This page explains how the Software Design Document Generator works, who it is designed for, and how it helps you capture architecture decisions in a single, structured document. The goal is to support conversation between engineers, product teams, and stakeholders without forcing a rigid template.

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.
The generator is useful for teams that want clear design docs without heavy process, and for individual developers who want to document work in a consistent way. It is especially helpful when you have several audiences: engineers, product owners, security partners, and leadership.
Common audiences: Technical leads, Individual contributors, Architecture and security reviewers.
A good design document makes future change easier. It gives new team members a starting point, provides context for security and reliability decisions, and reduces the risk of “architecture in someone’s head” when people move on.
This generator does not enforce a particular method or framework. It gives you a structured outline so you can focus on writing down what matters most for your system.
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.
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:
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.
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.
