Switching from ChatGPT to Gemini: what to do first

No conversation history transfers between ChatGPT and Gemini. Export your ChatGPT data before cancelling, convert the archive into readable documents, and paste the context you need into Gemini manually. Then set Gemini Apps Activity retention deliberately, because the default is 18 months.

Short answer

No conversation history transfers between ChatGPT and Gemini. Export your ChatGPT data before cancelling, convert the archive into readable documents, and paste the context you need into Gemini manually. Then set Gemini Apps Activity retention deliberately, because the default is 18 months.

Step by step

  1. Export ChatGPT before you cancel: Settings, Data Controls, Export Data. Confirm via email, then download the ZIP within 24 hours. Cancelling first does not block export, but losing account access does.
  2. Convert the archive: conversations.json is unreadable as shipped. Convert it into Word, PDF, or Markdown so your history is usable outside any account.
  3. Rebuild your custom instructions: ChatGPT custom instructions do not carry over. Copy the text into Gemini's Saved Info or paste it at the top of new conversations.
  4. Set Gemini retention on day one: myactivity.google.com/product/gemini. Choose 3 months and export regularly, or 36 months if you want Gemini's own history to be your archive.
  5. Cancel ChatGPT Plus last: Only after you have verified the export downloaded and converted correctly.

What actually moves

Nothing moves automatically. There is no import path, no migration tool, and no shared format. What you can carry across is context, and that only works if you have your history in a readable form.

| Thing | Transfers? |

|---|---|

| Conversation history | No |

| Custom instructions | No, retype manually |

| Memory / saved info | No |

| Uploaded files | No, re-upload |

| GPTs / Gems | No, rebuild |

| Your exported documents | Yes, they are yours |

The context trick

The practical way to carry continuity across is to convert your ChatGPT export into Markdown, pick the three or four threads that define your ongoing work, and paste the relevant summary into your first Gemini conversation as background.

That gives Gemini most of what ChatGPT's memory would have provided, in about two minutes, and it works in either direction if you switch again later.

Differences worth knowing

Gemini's retention model runs through Google activity rather than an in-app setting, its export path is Google Takeout rather than a data controls button, and the archive it produces is an activity log rather than a conversation file. None of that is worse, but it is different enough that people assume their history was lost when it was simply somewhere else.

Frequently asked questions

Can I import ChatGPT history into Gemini?

No. There is no import feature. You can paste context from your converted export.

Do I lose my ChatGPT history if I cancel Plus?

Cancelling keeps the free account and its history, but export before cancelling regardless.

Is Gemini's export better than ChatGPT's?

It is more complete but less readable, since Takeout ships an activity log rather than a conversation file.

Can I use both at once?

Yes, and many people do. Export from both periodically so your archive is not split across two accounts.
