Product brief
Laundry delivery MVP
Problem
Customers and riders coordinate pickups in chat. The first version needs scheduling, tracking, and payment.
In scope
Build plan
Phase 1 · 3 weeks
Auth, orders, and payments. Admin tools wait.
You start building while the user, the outcome, and the non-goals are still a guess.
The first version tries to do everything, so it never does the one job that matters.
Tools get picked before anyone has written what the product has to do.
01
Write the product in plain language. A few sentences is enough to start.
02
Platform, users, integrations, and timeline — the choices that change the plan.
03
Scope, stories, requirements, technical notes, and milestones you can hand to a builder.
Problem, users, scope, and non-goals in a document you can share.
The jobs the first version must do, written so a builder can start.
What would prove the product works, before you instrument anything.
Constraints, integrations, and risks tied to the scope you just wrote.
A phased build plan: what ships first, and what waits.
Markdown on the free plan. Links and PDF when you need to send it.
"We had a deck and a group chat. FounderBrief gave us a PRD we could actually build from."

Straight answers about the PRD, who it is for, and how pricing works.
FounderBrief is an AI PRD and build-plan generator. You describe a startup idea and get a product requirements document — problem, users, scope, user stories, requirements, technical constraints, and milestones — before anyone writes code.
FounderBrief is for founders who need to know what they are building and how they will make it. Non-technical founders use it to brief a developer. Technical founders use it to lock scope before the first commit.
A generated PRD includes a short summary, goals and non-goals, user stories, functional requirements, the core experience, success metrics, technical considerations, and a phased build plan with a complexity and budget range.
Yes. Generate your first PRD free — one full generation, no credit card. Paid plans are $18/month, or $15/month when billed annually, for unlimited generations plus shareable links and PDF export.
Brief content is designed to stay on your device. Account details like email and name are stored to operate the service. When you generate a PRD, prompts are processed via Google Gemini through our API and are not permanently stored afterward.
Generate a PRD and a build plan from the idea you already have.
