How to switch from ChatGPT to Gemini without paying twice: export 9 days before Plus renews

Start the ChatGPT export 9 days before Plus renews

Nine days is the worst case of three published waits added together. OpenAI's and Google's help pages, read on 3 October 2026, give each one: up to 7 days for OpenAI to email the export, up to a day for Gemini to process the zip, and 24 hours of notice OpenAI asks for before a billing date. Start later and the switch can run past renewal. That's a second $20 month of ChatGPT Plus, paid for an account you were leaving.

1. Day 0, in ChatGPT. Settings, Data controls, Export data, Confirm export. The same day, run Gemini's memory import (below), which takes minutes.
2. When the email lands. Download the zip at once; OpenAI's link expires 24 hours after it arrives.
3. Same day, in Gemini. Settings & help, Import memory to Gemini, Import chats, Add, and choose the zip.
4. Next day. Open a few imported chats from the menu, rebuild your custom GPTs as Gems, then cancel Plus at least 24 hours before the billing date.

Everything in that list runs on a free Gemini account. Google's requirements for the import are a personal Google Account and an age of 18 or over. No paid plan appears in them, so don't buy the Google AI subscription until the imported chats are on screen.

What moves from ChatGPT to Gemini, and what do you rebuild by hand?

Chats and memory move through Google's own import. You rebuild custom instructions, custom GPTs and Projects by hand. The table is one scope: a personal Gemini account outside the EEA, UK and Switzerland, as of October 2026.

The whole switch is two imports and three rebuilds. If you're weighing Claude instead, how to switch from ChatGPT to Claude checks the same export and import routes across seven assistants. Claude takes memory but not chats.

How do you move chats from ChatGPT to Gemini?

You upload the whole ChatGPT export zip to Gemini, unopened. Gemini then lists every conversation in its menu with an imported chat icon. Google's import help page, read on 3 October 2026, gives the route as Settings & help, Import memory to Gemini, Import chats, Add. It says the import is there so you can "continue chats that you started on another platform".

Four limits on that page decide whether it works for you. Each zip can be up to 5 GB, and you can upload five a day. The import is not available in the EEA, Switzerland or the United Kingdom, or inside Gemini on Messages, Chrome or Android XR. It also needs a personal Google Account held by someone 18 or over. A Workspace login from work or school shows no import button at all. Gems, by contrast, are open from age 13, so a 16 year old can build a Gem and still can't import into Gemini.

Two behaviors are worth knowing before you upload. Uploading a zip again overwrites the conversations from the earlier upload, so a second export taken a week later refreshes the set instead of doubling it. And deleting the import as a whole removes every conversation that came from that zip in one action, while More, Delete removes one chat. The page lists no images, files or voice recordings among what comes across. MemoryPlugin's July 2026 guide describes the import as text only. Keep the zip. It's the only copy of your ChatGPT images that leaves with you. Do you lose your chats if you cancel ChatGPT Plus covers what stays on the OpenAI side.

Can I import ChatGPT memory to Gemini?

Yes. Gemini's memory import is a prompt swap that takes about five minutes. In gemini.google.com, open Settings & help, Import memory to Gemini, and copy the prompt Google gives you. Paste it into a new ChatGPT chat, then paste ChatGPT's reply back into Gemini and select Add memory. Google's 26 March 2026 announcement says Gemini will "instantly analyze the information and securely save those details to your Gemini context". The help page adds that Gemini creates a new chat thread to hold it.

Run it with ChatGPT's memory switched on (Settings, Personalization, Memory), or you'll get a thin reply. Then check the result. Open a new Gemini chat and ask it to list what it knows about your work, tools and preferences. Anything missing goes into Instructions for Gemini, which Google's instructions page puts under Settings & help, Personal Intelligence. That's also the home for your ChatGPT custom instructions. Copy those out of ChatGPT's Settings, Personalization before you cancel. OpenAI allows 1,500 characters of them on Free and Go and 5,000 on Plus and Pro, so most people are moving a paragraph or two.

How do you turn custom GPTs into Gems?

You turn a custom GPT into a Gem by copying its instructions into a new Gem and re-uploading its knowledge files. Neither OpenAI nor Google offers an export or import for them. In ChatGPT, open the GPT you built, choose Edit, and copy the Instructions box from the Configure tab. In Gemini, choose Explore Gems, New Gem, name it, paste, and add files under Knowledge from your disk or Google Drive.

Google's Gem tips page says good instructions cover four things, Persona, Task, Context and Format, so let Gemini do the rewrite. Paste this into a normal Gemini chat with your GPT's instructions at the end: "Rewrite the custom GPT instructions below as instructions for a Gemini Gem. Use four headings: Persona, Task, Context, Format. Keep every rule, example and banned behavior word for word where you can. Remove any line that depends on GPT Actions, the GPT Store or ChatGPT-only tools, and list what you removed at the end so I can rebuild it another way. Instructions: [paste here]".

The knowledge side shrinks. OpenAI lets a GPT hold up to 20 files of up to 512 MB each. Gemini's upload limits page, which the Gems page points to, allows 10 files at up to 100 MB each. A GPT with 15 reference PDFs needs them merged into ten before it fits. A GPT you only used from the GPT Store has no instructions you can see. Google's premade Gems, such as Writing editor, Brainstormer and Career guide, cover common jobs. Anything else you write fresh from the prompt above.

Imported chats become Gemini activity, and Google's policy covers training on them

Every chat you import is saved in your Gemini Apps Activity and handled like a chat you typed into Gemini. Google's import page says this plainly: "This data is used to improve our services (including training generative AI models)". If you had ChatGPT's model training switched off, that choice doesn't travel with the zip.

Gemini's privacy hub, read 3 October 2026, adds the numbers that matter. Human reviewers read some chats. A chat a reviewer read is "retained for up to three years" even after you delete your activity. And activity auto-deletes after 18 months by default (3 months, 36 months or never are the other settings). Google's own advice on the same page is not to enter confidential information you wouldn't want a reviewer to see. A three year archive of ChatGPT conversations usually holds some of that. Skim the chat titles in the export's chat.html before you upload, and keep anything about health, money or clients out of the import.

There's another route if you'd rather not hand the archive to Google's consumer app. Whizi reads the same export (conversations.json or the zip) in your browser and lists the chats in its sidebar. From there you can carry a thread on with Gemini Flash or Gemini Pro on Pro and above. Its privacy policy says Whizi "does not use your prompts, files, conversations, voice transcripts, or generated content to train Whizi-owned AI models", though each message you send still reaches the model provider you pick. Where Whizi loses: no Gems, no Gemini inside Gmail or Docs, text only, and a one-time copy with no live sync. The steps are in import chats from ChatGPT.

When should you cancel ChatGPT Plus and pay for Google AI Pro?

Cancel ChatGPT Plus after the imported chats show up in Gemini and at least 24 hours before the renewal date, and pay Google last. OpenAI's cancellation page keeps paid features until the end of the billing period, so cancelling early costs nothing and cancelling late costs $20. If Apple or Google Play bills you, cancel in the store. How to cancel ChatGPT Plus has each route.

The order matters on Google's side for a different reason. Google One, which bills every Google AI plan, says payments are non-refundable in most countries or regions. A plan bought before you know the import works in your account is money you can't easily get back. Since the import runs on a free account, test it first and upgrade after. Google AI Pro vs ChatGPT Plus compares the two $20 plans job by job if you're deciding which one to keep.

Keep the free ChatGPT account for a month after the move. It costs nothing, and your chats stay on it after Plus ends. It's also the cheapest way to re-run the memory prompt or take a fresh export if Gemini dropped something.
