PRD Generator
A PRD, or product requirements document, defines what a product should do: the problem, the target user, the key features, how success is measured, and what's out of scope. This free tool generates a starter outline from your idea and feature list, no signup required.

Example
Idea: “A shared expense app for roommates that automatically splits recurring bills like rent and utilities, and reminds whoever hasn't paid yet.”
Features: “Link a bank account to auto-detect recurring bills, split each bill evenly or by a custom percentage per roommate, send payment reminders on a schedule, show a shared ledger of who's paid and who hasn't.”
Problem
Roommates who split recurring bills manually (rent, utilities, wifi) redo the same math every month and end up chasing whoever forgot to pay over text, which turns whoever tracks it into an unpaid bill collector for the household.
Target User
Renters who split 3 or more recurring bills with roommates and currently track who owes what in a shared spreadsheet, group chat, or by memory.
Key Features
1. Recurring bill detection: links a bank account and flags recurring charges like rent and utilities automatically. 2. Custom splits: divides each bill evenly or by a saved custom percentage per roommate. 3. Payment reminders: nudges whoever hasn't marked their share paid, on a set schedule. 4. Shared ledger: one view every roommate can check to see who's paid and who hasn't, without asking.
Success Metrics
Percentage of monthly bills marked fully paid within 5 days of being split, number of manual payment reminders users send outside the app (should drop over time), and roommate groups still active after 3 months.
Out of Scope
Actually moving money between roommates (this tracks who owes what, it doesn't process payments), splitting one-off non-recurring expenses, and support for households above 6 roommates are all deliberately out of scope for a first version.
Frequently asked questions
1. What is a PRD?
⌄
A PRD, or product requirements document, is a document that defines what a product should do: the problem it solves, who it's for, its key features, how success is measured, and what's deliberately left out of the first version.
2. What should a starter PRD include?
⌄
A starter PRD should cover the problem being solved, the target user, a numbered list of key features, the success metrics that show it's working, and an explicit out-of-scope section so the first version stays focused.
3. Is this PRD generator free?
⌄
Yes. You can generate up to 5 PRD outlines per day at no cost and with no signup required.
4. Can I download the PRD outline I generate?
⌄
Yes. After generating an outline, a "Download as PDF" link appears below the result so you can save it.
5. Is this a finished PRD?
⌄
No, it's a first draft to react to and refine, not a finished document. It's meant to give you real content to start editing instead of a blank page.
