Switch from Claude to ChatGPT, or bring Gemini work over

Short answer

To switch from Claude or Gemini to ChatGPT, bring over the current files and a reviewed brief of decisions and unfinished work. Claude can write out its memory and Google Takeout downloads Gemini data, but ChatGPT has no import for either. 1folder keeps the working files: ChatGPT opens them through a connector on Business, Enterprise, Edu or Pro (Pro can’t save); on other plans, attach a copy.

Claude or Gemini saves the current deliverables, then ChatGPT reads the files you choose and updates the same proposal. Export archives stay separate from this working folder.

Set up each app, once

Connect Claude to 1folder

  1. Add a custom connection. Open Customize, then Connectors, then Add, then Custom, then Web. Name it 1folder, enter https://1folderapp.com/mcp, and continue with the detected sign-in settings.
  2. Sign in. Sign in to 1folder when Claude asks. Use the account where the client files will stay.
  3. Choose the folders and press Allow. Pick the Client work space or just the folders for this client. Claude needs View and edit to save the proposal and brief; View only would stop it saving. Press Allow.
  4. Check one saved file. Ask Claude to save Client proposal and return its private link. Open the file and check it holds the full current proposal, not a summary.

Removing a connection in 1folder’s Connections cuts that app’s access at once and leaves its saved files in place, so you can disconnect Claude once the move is done.

Connect the Gemini app to 1folder

  1. Add a custom app on the web. In Gemini on the web, open Settings, then Connected Apps. If needed, open Personal Intelligence first. Under Custom apps, choose Add a custom app (or the add field, for your first one), enter https://1folderapp.com/mcp and follow the prompts.
  2. Sign in. Sign in to 1folder when Gemini asks, using the same account as for Claude.
  3. Choose the folders and press Allow. Pick the same Client work space or folders. Gemini needs View and edit to save Supporting figures. Press Allow.
  4. Check one saved file. Ask Gemini to save Client proposal and return its private link. Open the file and check its contents before Gemini saves the figures.

Custom apps are for adults in the US using a personal account, in English with Keep Activity on. Add the app on the web and use it on the web or phone. Google lists no paid plan.

Connect ChatGPT to 1folder

  1. Add a custom connection. On ChatGPT on the web, open Plugins and press + to add a custom server. Name it 1folder, enter https://1folderapp.com/mcp, set up sign-in and choose Create as a plugin. Older layouts use Apps > Create instead.
  2. Sign in. Sign in to 1folder when ChatGPT asks, with the same account the proposal was saved to.
  3. Choose the folders and press Allow. Pick the same Client work space or folders. Choose View and edit if ChatGPT should update the proposal, or View only if it should just read it. Press Allow.
  4. Check one saved file. Ask ChatGPT to save Client proposal and return its private link. Open the file and check it matches what Claude or Gemini saved.

ChatGPT is where the move ends, so its plan matters most. ChatGPT saves to 1folder on Business, Enterprise and Edu, on the web (not the phone app); on Business an admin or owner adds it. On Pro it can open your files but not save; Plus, Go and Free can’t add it. On those, attach a downloaded copy of the file to the chat.

Requests to try with the connected app

  • In Claude

    “Save Client proposal and Project brief in my 1folder Client work folder. Include agreed scope, price, deadlines, source links, rejected options and open questions.”

  • In Gemini

    “Save Supporting figures in 1folder with units, dates, source links and estimates marked. Add the reporting assumptions to Project brief.”

  • In ChatGPT

    “Read Client proposal, Project brief and Supporting figures in 1folder. Tell me the scope, deadlines and uncertainties you found before editing anything.”

  • In ChatGPT

    “Update the same Client proposal using the confirmed delivery date below. Preserve the agreed price and keep the assumptions section. Return its private link.”

Move from Claude to ChatGPT: export memory, check it, then bring the work

Anthropic lets you review memory in Settings > Your Claude through Manage beside Your memory; older layouts can show Settings > Memory. Its help also describes asking Claude to write out its memories and keeping the result in a local file. Review that text for outdated or unwanted details.

ChatGPT keeps its own memory under Settings > Personalization, and OpenAI’s memory help describes no import from Claude. Paste a short reviewed preference brief into a new chat instead, and ask ChatGPT to use it.

Keep exact requirements and the current deliverable in files. You can read the full text there, rather than hoping the app remembers every constraint.

Switch from Gemini to ChatGPT: download and working files are different

Google’s data download uses Takeout. Its help says the Gemini selection covers Gems data; for activity such as chats, select My Activity, then choose Gemini Apps within the activity data. A download does not remove the data from Google. Keep that archive if you want a record of the old work.

For one current result, Gemini also has export options to Google Docs and tables to Google Sheets, subject to availability and workspace settings. Bring a downloaded file into 1folder if you want to keep it there. 1folder does not automatically sync it with Google Drive.

To change from Gemini to ChatGPT for future work, move the current report, its source table and a brief defining the figures. Do not treat an activity archive as an already restored set of ChatGPT conversations.

Continue one proposal before moving everything

  1. Save the current proposal

    Ask Claude or Gemini to save the actual text and a Project brief. If its custom connection is unavailable, copy the text into a 1folder page yourself or upload a downloaded file.

  2. Check the brief yourself

    For example, the brief might say “two review rounds, $3,200 fixed price, final delivery 27 November.” Confirm those values against the agreement and name any unanswered client question.

  3. Have ChatGPT read and restate it

    If your ChatGPT plan can connect 1folder, ask it to read the files and state the scope, price and deadline it found; otherwise attach the downloaded pages. Correct omissions before asking for an edit.

  4. Save one bounded change

    Change just the delivery date, then open the proposal’s versions and compare. If the edit loses an agreed condition, undo it and make the request more specific.

What changes, and what you still control

  • ChatGPT reads the saved files you point it to. Claude’s memory text and a Gemini download stay outside it, and 1folder moves neither.
  • On Plus, Go or Free, download the saved page as Markdown, Word or PDF and attach it to the chat, then decide which copy you will update next.
  • Files stay private during the move; only you can enable a public read-only link, and a permitted connected app does not need one.
  • You can leave the original connection active to return later, or remove it in 1folder’s Connections. This does not cancel the original app subscription.

Questions

Can I migrate from Claude to ChatGPT automatically?
No. OpenAI’s help describes no import from Claude. Bring the files and a reviewed brief, and keep Claude’s own export if you want the old chats.
How do I change Gemini to ChatGPT without starting again?
Bring the latest report or proposal, supporting files and a brief of decisions. Ask ChatGPT to restate the important details before continuing. Keep a Takeout archive separately if you want the old history.
Can I transfer Claude memory directly into ChatGPT memory?
Not directly. Claude can write out its memory as text. Review it and paste what matters into a ChatGPT chat; that is context for the chat, not an import into ChatGPT’s memory.
Do I need to delete the old chats?
No. Keep the old app and its exports until ChatGPT has picked up the actual work.
Can I undo ChatGPT’s first edit?
Yes, for a file it updated in 1folder. Compare versions and undo the saved change. This does not alter ChatGPT’s conversation or its memory settings.
