Prompt better before you build

Turn your idea into a detailed prompt for any website, mobile app, AI tool, SaaS product

AI coding agents and website builders work best when you give them a detailed prompt, not a generic request. Use IdeaPrompt to brainstorm the idea, discuss the features, define the design language, map the user flow, and leave with a prompt clear enough to bring your idea to life.

Built for developers, vibe coders, indie hackers, business owners, and anyone shipping with AI.

Generic prompt

I want to build an online store for my cake business.

It gives the agent a category, but almost no product, customer, flow, feature, design, or business context.

Detailed prompt direction

Build a responsive cake store for local customers with a cake catalog, custom order form, delivery and pickup slots, photo gallery, WhatsApp checkout, admin order tracking, warm bakery visuals, mobile-first browsing, and a clear launch scope.

Welcome to IdeaPrompt

Start with the conversation, finish with the prompt.

Don't stop at a one-line idea. Talk through what you want to build, who it is for, what it should feel like, and what a user should be able to do from the first visit to the final action.

Whether your idea is a website, mobile app, tool, or SaaS product, IdeaPrompt helps you uncover the right features, constraints, screens, tone, and build instructions before you hand anything to Claude Code, Cursor, v0, Lovable, or another AI agent.

It starts with a half-formed idea.

You don't need a spec, a stack, or the right words. Say it like you'd say it to a friend — the interview does the rest.

# Build: "SitterMatch" — a marketplace for dog owners & sitters

## Overview
A web app where dog owners find, book, and pay vetted local sitters.
Target agent: Cursor. Stack: Next.js 14 + Firebase + Stripe.

## Core features (with acceptance criteria)
- **Auth** — Google + email/password; email verification required.
- **Sitter profiles** — photo, bio, rates, availability calendar.
- **Booking + payments** — Stripe Checkout; funds held until job completes.

## Design system
- Palette "Warm Trust": #F97316 / #0F766E / #FCD34D / #FFFBEB / #1C1917

## Security requirements (non-negotiable)
- All secrets in env vars; never expose keys client-side.

- Validate & sanitize every input; rate-limit booking endpoints.

## What NOT to build yet
- No native mobile app. No multi-currency. No sitter background-check API.

Adaptive interview

A dynamic question path proportional to your idea's complexity — never a fixed script.
