Attach a document to the assistant
1. Attach a document
If you already have it written down in a file, you can attach the file to the assistant instead of describing it. On the assistant's screen, press Attach a document and choose a PDF, a Word file (.docx or .doc), a text file, a Markdown file or a CSV file, up to 5 MB. You can attach up to three. The file's name and how many characters were read appear above the box, and the assistant is told a document is attached. Then ask in your own words, for example "Make the products from this file".
The assistant reads the document only for this conversation. It is not saved: it is gone when you press New chat, open an earlier chat or reload the page, and it does not come back with your last chat, and removing a file from the list above the box deletes it at once. Anything the assistant would change from the document follows the same rule as anything else it changes: a draft until you approve it, unless you made that kind of change automatic. Reading it is limited to the text of the file: a scanned PDF that is only pictures has no text to read, and the assistant says so. If a file is too large, is password-protected, or is a kind it cannot read, the message names the file and says why. Very long documents are cut at the limit, and the file's label says how many characters were read.
