From idea to presentation in 4 steps

No blank-canvas paralysis. The AI asks the right questions so you never miss a detail.

01

Brainstorm

Describe your project. The AI guides you through 5 structured phases: overview, actors, use cases, rules, and entities.

02

Generate

One click creates 4 production-quality diagrams: architecture, sequence, ER, and component in Mermaid and PlantUML.

03

Refine

Edit diagrams with a syntax-highlighted editor. Ask the AI assistant to fix, extend, or restyle anything.

04

Present

Generate a self-contained HTML slideshow with animations, backgrounds, and share buttons. Download or go fullscreen.

AI Discovery: 5 Phases of Clarity

The AI interviews you like a senior architect, building a complete requirements spec.

PHASE 1

Overview

PHASE 2

Actors

Users, admins, and external systems. Identify everyone who interacts with your app.

PHASE 3

Use Cases

What each actor can do, step by step, with acceptance criteria

PHASE 4

Business Rules

Constraints, validations, and policies that govern your logic

PHASE 5

Entities

Data model with fields, types, constraints, and relationships

Not just software. Any system.
