For architects, system designers and MBSE practitioners. Windows 10 and 11, no payment details, your models stay on your machine.

An aircraft wing with its turbofan, an electric-vehicle chassis and an excavator in transparent cutaway, their controllers joined by glowing copper and teal network lines.

The harness

One harness around
the whole MBSE flow.

Human judgment and AI assistance accompany every step, from the first concept to the connected digital twin, not one tool bolted on at the end. Built for automotive, aerospace, heavy equipment and medical systems.

  1. Concept

    Frame the problem and the candidate concepts.

  2. System intent & requirements

    What the system must do, traced from the start.

  3. Logical architecture

    Functions, ports and the items they exchange.

  4. Physical architecture & networks

    ECUs, wires, buses and the signals they carry.

  5. Evidence

    Checks, bus load and trade studies against your limits.

  6. Digital twin

    A connected model that stays the reference.

What changes

Derive the decision,
with the evidence attached.

Architecture work is revisited for years. Keep the reasoning in the model, not in slide decks and spreadsheets that drift apart.

  1. 01 Architecture

    Derive the architecture, from intent to wire.

    Start from system intent, derive the interfaces, then realise them on ECUs, connectors, wires and networks. Each step stays traced to the one before it.

  2. 02 Evidence

    Derive the evidence from the model itself.

    Checks, bus load, voltage drop and trace coverage are computed from the model, not typed into a report. A check that tested nothing says "not evaluated", never "passed".

  3. 03 Results

    Derive deterministic results you can repeat.

    Same model, same inputs, same answer. Solver runs are recorded with their seed, the change history is hash-chained, and a restore point is captured before the AI writes.

AI assistance, with you in charge

AI proposes. Deterministic engines prove.
You decide.

D3rive exposes the verbs an engineer uses (query the model, check it, solve an allocation, compare candidates) as tools an AI can call. The AI drafts; the checks, computations and solver runs behind its proposals are deterministic and recorded; you review, compare and decide.

  • Every AI action runs with your permissions, your quotas and the same validation as your own edits
  • Answers cite the model elements they were drawn from
  • Changes arrive as a reviewable plan, and Build records a baseline you can restore first
  • The copilot never deletes, and every change it makes is attributed in the history
  1. Ask

    Answers drawn from the model, with links to the elements behind them.

  2. Plan

    A reviewable change set you inspect before anything is written.

  3. Build

    Applies the plan after capturing a project baseline you can restore.

  4. Your own agent

    Drive the same tools over MCP with a personal access token.

To everyone who already backs us: thank you.

Become a backer.
Help the harness grow.

Everything here is Early Access. We are building the systems engineering harness in the open, together with the engineers who will use it. Bring a real evaluation case, show us where the MBSE flow breaks down and where AI assistance should help: backers directly shape what the harness becomes.

Start with the free 14-day Trial, become a backer with Pro to fund continued development, or involve us in a commercial Team or Enterprise deployment. What being a backer means.
