What is GPT2Skill?

GPT2Skill is a conversion tool designed to connects OpenAI's Custom GPTs and Anthropic's Claude Skills ecosystem. It enables users to transform their existing ChatGPT Custom GPTs, specialise AI assistants built on ChatGPT with custom instructions, knowledge bases, and integrations, into compatible Claude Skills that can run on Claude. This tool is particularly valuable for organizations and developers who have invested in building Custom GPTs but want to use them across multiple AI platforms or migrate to Claude's architecture. By automating the conversion process, GPT2Skill reduces manual reconfiguration time and helps users maximise the value of their AI assistant investments while maintaining consistency across different LLM ecosystems.
