The App Hub is a catalog of the built-in tools RelayHub’s AI can use during conversations. It answers the question “what can the AI actually do with my files and data?” Every tool listed here is always available; there is nothing to install or enable. Open it from App Hub in the sidebar.

How Tools Get Used

You do not call tools directly. Ask for what you want in chat (“compare these two contracts”, “chart revenue by region from this spreadsheet”) and the AI picks the right tools automatically. The tool activity appears in the conversation as the AI works.
Custom capabilities beyond this catalog are built as skills. External service connections (Google Drive, OneDrive, messaging platforms) are managed in their own hubs; see Integrations.
