Convert Custom GPTs to Claude Skills

About

GPT2Skill converts your ChatGPT Custom GPT configurations into ready-to-use Claude Skills. Paste your GPT's name, description, instructions, and conversation starters. Upload your knowledge files. Download a ZIP and upload it to claude.ai/customize/skills. Done. I built this because I wanted to move my Custom GPTs to Claude but didn't want to manually reformat everything. It's a single HTML file — no build system, no framework, no npm. Just open it in a browser or visit gpt2skill.com.
