Attach files: CSV, spreadsheets, PDFs and images
You can attach up to ten files to a message; tables from CSV and XLSX, text from TXT, JSON and Markdown, and PDFs open in a full-panel viewer, and the same viewer works for files the assistant produces.

What can be attached
- Up to ten files per message, each labelled with its real extension.
- Spreadsheets and CSV render as tables; TXT, JSON and Markdown render as text.
- PDFs open in the browser's native viewer inside the panel.
- Images open in a lightbox.
A CSV of links is a task list
One practical pattern: export a list of URLs to CSV, attach it, and ask for a summary per row. The assistant reads the file, visits what it needs, and reports per entry, with sources, instead of one blurred paragraph.
Frequently asked questions
Are attachments synced everywhere?
Conversation text linked to your account can persist; raw uploaded image and PDF files are not all cloud-synced in the current release.
Can I preview what the assistant created?
Yes, generated files open in the same viewer.
