Build a SaaS MVP with AI
The full path from idea to a shipped SaaS MVP — define and scope the requirements, design the architecture, API, and data model, then build it reviewed, tested, secured, cost-controlled, and deployed.
Turn a fuzzy business need into requirements a team can build from — interrogate the need into concrete requirements, shape them as user stories, and write the PRD.
'Build me a dashboard' means five different products to the five people in the room, and the gap doesn't surface until someone's built the wrong one. Requirements are the boring document that prevents that — the concrete statement of what the product must do, for whom, and how you'll know it's done. The trap is treating a one-line ask as if it were a spec. This workflow puts an assistant to work interrogating the need into real requirements, shapes them into testable user stories, and writes the document the team can build from and argue against.
Each step uses an existing NewPrompt tool, pre-filled by a matching resource. Open the resource to read it, or jump straight into the tool with the inputs ready.
Interrogate the need into requirements
Set up an assistant whose job is to pull a fuzzy business need apart into concrete requirements — asking the who, what, why, and edge cases — instead of nodding along to 'build me an X'.
Shape them as user stories
Turn the requirements into structured user stories — as a role, I want a capability, so that an outcome — with the variable parts explicit, so each one is testable and assignable rather than a vague wish.
Write the requirements document
Assemble the stories, constraints, and acceptance criteria into a product requirements document the team can build from — not a paragraph that means something different to everyone who reads it.
A vague business need becomes a written requirements document — concrete user stories, constraints, and acceptance criteria — so the team builds the same product instead of three different ones from the same sentence.
Use this one to define WHAT the product must do — the full set of requirements, user stories, and acceptance criteria. Use MVP Planning after, to cut that set down to the slice that ships first. Requirements come first; the MVP is a prioritized subset of them.
Requirements state what the product must do; architecture decides how you'll build it. Run this workflow first — its PRD and user stories become the input the AI Project Architecture Workflow designs against. WHAT before HOW, and the same requirements also feed the MVP cut.
No — it interrogates the need you bring and structures the answers. The product decisions stay yours; the workflow makes them explicit, testable, and written down.
A written product requirements document (PRD). Step 1 interrogates the need into concrete requirements, step 2 shapes them into testable user stories (as a role, I want a capability, so that an outcome), and step 3 assembles stories, constraints, and acceptance criteria into a PRD the team builds from.
Work the three steps in your own AI tool: use the system-prompt-generator to set up a requirements-interrogating assistant, the prompt-variable-builder to shape user stories, and the markdown-output-builder for the PRD. NewPrompt supplies the prompts and step order; you run each prompt and own the final document.
Bring the business need or product idea and its context — who it's for, the problem, and any known constraints. Step 1 questions that raw need into concrete requirements. You don't need a spec; the workflow builds one from what you supply, so vaguer input just means more interrogation.

Paste a requirement and ask AI for a plan, and you usually get the requirement summarized back or a generic to-do list that can't actually be executed. Here's how to normalize the requirement first, then have AI build a plan with the ordering, dependencies, and checkpoints a summary leaves out.
A PRD earns its keep by separating the feature somebody asked for from the problem they actually have — then fixing scope, numbering the requirements, and handing the open questions to the people who own them.
A feature arrives as one line — "let users change the pickup location" — and AI splits it the two wrong ways: it restates the spec, or it hands back a task list. Here is how to turn a feature into user stories with AI: sliced by the user's path, each one shippable and checkable on its own.
Cut a product idea down to the smallest first release that proves the core value — separate the real must-haves from everything that can wait, then define the MVP and its success signal.
Design a system's architecture on its real trade-offs instead of a confident diagram — put the model in an architect's seat, work the decisions one at a time, and write down the why.
