We build and deploy systems that make businesses understandable to AI, visible to customers, and operationally autonomous. Our three-layer architecture: EchOS (private operational genome), OIL (single orchestration gateway), and ORBIT (public knowledge infrastructure for AI discoverability). ## Curated Catalogue Entries ### EchOS — The Living Operational Genome - What is EchOS?: https://www.aisend.co.za/catalogue/echos/echos-what-is — EchOS is the company's living genome, a continuously growing knowledge brain containing everything from day one to present, consolidating scattered information into one coherent source of truth. - How does EchOS keep company data secure?: https://www.aisend.co.za/catalogue/echos/echos-security — Runs fully on-premises on an isolated network with zero public egress. All processing local, TLS-secured, token-based RBAC. - How do you know if someone accessed or changed something in EchOS?: https://www.aisend.co.za/catalogue/echos/echos-audit — Every action recorded in a tamper-evident cryptographically chained audit log with independent auditor role. - How are credentials and secrets protected?: https://www.aisend.co.za/catalogue/echos/echos-secrets — All credentials stored in a dedicated secrets-management vault, never committed to source control. - Does EchOS create duplicate entries if the same document is uploaded twice?: https://www.aisend.co.za/catalogue/echos/echos-dedup — Content-hashed ingestion automatically detects and prevents duplicate index entries. - What access levels exist in EchOS?: https://www.aisend.co.za/catalogue/echos/echos-access-levels — Four RBAC levels: admin, ingest/search, read-only search, and audit-only compliance review. - Who can access EchOS directly?: https://www.aisend.co.za/catalogue/echos/echos-direct-access — No one. OIL is the sole authorized gateway. Single-gateway security design. - How does EchOS understand relationships?: https://www.aisend.co.za/catalogue/echos/echos-entities — Extracts structured entities (clients, projects, people) and maps them into a knowledge graph. - What happens if two documents contradict each other?: https://www.aisend.co.za/catalogue/echos/echos-contradictions — Automatically flags conflicting statements across documents. - Does older information get treated the same as recent?: https://www.aisend.co.za/catalogue/echos/echos-confidence-decay — Confidence decay model: older facts carry less weight unless reconfirmed. - How does EchOS decide the best way to answer?: https://www.aisend.co.za/catalogue/echos/echos-intent-routing — Intent-routing layer classifies queries and selects direct lookup, semantic search, or both. - What document types can EchOS process?: https://www.aisend.co.za/catalogue/echos/echos-document-types — PDFs, Word, spreadsheets, images (OCR), and email exports. - Does EchOS replace employee knowledge?: https://www.aisend.co.za/catalogue/echos/echos-knowledge-continuity — Retains institutional knowledge from day one, never loses it when employees leave. ### OIL — Operations Intelligence Layer (Single Gateway to EchOS) - What is OIL?: https://www.aisend.co.za/catalogue/echos/oil/oil-what-is — OIL is the only access point to EchOS. It uses the knowledge base with tools to produce detailed, accurate answers. - How does OIL reduce software costs?: https://www.aisend.co.za/catalogue/echos/oil/oil-cost-reduction — Removes need for multiple third-party subscriptions by keeping everything on the single EchOS foundation. - Can we swap out the AI or tools OIL uses?: https://www.aisend.co.za/catalogue/echos/oil/oil-swap-tools — Any layer on top of OIL can be swapped without cost disruption or downtime. - Why does only OIL have access to EchOS?: https://www.aisend.co.za/catalogue/echos/oil/oil-sole-gateway — Single gateway enforces permissions, context, and formatting. Centralized, auditable, consistent access control. ### ORBIT — Public Knowledge Infrastructure - What is ORBIT?: https://www.aisend.co.za/catalogue/orbit/orbit-what-is — Takes public-facing EchOS knowledge and creates an AI-discoverable company knowledge catalogue. - Why does AI discoverability matter?: https://www.aisend.co.za/catalogue/orbit/orbit-ai-discoverability — As AI becomes primary discovery method, businesses without structured knowledge risk invisibility. ### General / FAQ - How do EchOS, OIL, and ORBIT fit together?: https://www.aisend.co.za/catalogue/general/general-how-it-fits-together — EchOS is the brain, OIL is the sole interface, ORBIT is the public catalogue. One connected system. - What happens as technology changes?: https://www.aisend.co.za/catalogue/general/general-tech-changes — Built on EchOS foundation, keeping up means swapping top-layer tools, not rebuilding. - Is EchOS actually on-premises?: https://www.aisend.co.za/catalogue/general/general-on-prem-claim — Deployed entirely within company infrastructure.
