Switching checklist

  1. Export your ChatGPT data under Settings, Data controls, Export data. The link arrives by email within 7 days and expires 24 hours after it arrives.
  2. In Gemini, open Settings and help, then under Import chats click Add and upload the .zip. Gemini takes up to 5 GB a file and five files a day.
  3. Wait for processing, which can take up to a day. If an import is cut short, delete it and import again.
  4. Bring your memory: copy Gemini's prompt from Import memory to Gemini, ask ChatGPT, and paste the answer back.
  5. Know that imported chats are saved in Gemini Apps Activity and can be used to train Google's models.
  6. Copy your ChatGPT custom instructions into Settings and help, Personal Intelligence, Instructions for Gemini (personal accounts only).
  7. Rebuild your custom GPTs as Gems in the Gemini web app. From November 2026 Gems move to skills.
  8. Check which model your plan includes: Gemini 4 Argon needs Google AI Pro.
