Add files as knowledge
Upload supported documents and images, monitor processing, and verify that extracted content helps the agent.
Open Sources → Content and select Files to upload material that is not available from a public URL. An agent can have up to 50 files. Each file may be up to 50 MB. Supported formats are PDF, DOC, DOCX, TXT, PPTX, XLSX, XLS, PNG, JPG, and JPEG.
Upload carefully
Choose files that are authoritative and readable on their own. A slide deck with sparse bullets or a scanned image can contain less useful context than a well-structured document. Uploading a batch processes valid files sequentially; invalid files are skipped, and a batch is truncated when it reaches the per-agent file limit.
The file list reports readiness with Pending, Processing, Extracting text, Creating embeddings, Completed, or Failed. Treat Completed as the point to begin testing. A file that is still extracting or creating embeddings is not ready evidence for an answer-quality decision.
Review and maintain
Completed files can be previewed, downloaded, or deleted. Preview the extracted material when possible and ask a known-answer question in Playground. If a new file supersedes an older policy, remove the old one rather than leaving contradictory facts for the agent to reconcile.
Files are indexed when they are uploaded. The retrain worker refreshes website and enabled Notion sources, not uploaded files. To update a file, upload the revised artifact and remove the obsolete version after verifying the new result. See Manage knowledge sources for the full source-selection workflow.
