Any content that isn’t on your public site lives better as a file upload — policies, supplier specs, internal manuals you want the agent to reference.
Add a file

Sidebar → Knowledge → New source → File upload.

Files parse in the background. Status flips to synced when the agent can use them.
| Type | Extension | Notes |
|---|
| PDF | .pdf | Text extraction — scans need OCR first |
| Word | .docx | Tables and lists preserved |
| Plain text | .txt | The cleanest option |
| Markdown | .md, .mdx | Headings help chunking — use them |
Good file practices
- Split giant PDFs. A 500-page PDF is harder to search than 10× 50-page topical files. Break by topic if you can.
- Prefer Markdown when the source allows it. Clean, short, structured — the ideal format for retrieval.
- Remove cover pages and legalese. They dilute searches. Keep the substantive content.
- Name files meaningfully.
shipping-policy-eu-2026.pdf ranks better in citations than doc (2).pdf.
Updating a file
To replace a file: delete the old source, add a new one. A diff-based replace is on our roadmap.

Security
Files are stored in the EU, encrypted at rest. Only your workspace can retrieve them. If you delete a file, it’s purged from the index within minutes and from storage within 24 hours.
Don’t upload documents with customer personal data you wouldn’t want the AI to reference. If a passage can be retrieved, it can appear (heavily paraphrased) in a reply.
