Documents and deliverables - Mains

Open documents from an agent reply, the Work session panel, or Atlas. The viewer lets you inspect the result beside the conversation.

Supported previews

Format	Extensions
Word	`.docx`
Excel	`.xlsx`
PowerPoint	`.pptx`
PDF	`.pdf`
Markdown	`.md`, `.markdown`
Plain text	`.txt`

Legacy Office formats such as .doc, .xls, and .ppt use the external-app fallback. If a preview cannot render a file, use Open with…. The viewer previews files. Use an agent follow-up or the appropriate external editor to change an Office document. Native Atlas Pages have their own editable block interface.

Sources and deliverables

In Work, Sources shows material used by the run. Deliverables shows output files the agent produced. A temporary rendering image used to preview a document is not a separate deliverable. A file’s appearance in Deliverables does not create a permanent Atlas copy. Ask the agent for a concrete output and format:

Create a project brief as a Word document.
Use the attached notes and include a milestones table.

Export and save

Choose Save a copy… to put the original file where you want it. Image downloads also retrieve original bytes, even when the chat shows a smaller preview. Choose Save to Atlas to keep a library snapshot that survives deletion of the conversation. To preserve a later edit, keep a new copy of that result.

Attachments

Uploaded files and images are saved with their conversation and retained when you fork or archive it. You can find them under Atlas’s Uploads view. Deleting a conversation can remove its run-owned files. Save important material to Atlas or export it first.
