**Your company's brain for AI agents.** Quelvio continuously understands your organization's knowledge across every connected system — what's authoritative, what's recent, what's persistent, what's temporary, and what should be forgotten. Returns cited answers grounded in your authoritative sources, refusing when the corpus doesn't actually answer the question. ## What makes Quelvio different - **Cross-document supersession** — when sources conflict, surfaces the current truth and explicitly names what it supersedes - **Authority-weighted retrieval** — weights documents by who said them on the relevant topic - **Refuses on weak context** — when the corpus doesn't actually answer, says so. No hallucinated numbers, no fabricated citations - **Cross-source synthesis** — reasons across Slack, Confluence, Notion, Drive simultaneously with explicit source attribution - **Lifecycle awareness** — tracks current vs deprecated content, flags stale procedures ## Tools - `query_knowledge` — search across all connected sources with optional synthesis modes (fast / standard / deep) - `list_domains` — discover what knowledge domains your tenant has indexed - `get_source_detail` — chunk-level provenance for any cited result ## Setup 1.
