Bring your documents safely

Upload readable files, use citations and understand what stays in your workspace.

Choose a readable file

Documents supports PDF, DOCX, TXT, Markdown and CSV. Each file can be up to 25 MB, and a PDF can have up to 500 pages. Use a valid, unencrypted file.

For scanned PDFs, start text recognition (OCR) from the document preview. Choose English, Simplified Chinese or Traditional Chinese, and review the result before using it. Recognition can be paused and resumed; completed pages are saved. Files beyond the size or page limit need to be split before upload.

Open Documents

Understand account storage limits

Your account can store up to 100 documents and 100 MB of document files in total, with a 25 MB limit per file. A message can include up to three documents. Download anything you need to keep before removing unused files.

Ask about the source

Upload a document from Documents or add one to a conversation. You can attach up to three documents to a message. Ask a focused question, and use page or section citations to return to the source.

The document text used for an answer is included with that request. Review the original passage when an answer matters, rather than relying on the generated summary alone.

Keep control of your files

Open a document to read it, download it or start a conversation about it. You can also delete it from Documents when you no longer need it for new answers.

Deleting a document does not rewrite existing conversations. Information already quoted in an answer may still be present in that conversation.

Protect your account

Use a unique password and sign out on shared devices. Account gives you separate actions to sign out here or revoke all device sessions.

For questions about personal information or data handling, read the Privacy page or contact us. Do not include passwords or sensitive source documents in an initial support email.
