Free PRD Generator — Write Product Requirements in 2 Minutes
Enter your feature details and generate a complete product requirements document with user stories, functional requirements, success metrics, and open questions — ready to share with your team.
Quick Answer
A Product Requirements Document (PRD) defines what you're building, who it's for, and how you'll measure success. It aligns product, engineering, and design before a single line of code is written. Use this free generator to create a production-ready PRD in under 2 minutes.

Frequently Asked Questions
What is a PRD (Product Requirements Document)?
A PRD is a document that defines the purpose, features, and behavior of a product or feature. It typically includes a problem statement, user stories, functional requirements, success metrics, and scope boundaries. PRDs align engineering, design, and product teams before development begins — reducing rework, miscommunication, and scope creep. A well-written PRD answers "what are we building, for whom, and how will we know it's successful?"
Who should write a PRD?
Product managers typically own the PRD, but the best PRDs are collaborative. PMs draft the document with input from engineering (feasibility and effort), design (user experience), data (metrics and measurement), and stakeholders (business context). This tool gives you a strong starting draft so you can spend your time refining with your team instead of staring at a blank page.
How long should a PRD be?
A good PRD is as short as possible while being complete. For a typical feature, 2-4 pages is ideal. Epics or platform-level initiatives might need 5-8 pages. The key is specificity — every section should add clarity, not length. Avoid vague statements like "the system should be fast" in favor of measurable criteria like "page load under 200ms at p95." This generator produces concise, actionable PRDs that hit the right level of detail.
What is the difference between a PRD and a technical spec?
A PRD defines what to build and why — it focuses on user needs, goals, and requirements from a product perspective. A technical specification defines how to build it — covering architecture, APIs, data models, and implementation details. The PRD comes first and informs the spec. Think of the PRD as the "contract" between product and engineering, while the spec is the engineering team's blueprint for delivery.
