Switch from ChatGPT to Claude without losing your data. Here's the 4-step process. Step 1: Use Claude's memory import tool at claude.com/import-memory. It pulls your ChatGPT context over in minutes. Step 2: Ask ChatGPT to write a detailed biography of everything it knows about you. Have it ask clarifying questions. Edit the result, then paste it into Claude's memory. Step 3: Move your custom GPTs into Claude projects. Copy the instructions, upload the files. Step 4: Export your ChatGPT data as backup. But don't dump it all into Claude... most of it's noise. Honest warning: Claude's website isn't as polished as ChatGPT's. But if you learn Claude Code, it's a 10x upgrade.
