Draw the logic. Let AI build it right.
Stop writing paragraphs to describe your app. Draw the flow instead.
When you describe a login flow in prose, AI builds 3 screens instead of 7. The error state is missing. The loading screen is forgotten. The conditional branch is ignored. You spend more time fixing the output than you saved generating it.
Drawd is a visual app flow designer that turns your screen designs into structured, AI-ready build instructions -- complete, unambiguous, and impossible to misinterpret.
AI is great at writing code. It is terrible at reading your mind.
You paste a paragraph into ChatGPT describing your app's navigation. It hallucinates screens you didn't mention, skips the ones you did, and connects them in ways that make no sense. You correct it. It misses something else. You try again.
The problem isn't AI. The problem is prose is a lossy format for describing interactive flows. Navigation has structure -- screens, transitions, conditions, error states. Text flattens all of that into ambiguity.
- Upload your screens -- drag images onto the canvas, or start with blank screens
- Draw hotspots -- click and drag on screen images to define tap areas, buttons, inputs, and interactive elements
- Connect the flow -- link screens with navigation arrows, define API calls, conditional branches, and error handling
- Generate instructions -- one click produces structured, multi-file build instructions that AI can follow precisely
What comes out is not a paragraph. It is a complete specification: every screen cataloged, every interaction mapped, every edge case documented.
Infinite canvas. Drag-and-drop screens. Bezier connection lines. Zoom in, zoom out. Rearrange until the flow makes sense visually before a single line of code is written.
Hotspots aren't just "tap here, go there." Define element types, API calls with success/error paths, conditional branches, modals, back navigation, and custom behaviors. The hotspot system captures what actually happens when a user taps, not just where they end up.
Generated instructions are split into structured files -- screen inventory, navigation map, and a platform-specific build guide for SwiftUI, React Native, Flutter, or Jetpack Compose. No ambiguity. No missing screens. No guesswork.
Attach API specs, design guidelines, or reference documents directly to your project. Link them to specific hotspots so AI knows exactly what endpoint to call and what response to expect.
No account. No cloud. Auto-saves to a local .drawd file. Export, import, merge flows from multiple files. Your designs stay on your machine.
- Developers using AI to build mobile apps -- give your AI assistant a spec it can actually follow
- Product managers -- communicate app logic visually instead of writing 20-page PRDs that nobody reads
- Designers -- hand off interactive flows, not static mockups
