There is no official way to move ChatGPT memory into Claude as of 2026-08-27, because neither company wants your context to travel. There are two real paths: the manual paste, which works today and goes stale tomorrow, and a portable file that was built to move.
In ChatGPT, ask: "Write a compact profile of me from your memory: how I work, what I am working on, how I like answers." Copy the result. In Claude, open a Project and paste it into the project instructions, or simply make it your first message. Claude will meet you warmer immediately. The catch is that you will be doing this again next month, and neither copy updates the other.
Memory is the strongest retention feature an AI product has. The more an assistant knows you, the more it costs you to leave, so no lab has an incentive to ship an export that works. Waiting for ChatGPT and Claude to interoperate on your profile means waiting for both to volunteer to make leaving easier. That is not coming.
A Pupul profile inverts the ownership. You keep one record of who you are and how to meet you, held outside every assistant, and you hand that same record to ChatGPT, Claude, and whatever ships next. You write every line, each AI gets exactly the slice you scope in, and revoking ends every grant at once. The record is yours, so the question of transferring between companies stops mattering.
ChatGPT hands you that export in minutes. The free ChatGPT Count opens it in this browser and prints what is actually in it: how many conversations, how many messages, and the span of time they cover. It counts, and it shows you the shape of the file. No account, no email field, and the file never leaves your device.

Within a Project, the instructions you paste persist for every chat in that project. Claude also has its own memory features, but like ChatGPT, what it learns stays inside Claude.
Only paste what you would be comfortable with each provider storing. A Pupul profile helps here because you scope exactly which lines travel, and the sensitive layer never leaves you at all.
