The dry facts, gathered in one place so the rest of the docs can link here instead of repeating them.
Import & upload
| What | Formats | Size limit | How many |
|---|---|---|---|
| Import into an article | .docx, .txt, .md (no PDF) | — | one file |
| Upload to materials | .pdf, .docx, .txt, .md | 20 MB each | see the upload control |
| Chat image attachments | JPEG, PNG, GIF, WebP | 5 MB each | up to 5 |
A PDF can't be imported into an article, but it can go into your materials library, where it's summarized for you. See Finding Sources & Images with AI.
Chat attachments allow up to 3 files at a time; this is not a total limit for the project materials library. For images, follow the format, size, and count shown by the specific upload control. ZIP and folder imports are covered in Importing Projects.
