How to transfer ChatGPT memory to Claude (with Kortex) # How to transfer ChatGPT memory to Claude (with Kortex) 5 minutes 6 steps Updated November 10, 2026 ## Quick answer Kortex does not import ChatGPT's built-in memory. It keeps your own facts in Kortex Memory instead. Add the facts you want, then type ;me in Claude or Gemini. Kortex puts them in your message as an about-me pack that you read and edit first. ## Watch it first How to move context between ChatGPT, Claude and Gemini with ;ref, ;pack and ;me (Kortex) Read the transcript Kortex, for Gemini Notebook, formerly NotebookLM, keeps your AI chats on your computer. Here's how to carry what they know into any other AI. In any AI's chat box, type a semicolon. A menu opens with your saved prompts and Kortex's commands. Semicolon ref lists your past chats from any AI, the closest to your draft first. Pick one, and the part that matters goes in, with a link back. Semicolon pack turns a folder into a project brief: what its chats decided, plus your pins and notes. Semicolon me adds an about-me pack from your Memory. You read and edit every pack before it goes in. To move a whole chat, open its menu and choose Continue in another AI. Pick the AI, check the pack, and Kortex opens a new chat there with it. Memory holds facts about you that you approve. Select a sentence in an answer and click Remember. If it's close to a fact you have, choose Update it or Keep both. When a fact stops being true, open its menu and choose No longer true. Kortex keeps it with an end date, and stops using it. Start every new chat with what you already worked out. ## What you need - The [Kortex extension](https://chromewebstore.google.com/detail/kortex/hdapplggdhndkblofffknpmnnnnbncbn) in Chrome, Edge or Brave, and signed in - Saving turned on: you clicked Keep my chats in my Library when Kortex asked - The facts about you that you want Claude to know, in your head or in your ChatGPT memory list ## On this page 1.

[Ask us](#contact). ### Can Kortex import ChatGPT's memory into Claude? No. Kortex does not read ChatGPT's built-in memory. You keep your own facts in Kortex Memory, and ;me adds them to Claude, Gemini or any AI's chat box. ### Do my facts leave my computer? Memory is stored on your computer. A fact leaves only when you send it, for example in an about-me pack you add to a message. You read and edit the pack first. ### Does ;me work in ChatGPT too? Yes. The ; menu, with ;me, works in the chat box of every AI site Kortex supports. So one set of facts serves ChatGPT, Claude, Gemini and the rest. ### What if a fact changes? Mark it No longer true. Kortex keeps it with an end date instead of deleting it, and does not use it any more. True again undoes that. ## Keep going [Chat Library Keep your AI chats on your computer and search them, next to your YouTube videos and notebooks.](/features#organize) [Kortex docs The full reference for this feature, with every option.](/docs/chat-library) ### More tutorials - [How to move a ChatGPT conversation to Claude](/tutorials/how-to-move-chatgpt-conversations-to-claude) - [How to reference another chat in ChatGPT](/tutorials/how-to-reference-old-chats-in-chatgpt) - [How to switch from ChatGPT to Claude: what to bring over](/tutorials/how-to-switch-from-chatgpt-to-claude) - [How to add notes to ChatGPT conversations](/tutorials/how-to-add-notes-to-chatgpt-conversations) [All tutorials](/tutorials) ## Do it on your own notebooks.
