What moves, step by step.
01
Export your Claude data
In Claude (web or desktop), click your initials > Settings > Privacy > Export data. Anthropic emails a download link (it expires after 24 hours) with your conversations as JSON. Keep it: it is your archive, whatever you switch to. Want it readable? Our free Claude to Markdown converter turns it into clean markdown files.
02
Carry your context over by hand
ChatGPT has no native way to import memory or history from Claude. The manual route: ask Claude to write out what it knows about you, then paste the parts you want into ChatGPT and tell it to remember them. 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 Claude 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, ChatGPT and Claude alike. From your next conversation, ChatGPT 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 ChatGPT a snapshot of what Claude 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 ChatGPT, 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 Claude and ChatGPT side by side, like most people do, they finally share one brain, and one archive that stays current on both sides.
