System Context - RelayDesk

Enriched Technical + Architecture stages embed validated Mermaid diagrams (context, ER, auth, deploy).

Without Specifys vs with Specifys

Same idea. Completely different starting point for AI and your team.

Without Specifys

20+ prompts, missing requirements

  • Vague chats that lose context mid-build
  • Missing edge cases, roles, and data model
  • Rework when AI invents the wrong architecture
  • No shared PRD for founders, PMs, and engineers

With Specifys

Complete PRD ready to build

  • Full PRD with problem, scope, and success metrics
  • User stories and end-to-end flows
  • Database schema and API endpoints
  • Design direction + IDE-ready prompts / MCP

What a spec is, and what you get

A spec, also called a PRD, is the written plan for the product: who it is for, what it includes, and how it should be built. Specifys writes that plan from your brief. Overview comes first. The other sections are a second step.

  1. 1. Describe the product

    Say what you want to build in your own words. You do not fill out a form first.

  2. 2. Overview

    The first part of the PRD: the problem, who it is for, the main features, and the user flow.

  3. 3. Full spec

    After the overview looks right, you generate the rest. That second step is a separate click.

Sections in the finished spec

  • Overview Problem, audience, features, and user flow
  • Technical Stack, data, and API
  • Market research Who else serves this customer
  • Design Screens and visual direction
  • Architecture How the pieces fit together
  • GEO & SEO How people and search can find it
  • Prompts Build steps you can hand to an AI coding tool

How it works

Three steps from idea to something your team can build.

  1. Questions

    Answer a short brief about your app - pages, features, audience, and constraints.

  2. Spec

    Get a structured PRD with architecture, flows, design direction, and IDE-ready prompts.

  3. Build

    Hand the spec to your team or connect it to your IDE via MCP - then ship with clarity.
