Upload Files from Computer

Files can be uploaded directly from your computer and added to a Chat, Agent, or Project as a knowledge source.

Available in	Chat, Agents, Projects
Processing	Preview or full read
File limit	50 files per web chat message, 5 per mobile chat message, and 50 files in Agents
Permissions	Direct uploads require the workspace Upload documents permission. Agent and Project uploads also require edit access.
Sync	None

Select Files from Integrations

Files from connected integrations like SharePoint, Confluence, Google Drive, or OneDrive can be selected and added to a Chat, Agent, or Project as knowledge.

Available in	Chat, Agents, Projects
Processing	Preview or full read
File limit	50 files per web chat message, 5 per mobile chat message, and 50 files in Agents
Permissions	Agent and Project editors can attach files. Each reader needs access to the file in the source system and an applicable connection.
Sync	Files are downloaded when selected and refreshed nightly. Agent knowledge files can also be refreshed manually. Source access is checked when a user reads the file.

Sync integration folders

Use Folder Sync in the Folders row of an Agent or the Context section of a Project to connect entire folders from SharePoint, Google Drive, OneDrive, or Confluence Cloud. Their contents are regularly synchronized. Semantic search applies to text documents, supported spreadsheets are read directly, and images are excluded. Confluence Cloud Folder Sync imports pages from named folders, not page attachments.

Available in	Agents, Projects
Processing	Semantic search for text documents; direct read for spreadsheets; images excluded
File limit	200 files per folder in Cloud; 1,000 in Dedicated deployments
Permissions	Editors with the Attach integration folders permission
Sync	Every 24h or manual

An Agent or Project can attach up to five synced folders.

Library Folders

Folders in the Library hold files for active work in chat, Agents, and Projects. Use Folders when you want to reuse the same files across multiple chats or with your team.

Upload options: Computer, Recent Files, or eligible chat attachments

In the Agent editor, select Add folders in the Folders row, then choose the Library Folder. Folders stay read-only until you select Work in this folder. An Agent can attach up to five Library Folders. Only one can be a working folder.

Available in	Chat, Agents, Projects
Processing	Full read
File limit	100 files, 250 MB total
Permissions	Owner and shared users
Sync	None

Knowledge bases

A Knowledge base enables structured uploading and management as a shared semantic search collection. Cloud workspaces support up to 1,000 files. Dedicated deployments use their configured limit.

Upload options: Computer or API

Available in	Agents, @ in chat, Workflows
Processing	Embedding search
File limit	1,000 files in Cloud; configured limit in Dedicated deployments
Permissions	Owner and shared users
Sync	None

Integration Actions

Knowledge can be dynamically retrieved via actions from integrations through API. This is especially useful for vector databases.

Available in	Agent actions, @ in chat, Workflows
Processing	API call (Embedding search for vector databases)
File limit	Depends on integration
Permissions	Admin-controlled per group/user
Sync	Live data on every request
