Export your memory from Gemini
Gemini keeps a Personal context settings page showing what it's learned about you — view and copy it directly, no prompting required.
Open Personal context settings
In Gemini, click the Settings gear (⚙️) in the bottom-left corner, then open Personal context. You'll see Memory (facts learned from past chats), Your Instructions (standing rules you've given it), and Saved info (things you've explicitly asked it to remember).
Copy what's stored
Copy everything shown across those sections. This becomes your portable profile, ready to paste into another service's import guide.

Google's official help center covers the equivalent import flow at this URL. The Settings → Personal context path for viewing/exporting is confirmed consistently across independent reporting rather than one single official 'how to export' article.
Import memory into ChatGPT
ChatGPT has no dedicated import tool, but its memory feature explicitly saves anything you ask it to remember — so a direct request does the job.
Make sure Memory is turned on
In ChatGPT, go to Settings → Personalization → Memory, and confirm it's enabled.
Paste your profile and ask ChatGPT to remember it
In a new chat, paste this prompt with your memory profile in place of the bracketed instruction.
I'm sharing a structured profile of facts, preferences, and context about me that I'd like you to remember going forward. Please save each distinct item below as its own individual memory — don't collapse them into one summary note, save them separately so each can be recalled on its own. After you've done that, list back exactly what you saved so I can confirm nothing was missed or altered. [paste your memory profile here]
Confirm what was actually saved
Check Settings → Personalization → Memory → Manage memories afterward — that's the real source of truth for what got saved, not just what ChatGPT says back in the chat.
