PRD Generator: Write a Product Requirements Document
Answer six short rounds of questions and get a filled-in product requirements document — problem statement, target users, user stories, scope in and out, success metrics and technical constraints. Copy it as Markdown when you are done. Everything runs in your browser; nothing is sent anywhere.
What are you building?
Every product requirements document opens with a one-paragraph summary. These three answers become it.
Write it the way you would say it out loud to a friend.
Writing a product requirements document that survives contact with a build
A product requirements document is the shortest written agreement about what a release will do. It is not a design, not an architecture, and not a project plan. It is the artefact everyone points at when a new idea arrives in week five and somebody has to decide whether it belongs in this release or the next one.
Most founders do not need a longer PRD template. They need a finished one. A blank product requirements document template is easy to find and hard to fill in — the hard part is not the headings, it is deciding what stays out. That is why this PRD generator asks questions in order and writes the answers into the standard sections, instead of handing you an empty outline.
Two sections earn their place more than the rest. The out-of-scope list is what keeps a first release finite; without it, every conversation reopens the whole plan. And the open-questions section is what stops a document from bluffing — a PRD that admits three unresolved decisions is more useful than one that quietly invents answers for them.
Write the document before you price the work. A scope that has been argued down to its essentials estimates differently from a wish list, and the difference shows up in the build, not in the spreadsheet.
What the PRD template covers
- Overview
- One paragraph a stranger can read and understand what the product is.
- Problem statement
- The pain, the people who have it, and how they cope today.
- Target users
- One primary user named specifically, plus whoever else is involved.
- User stories
- One line per scope item, in the as-a / I-need / so-that form.
- Scope in and out
- The list you are building, and the list you have agreed not to.
- Success metrics
- What you will measure afterwards to decide whether it worked.
- Technical constraints
- Platforms, integrations and the limits that are not negotiable.
- Open questions
- Everything still undecided, written down instead of guessed at.

Product requirements document FAQ
What is a product requirements document?
A product requirements document (PRD) is the written agreement about what a product release will and will not do. It states the problem, names the users, lists the scope in and out, defines the success metrics and records the technical constraints. It is not a specification of how to build the thing — that is a technical design document. The PRD is what everyone involved can point at when a new idea arrives mid-build.
What should a PRD template include?
A usable PRD template has six sections: an overview, a problem statement, target users, user stories, scope (in and out), and success metrics — plus technical constraints and a list of open questions. The generator above produces exactly those sections from your answers, so you get a filled-in document rather than an empty template to stare at.
How do I write a PRD for a startup MVP?
Start from the problem, not the feature list. Name one primary user, describe what they are trying to get done, then write the shortest scope that solves it. The single highest-value section is what you leave out — an explicit out-of-scope list is what stops a first release from growing for months. Finish with one or two measurable success criteria so you can tell afterwards whether the release worked.
How long should a product requirements document be?
One to three pages for a first release. A PRD that nobody finishes reading does not do its job. Length comes from unresolved questions, not from thoroughness — if a section keeps growing, that usually means a decision has not been made yet, and writing it down as an open question is more honest than padding the document.
What is the difference between a PRD and an MVP scope document?
A PRD covers the why and the what: the problem, the users, the success metrics and the constraints. An MVP scope document covers the how much: which features land in release one, which wait for phase two, and what the sequence implies for effort. They are complementary — write the PRD first to decide what matters, then prioritise features against it.
