HIIE is an AI workflow operating system. A lead copilot named Camelia, working with specialist sub-agents, acts on your prompts to draft the things you ask for — product and business documents, CAD models, images, and multi-step automations (flows). You describe what you want; the agents plan the work, call tools, and produce real outputs you can review and edit.

• Camelia (lead copilot). Interprets your request, decides which tools and sub-agents to use, and coordinates the work end to end.
• Specialist sub-agents.Focused agents handle specific jobs — for example generating CAD, drafting documents, producing images, or wiring up automations — under Camelia's direction.

By default, HIIE routes your prompts to large language models through OpenRouter, which selects and forwards requests to the appropriate model provider. Managed inference this way is metered with service credits.

You may also Bring Your Own Key (BYO). When you supply your own provider key, that model runs on your own account, unmetered by us. BYO keys are encrypted at rest and are never returned to the browser.

AI output can be inaccurate, incomplete, outdated, or unsuitable for your specific purpose, even when it looks confident and well-formed. Treat everything HIIE generates as a draft to be reviewed, not a finished, verified result.

• Human review required. You are responsible for checking and validating anything you rely on — documents, designs, CAD, images, and automations alike.
• Never for safety-critical use without a licensed PE. Do not use HIIE output for manufacturing, structural, electrical, medical, or other safety-critical decisions without independent review and sign-off by a licensed Professional Engineer or other qualified expert. HIIE does not provide PE-stamped or certified work.

You stay in control. The AI proposes and drafts; you approve the actions that matter. HIIE is designed so that you review and decide before relying on an output — the system assists your judgment, it does not replace it.

To do its work, HIIE sends the relevant parts of your prompts and project data to a small set of providers:

• OpenRouter. Prompts for managed inference are transmitted to OpenRouter, which routes them to model providers and returns the response. (BYO requests go to your chosen provider on your own account.)
• Zoo.dev and our build123d CAD service. CAD requests are sent to Zoo.dev (premium CAD) or to our self-hosted build123d CAD service on Railway, which generate the geometry and return the model files.

Your per-user project data is encrypted at rest with server-only keys that are never sent to the browser. See the Privacy Policy for the full list of services and what each receives.

We do not sell your data, and we do notuse your data to train third-party AI models. Your prompts and outputs are used to operate HIIE for you, not to build or improve someone else's model.
