Wait for processing

Each file goes through the processing pipeline:
  1. Uploaded — File is received and stored
  2. Processing — Content is extracted and split into chunks
  3. Indexed — Chunks are embedded and added to the vector index
  4. Ready — Document is searchable by agents
Processing time depends on file size and type. Most documents are ready within seconds to a few minutes.

File size limits

  • Individual file size limits depend on your deployment configuration
  • For SaaS plans, file size limits vary by subscription tier

​
Best practices

  • Use clear filenames — Filenames are used as metadata and may appear in citations
  • Prefer text-based PDFs — Scanned PDFs work but text-based PDFs produce better results
  • Update, don’t duplicate — If a document is updated, delete the old version and upload the new one
  • Organize with multiple KBs — Rather than uploading hundreds of files to one KB, split them by topic
