What is Custom GPT

Custom GPT is OpenAI's GPT Builder tool designed for businesses, sales teams, and professionals who want to create specialized AI assistants without engineering resources. It provides no-code interface for building GPTs with custom instructions, knowledge base upload adding company documents and data, conversation starters guiding user interactions, capabilities selection (web browsing, DALL-E, code interpreter), and sharing options publishing GPTs privately or publicly. People use Custom GPT because it democratizes AI assistant creation, enables domain-specific AI trained on proprietary knowledge, and costs just $20/month (ChatGPT Plus subscription) instead of thousands for custom development.

Custom GPT shines in sales teams creating product knowledge assistants, content teams building brand voice generators, research teams developing data analysis tools, and organizations wanting internal AI assistants. Teams see results fast, often building functional GPT in 15-30 minutes and saving 5-10 hours per week on repetitive tasks through automation. It fits smoothly into your tech stack as standalone AI assistant accessible via ChatGPT web/mobile, with potential Zapier integration for workflows. Custom GPT is not designed for complex enterprise AI requiring APIs but focuses on accessible custom AI creation efficiently.
