About the Software Design Document Generator

The Software Design Document Generator walks you through the core sections of a design document, from project overview to deployment and operations. It gives you prompts for each part so you can turn scattered notes into a complete, readable design.

Instead of starting from a blank page, you capture the story of your system in small steps. The generator groups your answers into a single document that you can paste into your internal wiki, export as text or Markdown, or adapt to your organization’s standard template.

• Captures project purpose, goals, and audience.
• Describes architecture, components, and data flows.
• Documents quality attributes, risks, and operational needs.

The Software Design Document Generator is divided into a series of steps that mirror common design document sections. You can complete these in one sitting or revisit them as the design evolves.

• Project basics, where you capture the name, authors, purpose, audience, and a short overview of the system.
• Context and requirements, where you describe the problem, goals, stakeholders, and important functional and non functional requirements.
• Architecture, where you explain the architectural style, technology stack, system context, and key design decisions.
• Components, where you list major components or services with responsibilities, interfaces, and the data they handle.
• Data and interfaces, where you summarize the data model, entities, external APIs, and error handling approach.
• Quality and risks, where you document performance, reliability, security, usability, and significant tradeoffs or risks.
• Deployment and operations, where you describe environments, dependencies, monitoring, rollout strategy, and future work.

When you select “Generate design document” the tool assembles these pieces into a single, export ready document with clear headings and section numbers.

The generator is designed to cover the elements people expect to see in a modern software design document. You can keep things high level for small projects or go deeper for complex systems.

A typical output contains sections such as:

• Introduction with purpose, audience, and system overview.
• Context and requirements with goals, stakeholders, and constraints.
• Architecture overview with style, stack, context, and major decisions.
• Component design with responsibilities and interfaces for each component.
• Data model and interfaces with key entities, data lifecycle, and external APIs.
• Quality attributes, risks, and testing strategy.
• Deployment, dependencies, monitoring, and future work.

You can still add diagrams, sequence charts, and API specifications in your own tools, then reference them from the final document.

The Software Design Document Generator runs entirely in your browser. All logic is implemented in client side JavaScript, and the document text is generated locally on your device.

• No form data is sent to a server while you use the tool.
• No project details or design notes are stored by CyberLife Coach.
• Exports create text files directly in your browser for you to save or manage.

Even with a local tool, you should treat design documents as sensitive. They often contain details about architecture, security controls, and dependencies that would help an attacker. Store exports in the same secure locations you use for other internal documentation.

If your organization has strict handling rules, follow those policies first. You can also keep the generator output general and move deeper technical details into your own private repositories or diagramming tools.

A design document is part of a broader engineering process. This generator supports that process by helping you capture information in a structured way. It does not replace architecture reviews, threat modeling, privacy assessments, or formal approval workflows.

Many teams align their design documentation with internal standards or external frameworks, such as architecture review boards, change management practices, or secure development life cycle guidance. You can reference those processes directly inside the generated document where helpful.

If you are unsure whether certain details should appear in a design document, consult with your security, privacy, or legal teams before sharing the document beyond your immediate development group.
