What sections does the PRD include?

Executive summary, problem statement, user personas, goals and non-goals, functional and non-functional requirements, success metrics, out of scope, open questions and an appendix — the standard structure most product teams use.

What is the difference between functional and non-functional requirements?

Functional requirements describe what the product does ('user can reset their password'). Non-functional requirements describe how well it does it — performance, security, accessibility and scalability targets.

Why is an out-of-scope section important?

Explicitly listing what you are not building prevents scope creep and aligns stakeholders. It is often the most useful section because it stops debates about features that were never part of the plan.

How should I write success metrics?

Make them measurable and outcome-focused, like activation rate, task completion time or 30-day retention — not output counts like 'features shipped'. The builder lists each metric you enter as a numbered target.

Can I use this for a feature, not a whole product?

Yes. The same structure works for a single feature. Scope the problem statement and goal to the feature and keep the requirements tight.

A PRD that engineers and stakeholders actually read

A good product requirements document answers three questions before any code is written: what problem are we solving, what does success look like, and what are we explicitly not doing. This builder enforces that structure so your spec is complete, scannable and free of the “we’ll figure it out later” gaps that derail delivery.

How it works

You provide the title, author, problem statement and primary goal, then list personas, functional requirements, non-functional requirements, success metrics and out-of-scope items — one item per line. The tool numbers each list and assembles a complete PRD with an executive summary, a goals-and-non-goals section, a requirements section split into functional and non-functional, measurable success metrics, an out-of-scope list to guard against scope creep, and placeholders for open questions and an appendix. The current date is stamped automatically.

Tips and example

Strong requirements are testable. Instead of “fast search”, write a non-functional requirement like “search returns results in under 200ms at p95”. Instead of “good onboarding”, write a success metric like “activation rate reaches 40% within the first week”.

Lead with the problem, not the solution. If the problem statement is vague, every section below it drifts.
Keep the out-of-scope list honest and specific — it is the cheapest way to prevent arguments later.
Pair this PRD with the user-story builder to break requirements into stories for your sprint.
