Map your ecosystem

Moving from ChatGPT to Claude does not mean starting again.

You do not need the old chats, you need what ChatGPT has learnt about you from them, how you like things written, the work you do and the people in it.

The longer you leave it, the more it knows about you and the bigger the move gets, so if it is what has been stopping you, it is worth doing now.

This prompt gets it out, and it is built on the one Anthropic, who make Claude, publish for this.

Paste it into a new chat in ChatGPT and it writes out everything it remembers about you in one block you can copy.

Then run it a second time, because it will not always get everything first time.

In another new chat, paste this with the first list where the capitals are, and it gives you only what it missed.

Note: Read the list before it goes anywhere and take out client names and anything else you would rather not move, because nothing goes across except the text you paste.

In the Claude app, it goes into Claude's memory.

Go to Settings, then Memory, choose Start import, paste the list in and choose Add to memory.

Note: Anthropic call the import experimental and say it keeps mostly what is about your work, so open Memory again afterwards and read what it kept.

In your ecosystem, it goes into your briefs and files, and only once you have agreed what.

Open Claude Code in the folder and paste this with the list after it, and it compares the two, tells you what it would update and what it would leave out, and changes nothing until you say go ahead.
