From Napkin Idea to PRD in 10 Minutes: A Worked Example
The Starting Point: A Messy Idea
Here is the kind of idea that usually lives on a napkin, in a voice memo, or in a text message you sent yourself at 2 AM:
That is not a spec. It is not even a clear feature list. It is a direction — a rough sense of what the product could be. But it is enough to start with. Here is exactly what happens when you put this into Auto Mode.
Step 1: The Input
You open the generator, select Auto Mode, and type two things:
- Product name: WorkWell
- Description: "An app for people who work from home to track their daily habits — like drinking water, taking breaks, exercising — with streaks and reminders. Kind of like a habit tracker but focused on remote worker wellness."
That is the entire input. Two fields. About thirty seconds of typing.
Step 2: What the Tool Infers
The on-device AI reads your description and starts making structured inferences. Here is what it picks up from those two sentences:
Target users
From: "people who work from home"
Inferred: Remote workers, freelancers, distributed teams
Core problem
From: "track their daily habits"
Inferred: Remote workers lack structure and accountability for wellness habits
Key features
From: "streaks and reminders"
Inferred: Habit tracking, streak counters, push notification reminders, daily/weekly views
Differentiation
From: "focused on remote worker wellness"
Inferred: Not a generic habit tracker — tailored to work-from-home context
Platform
From: "An app"
Inferred: Mobile app (default assumption for habit tracking)
Every inference is marked in the output so you can see what the tool guessed and what you explicitly told it. This transparency matters — you need to know which parts of the PRD are your decisions and which are suggestions.
Step 3: The Generated PRD
The tool produces a structured document with clear sections. Here is roughly what comes out, annotated with why each section turned out the way it did:
Mission & Vision
"Help remote workers build and maintain healthy daily habits through gentle accountability and visible progress." The tool inferred this from your focus on remote worker wellness. You did not state a mission explicitly, so the tool constructed one from the problem and audience.
Problem Statement
"Remote workers lose the ambient accountability of an office environment. Without colleagues nearby, daily wellness habits like hydration, movement breaks, and exercise are easy to skip. Existing habit trackers are generic — they do not account for the specific challenges of working from home." This is inferred from your description. It is reasonable, but you should verify it matches your actual research.
Feature List
The tool generates a prioritized list: habit creation and tracking, streak counters, configurable reminders, daily and weekly views, progress statistics, and settings. Each feature is tagged with a priority level (P0 for core, P1 for important, P2 for nice-to-have). The prioritization is based on what the tool thinks is essential for the described product — you will likely reshuffle these based on your actual priorities.
"Considered, Not Included"
This section is one of the tool's most useful features. It lists things the AI thought about but decided were out of scope: social features (sharing habits with friends), integration with wearables, a coaching or AI advisor feature, and gamification beyond streaks. These are not rejections — they are explicit scope boundaries that prevent feature creep.
Success Metrics
"Daily active users who complete at least one habit per day," "7-day streak retention rate," and "reminder engagement rate." These are inferred from the habit-tracking domain. You should refine them based on your actual business model and what success means for your product.
Risks & Open Questions
"How does this differ from existing habit trackers like Streaks, Habitica, or Loop?" "What is the monetization model?" "Should the app sync across devices?" These are genuine questions that the tool surfaces because your description did not address them. They are the questions a reviewer would ask — the tool just asks them first.
Step 4: What You Do Next
The generated PRD is not a finished document. It is a starting point that you refine. Here is the typical workflow:
- Read the inferred sections. Check whether the problem statement matches your actual research. Verify the target users are correct.
- Reshape the feature list. Reorder priorities based on your actual constraints — timeline, team size, technical feasibility.
- Add your knowledge. Fill in the open questions with your answers. Add custom instructions, specific screens, or technical constraints the tool did not know about.
- Remove what does not apply. If the tool suggested a feature you do not want, delete it. If a section is not relevant to your product, remove it.
- Export and share. When the document reflects your actual product vision, export it as Markdown or PDF and share it with your team.
The Time Breakdown
Here is where the "10 minutes" comes from:
- 30 seconds: Type the product name and description
- 30 seconds: Wait for the on-device AI to generate the PRD
- 5 minutes: Read through the generated sections, check inferences
- 4 minutes: Edit the sections that need adjustment, add your own knowledge
The first pass — from raw idea to a readable, structured PRD — takes about ten minutes. A more thorough review with deep edits might take thirty. But the blank-page problem, which usually costs hours of staring at a cursor, is eliminated in the first thirty seconds.
Try It Yourself
The best way to understand this is to try it with your own idea. Take a concept you have been thinking about — even a rough, half-formed one — and put it into Auto Mode. See what comes out. You might be surprised at how much structure emerges from a single sentence.
The tool does not replace your product thinking. It accelerates the part where that thinking becomes a document other people can read. And that, for most product teams, is the hardest part.
