Practical questions,
short answers.

No. D3rive is complementary to established engineering solutions and standards such as SysML v2.

It supports architects and system designers early in systems engineering, connecting functional intent, physical realisation, requirements, checks and trade studies so that the evidence behind final deliverables remains traceable. It exchanges with established toolchains through the open standards SysML v2 and ReqIF; use it alongside the specialist tools and governed processes that produce and approve those deliverables.

You connect your own AI provider API key, and the provider bills you directly. The copilot acts with your permissions: Ask answers from the model, Plan proposes a reviewable change set, and Build applies it after capturing a baseline you can restore. The MCP agent API lets your own agents use the same tools.

The open standards SysML v2 and ReqIF, plus an Excel workbook, HTML and Word reports, and the complete project bundle (.orcp). Trial and Pro exports carry a watermark notice; nothing is removed and every file still opens in the receiving tool. Model import is included in every edition. See the format table.

On your machine, in the database the installer sets up. This site holds your account and licence only, never your models. Online editions send a small licence heartbeat with usage counters, the product version, the platform and a one-way machine fingerprint. It never contains model content, project names, file paths or hardware identifiers.

The product is before version 1.0 and evolving quickly, with regular releases. It is the real product, not a demo, and feedback sent from inside the application reaches the team building it.

Becoming a backer is your way of saying: we believe in this. Pro is the backer edition, and with it you receive:

• A special Early Access price for the full Pro feature set, shown for your country on the Editions page.
• A look inside a B2B product as it takes shape: a way to learn and experience what engineering organisations really need.
• A voice in what comes next: share and file your ideas from inside the application, and see new ideas early.
• A part in a shared belief: that an AI harness and good systems engineering can work in harmony with the people who use them.

Thank you for believing in us. We will do our best to live up to your trust.

Every feature Pro has, for a non-commercial evaluation: fourteen days with one named user and one AI agent, verification, the constraint solver, trade studies, model import, baselines and the copilot in Ask, Plan and Build modes. It is sized for evaluation: up to three projects large enough to open every shipped example, with smaller monthly allowances than Pro, and exports carry a watermark. No payment details are needed. When the Trial ends the application pauses until you upgrade; your models are never deleted.

Commercial use needs a Team or Enterprise licence: write to enterprise (at) getd3rive.com. Trial is a non-commercial evaluation. Pro is the early-access backer subscription for non-commercial use by independent engineers, researchers, education and early supporters: the full feature set for one named user and one AI agent.

Trial and Pro come with community support, and the feedback you send from inside the application reaches the team that builds it. Team and Enterprise include direct support from the D3rive team.

Your account is also your licence. The same email and password sign you in to the application, and the first sign-in activates your installation, so there is no licence key to copy. Creating the account takes a minute and starts your 14-day Trial.

Trial validates its licence online every few minutes. Pro keeps working for up to 5 hours between checks and Team for up to 24 hours, and each new sign-in needs a connection. Enterprise can use an offline, on-premise licence file with no product telemetry.

Yes. Email enterprise (at) getd3rive.com with your team size, environment and what you want to evaluate, and we will agree a path with you.
