Digital & Systems Engineering · AI Products

Engineering systems that hold together — and the AI built on them.

Ghost Systems is a systems-engineering and AI product studio. We bring model-based rigor — architecture, ontologies, autonomy — out of aerospace and into frontier AI tools that don't fall apart at scale.

01 / CAPABILITIES

Model-based engineering, applied end to end.

Decades of aircraft software and systems architecture, turned into tooling and delivery for teams building things that have to be correct.

A.

Systems Engineering & MBSE

Architecture, requirements, and model-based system design that stays coherent as the system grows — not slideware that rots after review.

  • SysML v2
  • Architecture
  • Requirements
  • V&V
B.

Digital Engineering & Ontologies

Turning sprawling domain knowledge into queryable, machine-reasonable graphs — the connective tissue under every serious engineering effort.

  • RDF / RDF*
  • SPARQL
  • Knowledge graphs
  • Semantics
C.

Autonomy & Mission Software

Software architecture for autonomous and collaborative systems, grounded in delivering it on collaborative combat aircraft programs.

  • Autonomy
  • GR&A
  • Software architecture
  • Integration
D.

Applied Frontier AI

We don't just consult on AI — we ship it. The products below run on infrastructure and pipelines we designed and operate ourselves.

  • LLM systems
  • Inference fleets
  • Pipelines
  • Agents
02 / PRODUCTS

Software we build, run, and stand behind.

◆ Generative Fiction

Phantom QuillThe long-form fiction engine

Most AI writing tools lose the plot after a few pages. Phantom Quill is built around continuity — a structured, multi-pass engine and graph-backed story memory that hold a coherent narrative across tens of thousands of words and entire series. Thriller to hard sci-fi, mystery to horror and mature genres, without the creative guardrails that flatten everything else. Age-gated, your work, yours to keep.

Phantom Quill — Generative Fiction Engine
◆ Knowledge Engineering

Onyx‑ApertureMake a domain queryable

A knowledge-engineering platform for teams that need their documents, models, and domain expertise to become a single reasoned-over source of truth. Built on RDF/RDF* and SPARQL with a model-based engineering backbone — the tooling we wished existed in aerospace, now usable anywhere.

◆ Autonomous Delivery

Specter‑LoomThe agentic CI/CD pipeline

An agentic CI/CD platform that plans, writes, tests, and ships continuously — the autonomous engineering layer behind how Ghost Systems delivers at the pace of a much larger team. Available to select partners.

03 / ABOUT
Forged from decades of making aerospace software that could not be allowed to fail — now applied to AI products that don't either.

Ghost Systems was founded by an aerospace software engineer and has grown into a team of engineers who build at the intersection of systems engineering and AI. The team's roots run through United States Air Force collaborative combat aircraft, Navy programs, NASA missions, and commercial aerospace — architecture, MBSE, autonomy, and the full software stack. The discipline that ships flight software is the same discipline behind every product we build.
