Both actions are buttons at the top of Settings → History, and each opens in its own window. To save a single reply or document as a file, see Exporting as files.

Exporting everythingCopy Anchor Link

Export all conversations, then Download export, downloads a .zip. It is put together while it downloads, so there is nothing to wait for first, though a large history takes a while.

• conversations/: two files per conversation. The .md file is the readable version, the same as downloading one conversation. The .json file is everything as stored: every message including model reasoning, artifacts with all their versions, conversation summaries and the list of attached files.
• attachments/: your files, a folder per conversation; uploaded but never sent ones are in unsent/.
• projects/: each project's files. manifest.json lists each project's name, instructions, files and conversations.
• memory.json: every memory note, whether memory is on or not.
• manifest.json: when the export was made, the OCI version, counts, and an index of every conversation.

Active and archived conversations are included; the trash, temporary chats and deleted files are not. You can run one export at a time, and a few an hour. Past 2 GB of attached files, further files are listed in manifest.json but left out, and the manifest says the export was truncated.

Importing from ChatGPT or ClaudeCopy Anchor Link

Imported conversations appear in your sidebar with their original titles and dates. Only what you saw on screen comes across: your messages and the replies you kept (where the other service kept several versions of a reply, the one you were last looking at). Model reasoning is kept where the export includes it. Tool calls, search steps and custom instructions are left out. Neither service includes your files in its export, so attachments are named in the message instead ("Attached in ChatGPT: diagram.png (file not imported)").

• One import at a time. A queued import can be cancelled; removing a finished one from the list does not remove what it imported.
• Up to 512 MB unless your institution changed it. Until processed, the upload counts against your storage allowance.
• Importing again is safe. Conversations already imported are skipped, so you can import a newer export to pick up new ones. To import one afresh, delete it here permanently first, including from the trash.
• Imported messages do not count towards your usage.
• Retention applies. Imported conversations keep their original dates, so if your institution removes inactive conversations, old imports move to the trash at the next cleanup.
• Damaged or unsafe archives are refused with an explanation, and nothing from them is imported. Content the importer does not recognise is left out and counted in the import's details.

If an import fails, the list says why. Most failures are the wrong file: upload the export .zip itself.

Deleting your accountCopy Anchor Link

If your institution allows it for your role, you can delete your account yourself under Settings → Account. Export what you want to keep first: deleting cannot be undone. Otherwise, ask your administrator, who can delete it for you.
