Formats & limits
- Common documents (PDF, Word, etc.), images, and text files are supported.
- Each file has a size limit; unsupported types show a clear error.
- Failed uploads block send until you remove or retry the attachment.
After upload
Attachments go to the Agent with your message. PDFs and similar docs can be parsed into your brief for outlines and slide generation. Images can serve as visual references. See Files & source processing for the full workflow.
For files already in the Brief tab, @ reference is often better than uploading again. See @ references.
