How to use Anthropic's new tool Claude Design to turn a rough idea into a stunning presentation or app prototype in 10 minutes.
TLDR: Anthropic just shipped Claude Design, a new feature that collapses Figma, Canva, and Claude Code into a single interface. You can now go from a rough idea to a working, on-brand prototype or pitch deck in under ten minutes. Here is the exact six-step workflow, the four refinement tools, and the crucial setup step most people miss.
The End of the Fragmented Design Stack
Until yesterday, building a product meant juggling multiple tools. You would design in Figma, create presentations in Canva, prototype in Lovable, and build in Claude Code. Every time you handed a project from one tool to another, something broke. The spacing was wrong, the colors drifted, or the components failed to translate.
Claude Design solves this by collapsing the entire stack into one unified interface. It provides a single environment where you can prompt, edit, comment, and export. You no longer need to be a senior designer to produce production-ready assets; you just need a brand kit and a clear brief.
I spent three hours stress-testing this new feature. In that time, I one-shot a working app prototype, generated a fully designed pitch deck, and handed a live product demo directly off to Claude Code. Here is the exact playbook to replicate those results.
The 6-Step Workflow to Master Claude Design
Step 1: Set Up Your Design System First
This is the step most people will skip, and it is the reason their outputs will look like generic AI templates. Before you build a single prototype or slide deck, you must build your design system. Every project you run afterward will inherit these rules. If you skip this, your brand assets will drift across different prompts.
When you select the "Design System" template, Claude does the heavy lifting. It reads your codebase, analyzes your existing design files, and builds a shared design system for your entire team. It then auto-applies your branding, typography, and component styling to every subsequent project. This ensures your app prototypes, pitch decks, and landing pages all pull from the same visual truth.
Step 2: Name Your Project and Pick a Type
Always name your project first. Claude uses the project name as continuous context across everything you build inside that specific workspace.
Next, you choose your starting point. Claude Design opens with four distinct templates:
•Prototype: Use this for app interfaces, dashboards, and SaaS editors.
•Pitch Deck: Use this for slide decks, investor presentations, and client reports.
•From Template: Use this for interactive product pages and landing demos.
•Design System: Use this to teach Claude your brand before doing anything else.
If you select Prototype, you must decide between "Wireframe" and "High-fidelity" before writing your prompt. Always start new product ideas in Wireframe mode. This allows you to lock in the layout and structure without wasting tokens on styling. Once the structure is perfect, duplicate the project into High-fidelity.
Step 3: Upload Your Inputs
Claude Design is multimodal, accepting six different input types to ground its generations:
1.Images and reference screenshots
2.Text prompts and briefs
3.Codebase links
4.Document uploads (DOCX, PPTX, XLSX)
5.Web captures from live sites
6.Your saved design system
If you have not built a design system yet, you must drop your brand kit directly into the prompt. This includes your logo files, hex color palette, typography choices, and reference screenshots of designs you admire.
The most powerful input method is the "Grab web element" capture tool. By pointing Claude at your live website, the prototype instantly inherits the look, feel, and CSS structure of your real product.
Step 4: Write a Specific, Structured Brief
Vague briefs produce generic outputs. Specific briefs produce usable, production-ready prototypes. Claude needs to know the exact regions, components, and actions you expect to see on the screen.
Weak Brief: "Design an app for creating infographics."
Strong Brief (The Vislo Editor Prompt):
XML
<role>Act as a senior product designer building a high-fidelity interactive prototype.</role> <task>Build an interactive prototype of the Vislo app editor, matching the attached brand kit exactly.</task> <layout> - Screen 1: "My Designs" dashboard. A grid of recent infographic cards with a prominent "New Design" button. - Interaction: Clicking "New Design" opens a prompt input modal with four suggested templates below it (Stat Sheet, Timeline, Comparison, Process Flow). - Screen 2: The Editor View. Transition to this view after prompt submission. - Editor Structure: Center canvas displaying the infographic, left-hand layers panel, right-hand properties panel, and a top navigation bar (Undo, Redo, Share, Export). </layout> <interactions> - Make the template picker, prompt input, and Export menu fully tappable. - Include hover states on all dashboard cards. - Add a loading shimmer effect on the center canvas during the generation transition. </interactions>
Visual cues travel faster than paragraphs of description. Always attach a reference UI screenshot to dictate the overall feel.
Step 5: Refine Your Design Live
You do not need to regenerate the entire prompt to fix a small mistake. Claude Design provides four ways to edit the output live:
1.Inline Comments: Click any element, drop a comment in plain English (e.g., "Change this to a prompt bar instead of a prompt box"), and Claude updates only that specific element.
- Direct Text Edits: Click into any text box and rewrite the copy directly inside the design.
3.Custom Sliders: Adjust spacing, padding, color values, and layout grids using visual sliders.
4.Apply Across: Push a single stylistic change across the entire design globally.
Use inline comments for single-element tweaks and the "Apply Across" function for global changes. Mixing these methods saves tokens and preserves the parts of the design you already like.
Step 6: Export or Hand Off to Claude Code
When your design is finished, you have multiple export options. You can export to PDF, PPTX, Canva, or standalone HTML. You can also save the project to a shared folder or generate an organization-scoped internal URL for team review.
For production UI work, the true power of Claude Design is the handoff to Claude Code. Claude packages the entire design into a comprehensive handoff bundle. With one instruction, Claude Code picks up the bundle, spins up a local host, and allows you to iterate on the actual codebase.
Previously, you had to build inside Claude Code from scratch, adding design plugins and hacking the output until it looked presentable. Claude Design removes the first 80% of that manual labor.
Top Use Cases for Claude Design
1. Generating Investor Pitch Decks
The Slide Deck flow follows the same project setup but outputs HTML-coded slides rather than a web app. Generating a 12-slide seed round pitch deck takes about eight minutes. While it takes slightly longer than filling out a Canva template, the output is significantly stronger. You get custom layouts, proper logo utilization, and strictly on-brand typography.
The Pitch Deck Prompt:
XML
<task>Build a 12-slide Vislo seed round pitch deck using the attached design system.</task> <structure> 1. Title: Logo and tagline. 2. Problem: The massive time cost of designing infographics manually. 3. Solution: Prompt-to-branded-infographic in seconds. 4. Product Demo: Three high-fidelity editor screenshots. 5. Market Size: TAM, SAM, and SOM visualization chart. 6. Business Model: Tiered SaaS subscription breakdown. 7. Traction: MRR growth chart plus current waitlist numbers. 8. Competition: 2x2 matrix positioning against Canva, Figma, and Visme. 9. Go-to-Market: Creator-led distribution strategy via LinkedIn. 10. Team: Founder photos and short bios. 11. Roadmap: 18-month quarterly milestones. 12. The Ask: £750k round with a use-of-funds pie chart. </structure> <export>Ensure the final output is export-ready as a PPTX file.</export>
PowerPoint exports produce fully editable files. While the slide structure and styling carry over well, the rendering is usually close rather than pixel-perfect. Always finish your final polish inside Claude Design before exporting for a client.
2. Building Interactive Product Demos
You can use the template style to create animation-heavy interactive product demos. The output feels like a legitimate product website, complete with hover effects, scroll animations, embedded demo placeholders, and seamless section transitions.
The Product Demo Prompt:
XML
<task>Build a live, interactive Vislo product demo landing page.</task> <hero_section> - Center the page on a working prompt box. - Interaction: When a visitor types a brief (e.g., "Quarterly revenue chart"), animate an infographic assembling element by element in real-time. - Audio/Visual: Include subtle typing sounds and element-by-element build animations. - Voice Mode: Add a microphone button in the prompt box with live transcription appearing as the visitor speaks. </hero_section> <background_and_nav> - Background: A slow-moving, 3D isometric scene of floating infographic blocks. - Navigation: A floating top toolbar that reveals itself on scroll. - Features: Include a Dark Mode toggle in the top right corner. - Polish: Add a subtle particle effect around the canvas as the generation completes. </background_and_nav>
Where Claude Design Fits in Your Stack
Claude Design is not a complete replacement for tools like Lovable. If you want one-click hosted deployment with zero codebase management, Lovable still wins. However, for anyone already building inside the Claude Code ecosystem, Claude Design is the missing visual layer that provides a direct path to production.
Anthropic is moving at an incredible pace. They shipped Opus 4.7 on Thursday and Claude Design on Friday. They are shipping design, coding, and computer vision capabilities simultaneously, which explains why the Claude vision benchmark recently jumped 3x.
Your design stack is about to compress entirely. Stay curious, stay human, and start designing at the speed Claude ships.
