From a product idea to a website customers can use
What if your next website could start with the business information you already have? DOYJO built Contreol to make that possible. Its AI-powered designer can turn descriptions, product documents and ideas into a website preview, with the editing tools, hosting and account services needed to keep improving and ultimately publish it.
Contreol also demonstrates DOYJO’s ability to build more than a great-looking homepage. Behind the experience is custom software connecting business information, customer accounts, payment processes and managed delivery.
A website that makes its value easy to understand
The experience is designed to be easy to explore, with readable information, clear calls to action and a straightforward way to move from an idea to a working preview.
Your existing business materials become your starting point
Customers can begin with a description, a product PDF, photographs, reference links or existing business material. Contreol carries that information into the project so its content and design reflect the organization’s products, services, audience and goals.
The AI designer works with visual controls for text, images, pages, branding and layout. Customers can make a straightforward edit directly or ask the AI to develop a more involved change. Design choices and business content stay connected as the project evolves, with previews and saved work supporting review.
This approach is useful wherever specialist knowledge needs a better interface: a technical product range, a customer onboarding process, a service questionnaire or a team tool that replaces repetitive manual steps.
Beyond websites: useful tools built for the way you work
Contreol’s development tools support calculators, questionnaires, booking flows, stores and other web applications. A project can define who uses a tool, the information it needs, the rules it follows and the result it should produce. Managed records, file attachments and saved application versions support continuing development.
DOYJO’s work brings interface design together with data, business logic and connections to other services. That combination is directly relevant to enterprise portals, sales tools, operational dashboards and service platforms built around an organization’s processes.

Everything needed to keep moving forward
- Customer continuity: accounts retain projects, uploaded material and the context needed to continue work.
- Review and publication: customers refine a preview, choose launch services and manage later updates from their account.
- Connected billing: QuickBooks invoicing and payment records connect to service activation and account status.
- Managed delivery: hosting, domain connection and optional business email are part of the service workflow.
- Visible resource use: AI credit and activity records give customers a clear view of usage.
- Recovery and control: saved versions and interrupted-request recovery support continued work while safeguards address duplicate attempts and newer edits.
The same engineering decisions matter in a larger organization: preserve context between steps, make responsibilities visible, connect systems at the right points and give people a clear way to review and continue their work.
Radius Labs: a website design in just three minutes
We turned a Radius Labs product fact sheet into an initial website design in just three minutes. After review and refinement, the website went live on its own domain, radlabsgo.com. It’s a practical example of how quickly a good idea can become something customers can explore.
Radius Labs develops random access autosamplers for analytical workflows. Its technical PDF supplied the starting facts and imagery for a website explaining the 1120 Random Access Sampler, sample-access features, fluidics, configuration choices and specifications. Supporting pages, a downloadable data sheet and a contact path help prospective customers move from product research to a discussion with the company.
For manufacturers and other technical businesses, the example shows how existing expertise and product documentation can become a useful customer experience quickly, with a managed path through refinement and launch.
We build the platforms we know how to support
Owned and operated by DOYJO LLC, Contreol brings Brian Bateman’s programming and business experience into a live service. Building and maintaining the full customer journey gives DOYJO practical experience across AI interfaces, custom applications, billing integration, hosting and support.
For your organization, the starting point is the work that needs to happen: which information should move between systems, where a review is required, what a customer or employee should be able to do, and how the process will improve over time. DOYJO can design, build and maintain that connected solution.
