NanoCrew Cortex  ·  Domain AI

An AI that knows
your business.

Most AI tools are built for everyone — so they never quite fit anyone. Cortex is trained from scratch on your documents, your standards, and your workflows. Not a wrapper. A genuine specialist.

Generic AI hallucinates on your domain.
Cortex doesn't.

Live demonstration

Domain expertise, instantly accessible.

Every Cortex answer is grounded in your indexed documents. Paragraph and section citations included. No hallucination — domain precision on every query.

Answers cite exact paragraph and section numbers
Domain terminology and reference codes interpreted correctly
Runs locally — no query leaves your infrastructure

Domain Intelligence

Purpose-built.
Not retrofitted.

Cortex begins with your domain — your regulations, documents, and proprietary knowledge — and builds a specialist AI system from the ground up. The result reasons correctly about your context, speaks your industry's language, and integrates with the systems your team already runs.

The Process

From domain knowledge to deployed AI.

Every Cortex deployment follows the same rigorous process — but every outcome is unique to your business.

01
Domain Audit

We spend time understanding your domain — regulations, standards, internal terminology, and the questions your team needs answered. We map what your AI needs to know.

Discovery · NDA Protected
02
Knowledge Indexing

Your document corpus is ingested and indexed using hybrid vector search — dense semantic embeddings combined with keyword retrieval — so nothing gets missed.

RAG · Qdrant · Hybrid BM25
03
Model Training

We fine-tune a specialist language model on your domain data. It learns your language, your rules, your edge cases — not a generalist with a system prompt.

Fine-tuned LLM · Domain Expert
04
Deploy & Integrate

Cortex goes live on your chosen infrastructure — cloud, on-premise, or hybrid — and connects to your existing systems via API.

Cloud · On-prem · API First
What Cortex delivers

Everything you need.
Nothing you don't.

Deep Domain Knowledge

Trained on thousands of your documents — regulations, standards, manuals, working papers — turning your institutional knowledge into an always-available AI expert.

Hybrid RAG Retrieval

Dense semantic search combined with sparse BM25 keyword retrieval. Technical terms, reference codes, and domain jargon are retrieved accurately every time.

Fine-tuned Language Models

Purpose-trained models that speak your domain's language — correctly interpreting your terminology and reasoning within your compliance framework.

Flexible Deployment

South African cloud, your own on-premise servers, or hybrid. Your data never leaves your designated environment without your explicit authorisation.

System Integration

API-first architecture connects Cortex to the software your team already uses — ERP, document management, custom applications — delivering intelligence in context.

POPIA Compliant

Designed for South African data sovereignty. Access logging, NDA-protected processes, and deployment options that satisfy POPIA obligations.

Production deployment

A Cortex that knows 41 accounting standards — and applies them in real time.

For a South African public-sector consulting firm managing financial compliance for multiple municipalities, we built a Cortex trained on the full GRAP accounting standards corpus, MFMA regulations, mSCOA chart of accounts, and four years of municipal financial reports — over 51 000 documents.

The Cortex is embedded directly into their consulting platform: providing context-aware compliance guidance, drafting financial statement notes, verifying vote code classifications, and flagging irregular expenditure — all in real time against each municipality's active data.

We don't do one-size-fits-all pricing because we don't do one-size-fits-all AI. Every Cortex is scoped, built, and priced to your domain, corpus size, deployment model, and integration requirements.
