GPT Trainer is a web-based tool that enables users to fine-tune GPT models using plain language and data file uploads�no coding required. It�s designed to let individuals and teams train their own AI by simply chatting with the model, defining behavior, and uploading documents, CSVs, or PDFs.
The platform streamlines the traditionally complex process of GPT fine-tuning into a user-friendly flow: upload, train, and deploy. You can build a custom chatbot, knowledge base assistant, or even a brand voice replicator�all without diving into APIs or ML frameworks. GPT Trainer is particularly suited for educators, marketers, HR teams, and support teams looking to create niche-specific AI solutions. In short, it�s a do-it-yourself platform for making GPT models smarter, faster, and more personalized.
