What moves, step by step.
01
Export your ChatGPT data
In ChatGPT, go to Settings > Data Controls > Export Data. OpenAI emails you a zip with a conversations.json holding your full chat history. Keep it: it is your archive, whatever you switch to. Want it readable? Our free ChatGPT to Markdown converter turns it into clean markdown files.
02
Carry your context over by hand
Grok keeps its own memory but has no import from other AIs today. The manual route: ask ChatGPT to write out what it knows about you and paste the pieces you want into Grok. It works, but it is a one-time snapshot you will be redoing every time something changes.
03
Keep the part that matters: a living memory
Bring your ChatGPT history into MemoryPlugin in a few clicks, no scripts. And that first import is the last manual step: from then on, your new conversations keep syncing into the same archive on their own, Grok and ChatGPT alike. From your next conversation, Grok can draw on everything you have already discussed, and so can every other AI you use. Your context stops living inside one vendor's app.
The part no import can carry.
An export file is not a memory. The native imports are worth using, and they hand Grok a snapshot of what ChatGPT knew on the day you left. Snapshots age: your projects move on, your preferences shift, and the pasted summary stays frozen.
MemoryPlugin is the layer above the switch: your full chat history, synced automatically and searchable from inside Grok, and one memory that keeps growing with you, in whichever AI you open. A memory that gets better with age, not worse. And if you end up using ChatGPT and Grok side by side, like most people do, they finally share one brain, and one archive that stays current on both sides.
