Impetora builds these as retrieval-augmented generation (RAG) systems with permission-scoped retrieval, source citations on every reply, and an audit log that proves which answer came from which document at which point in time. *Updated 2026-04-27. By Impetora.* ## Key signals - **RAG** - Retrieval-grounded by design - **Source-linked** - Every reply cites its document - **Permission-scoped** - Honours your access controls - **EU** - Data residency by default ## What is this capability? Internal knowledge systems are the category of AI surface where employees ask, in natural language, questions whose answers live across your unstructured corpus - HR policies, compliance manuals, signed contracts, SOPs, historical resolved tickets, regulatory filings. Without grounding, an LLM is a confident generator of plausible nonsense; with grounding, it becomes a search engine that explains itself. McKinsey's 2024 State of AI (https://www.mckinsey.com/capabilities/operations/our-insights/the-state-of-ai) finds knowledge management is one of the highest-frequency generative AI deployments and one of the lowest-risk. That makes it the natural first AI deployment for many organisations: low blast radius, immediate productivity lift, real practice for the governance disciplines harder workloads will need. ## How we build it - architecture and components Four components. First, an ingestion pipeline pulling from document repositories (SharePoint, iManage, NetDocuments, Confluence, file shares), parsing with layout-aware extraction, chunking with semantic-boundary respect, writing embeddings to a vector store with source document, page, paragraph, and permission scope attached. Second, a retrieval layer combining vector search with structured filters and applying your existing permission model. Third, a generation layer where a foundation model receives retrieved fragments and the question, returns a grounded answer with citations, and refuses below confidence threshold. Fourth, an observability layer logging every query, retrieval set, response, and feedback signal. ## What makes it production-grade - TRACE applied Trust. Permission-scoped retrieval is the non-negotiable. Vector store carries the same access controls as source repository, enforced at retrieval not presentation. EU-resident vector store and model gateway by default. Readiness. Two-week corpus audit before any system is built: quality, freshness, duplication, permission gaps. We refuse to build on a broken corpus. Architecture. Versioned chunking and embedding configurations, evaluation suites scoring retrieval recall and answer faithfulness, refusal policy below confidence threshold. Citations. Every answer links to source document and specific paragraph. ## Industries we deliver this for Legal (precedent search, internal know-how, drafting libraries), insurance (policy interpretation, claims handler reference, regulatory lookup), banking (product-policy Q&A, AML procedure lookup, compliance reference), healthcare (clinical-protocol search, coding reference, procedure manuals), logistics (tariff lookup, customs procedure reference, exception playbooks), debt collection (jurisdictional procedure lookup, scripts, regulatory reference).

We typically observe substantial share of routine internal questions answered without handoff, meaningful reduction in time-to-answer for escalations (question now arrives with retrieved context), measurable onboarding speed lift. Stanford HAI's AI Index 2025 (https://hai.stanford.edu/ai-index/2025-ai-index-report) reports retrieval-augmented systems materially outperform raw LLM baselines on factuality benchmarks once retrieval is tuned. We do not promise everything correct - a well-built knowledge system refuses confidently; that refusal rate is itself a quality metric. ## Frequently asked questions ### How is this different from a generic LLM-on-our-docs deployment? Generic LLM-on-docs typically lacks permission scoping, evaluation harness, refusal policy, and audit log. Production-grade RAG enforces permission at retrieval, evaluates faithfulness against a labelled set, refuses below threshold, logs every interaction. ### How do you handle access control? Vector store carries same access scopes as source repository. Queries filtered against user identity and group memberships before any chunk is returned. ### How do you stop the model from making things up? Three layers: grounding in retrieved chunks (system prompt forbids world-knowledge answers), explicit citations on every answer, refusal policy below retrieval confidence threshold. ### How fresh is the index? Continuous incremental ingestion with end-to-end latency of minutes from update to retrievable. Tighter loops where real-time matters, periodic reindexes for stable corpora. ### What about multilingual content? Multilingual embedding models that answer in one language from documents in another. EN, DE, FR, ES, LT routinely supported. ### Where is the data processed and stored? EU regions by default. Vector store, model gateway, observability log on EU infrastructure. Indexed documents never used for training. Regional pinning supported. ### How long does deployment take? First production deployment on curated subset reaches end-users in 4-6 weeks. Full enterprise rollout in 10-14 weeks depending on repository complexity. ## About this capability **Internal knowledge systems** - RAG-powered internal Q&A and search across policies, contracts, SOPs, and historical decisions.
