What is a Product Requirements Document?

A product requirements document (PRD) is the source of truth for a product feature or release. A good PRD captures the problem being solved, the target user, success metrics, the proposed solution, and the scope boundaries. PMs write PRDs to align engineering, design, and stakeholders before any code is written.

The phrase “PRD” (sometimes “product requirements” or “product requirement document”) is the most common name in product management, but the same artifact also goes by spec doc, product brief, or feature brief. Every product organization has some version of this artifact, even if the format varies.

What goes in a PRD?

A typical product requirements document template includes these sections:

1. Problem statement. What user or business problem this solves, with evidence.
2. Goals and non-goals. The outcomes you’re after, and the things explicitly out of scope.
3. Target users and use cases. Who this is for and how they’ll use it.
4. Success metrics. How you’ll know it worked. Tie back to north star metrics or OKRs.
5. Solution and requirements. The functional requirements, user flows, and edge cases.
6. Open questions. Decisions still needed and who needs to make them.
7. Rollout plan. Launch sequence, feature flags, internal communication.

Forge generates each of these sections from a 3-field input. The output follows PRD best practices PMs at top product orgs actually use, not generic template boilerplate.

PRD example

Here’s a one-paragraph PRD example for a notification preferences feature, written by Forge:

Problem: 23% of new users disable all notifications in week 1, citing email fatigue. We lose engagement and re-activation triggers.
Goal: Reduce blanket-disable rate to under 8% by giving users granular control before they hit overwhelm.
Solution: Notification preferences UI with 6 channel-by-frequency toggles, smart defaults based on signup intent, and a one-click “quiet mode” for power users.
Metrics: Preference-set rate, week-1 retention delta, blanket-disable rate.
Out of scope: Push notification rework, mobile-only flows.

Real Forge outputs are 800-1,500 words with full user flows, edge cases, and open questions. Try the PRD generator to see a complete output for your own feature.

PRD template vs PRD generator

A PRD template gives you a blank document with section headers. You still write every word yourself. A PRD generator does the writing. Forge’s AI PRD generator turns three inputs (feature name, problem, target user) into a structured 1,000-word draft you can edit, refine in chat, or hand straight to engineering.

Both have a place. If you have a strong opinion and just want a clean structure, use a PRD template (we have PRD templates here). If you’re facing a blank page, use a generator. Forge supports both, plus 13 other PM doc types.

PRD vs BRD vs Spec Doc

These names get used loosely. A practical breakdown:

• PRD (Product Requirements Document): What product to build, why, and how to know if it worked. Owned by the PM. Read by engineering, design, leadership.
• BRD (Business Requirements Document): What the business needs from a project. Higher-level, often pre-PRD. Owned by business analysts or program managers.
• Spec doc (Technical Specification): How to build the thing. Owned by tech leads. Read by engineers. Comes after the PRD.

In modern product orgs, the BRD has mostly merged into the PRD’s problem statement, and the spec doc is now a tech-design doc owned by engineering. PMs typically only write PRDs.

How to write a PRD with AI

The fastest path:

1. Pick the doc type. Open Forge and select “PRD” from the planning category.
2. Fill three fields. Feature name, problem you’re solving, target user. Or use Interview Mode to get prompted question-by-question.
3. Generate. Forge produces a complete PRD with problem, goals, metrics, requirements, open questions, and rollout plan.
4. Refine. Use chat to push back, ask for more detail in any section, or run quick actions like “Add Metrics” or “Make Concise.”
5. Review. Run CPO Document Review for a scored critique with specific improvement items.
6. Ship. Export to DOCX, share via link, or chain into the next document (user stories, go-to-market, release notes).

ChatGPT and Claude can also write PRDs from a prompt, but you’ll spend 5+ minutes on prompt engineering and the output structure varies every time. Forge bakes in the structure so you can focus on the content.
