Attach files and URLs so the assistant answers from your client's real content — we extract, chunk, embed, and retrieve only what's relevant per question.

Add sources

1. Open the Knowledge tab inside an assistant.
2. Files — PDF, DOCX, TXT, CSV, Markdown. PDF / DOCX up to 50 MB, TXT up to 10 MB.
3. URLs — crawled on add, re-fetched on a schedule.
4. Plain text — paste an FAQ, policy, or opening hours.

How it's used

• Every reply runs vector search over the knowledge base; only the top chunks enter the LLM context (top-3, dynamic score threshold).
• Short items (hours, policies) can be marked non-vector — inlined into the system prompt so the AI always sees them.
• Embeddings use text-embedding-3-large, stored in Qdrant. The assistant calls the built-in searchKnowledge tool on demand.
• System-managed entries (e.g. allergens, compliance text) are read-only and kept in sync centrally.
