What is CustomGPT?

CustomGPT is a no-code platform that allows you to create AI-powered chatbots tailored to your business needs. Built on top of OpenAI’s language models (like GPT-4), it enables users to train the chatbot using their own data, including websites, documents, PDFs, and more. With CustomGPT, you can design an intelligent assistant that understands your content and communicates naturally with users.

Whether you run an eCommerce store, SaaS business, agency, or educational platform, CustomGPT helps you deploy AI bots that answer questions accurately, provide 24/7 support, and improve customer satisfaction.

Top Features of CustomGPT

1. No-Code Chatbot Builder
