@Sean McNeely fair warning, this one's long. Paul already gave you the short version and he's right: if you've got a second brain, point Claude at it and let it cook. If you don't, this is how I'd build one, and I'd rather hand you the actual steps than a tidy paragraph that leaves you nothing to do. Sorry for the wall of text... First, the reason you can't find a good video on this. Most people are asking the wrong question. "How do I move ChatGPT to Claude" has no clean answer. ChatGPT's memory isn't a file you can take with you, it's a summary that lives inside their app, with your rules, your business facts, and years of one-off chats all mashed together. What actually works is: You move ChatGPT into local files you own, in a folder on your own computer not in their software. Then you point Claude, ChatGPT, Grok, or whatever you want to use in the future at the folder. After that you never do this again, because the next tool that comes out just gets pointed at the same folder (You can also store/backup/mirror your second brain in cloud storage like Gsuite, dropbox, etc so you can get access on the go) Here's how I'd do it, in order. STEP 1. GET EVERYTHING OUT OF CHATGPT AND INTO TEXT FILES (about an hour) Make a folder on your desktop called chatgpt-export. Everything below goes in there as a plain text file. Notepad is fine. One file per item, named so you know what it is. Nothing in ChatGPT lives in one place, so work the list: - Saved memories: Settings > Personalization > Manage memories. There's no export button. Select the whole list, paste it into a new text file, save it as memories.txt. Or open a new chat and ask ChatGPT to write out every memory it has about you, word for word, and paste that instead. (Claude's importer hands you an exact prompt for this, more on that below.) - Custom instructions: Settings > Personalization > Custom instructions. Copy both boxes into custom-instructions.txt. - Projects: open each one. Copy the project instructions into a file named for the project, like project-proposals.txt, and re-download any files you uploaded into a subfolder with the same name. Then, inside the project, ask it to summarize everything it knows about that project, the decisions you made, and where you left off. Paste that into the same file. Project instructions are NOT in the data export. Skip this and they're gone.
