- Workspace Oversight — List and audit documents within your specific workspaces to maintain organizational control
- Extraction Model Management — List available document types (Resume, Invoice, Receipt, etc.) supported by your account
- Real-time Status Tracking — Retrieve the parsing status and technical metadata for any uploaded document
- Metadata Insights — Quickly identify processing errors or missing data across your document library directly from chat
How it works
