delivery — nothing ships until you approve
4. Full handover
🎯 Perfect for: SaaS apps · AI chatbots · Document search · Customer support tools
Message me before ordering — I'll confirm scope at no cost.
