The problem
Until April 2026, you couldn't validate an app idea visually without a designer. Founders had two options: pay £3,000–8,000 for a Figma mockup nobody would build, or sketch it badly in Balsamiq and hope investors could see the vision. Both wasted weeks and forced premature decisions on what the product would actually look like.
Product managers had the same problem internally. They wanted to mock a new feature for stakeholder review but design team capacity was always booked out. So features got shipped on engineer-drawn sketches, or simply weren't built.
Claude Design changes the economics. You describe the app in plain English. Claude produces high-fidelity mockups of every screen you need. Interactive prototype with navigation between screens. Voice, video, 3D, shaders if relevant. The whole thing exports to HTML, a folder of source files, or screenshots for your investor deck.
What Claude Design does for apps
- Generates high-fidelity mockups of any app screen (mobile, tablet, desktop) from a text brief
- Creates clickable interactive prototypes you can demo or share via link
- Mirrors an existing design system if you upload your codebase or design tokens
- Produces wireframes (low-fi) and finished UI (high-fi) depending on what stage you're at
- Generates the supporting components: icons, navigation patterns, empty states, error states
- Exports to HTML, a folder of source files for developers, or screen-by-screen PDFs for stakeholders
How to set it up
1
Define the app concept in one paragraph
Write a clear description: target user, core function, key differentiator. This is the brief Claude works from. Optional: upload competitor screenshots as reference.
2
List the screens you need
For an MVP, usually 5-8 screens: onboarding, main dashboard, primary user flow, settings, profile. Claude builds all of them in a single pass.
3
Choose your visual direction
Editorial, playful, technical, premium. Specify colours if you have brand guidelines, or ask Claude to suggest a palette that fits the target user.
4
Generate & iterate
First draft in 10-15 minutes. Use inline comments to refine specific screens ("make the empty state more encouraging", "move the CTA to the top"). Each round of refinement is 2-3 minutes.
5
Export for stakeholders or devs
For investor pitches: export to PNG/PDF and drop into your deck. For developers: export the HTML/folder so they can use it as a starting point. For user testing: share the live interactive prototype link.
Example brief
Prompt
Build mobile app mockups for a fitness coaching platform.
TARGET USER: Personal trainers (UK, 1-5 person businesses) managing 20-80 clients.
CORE FUNCTION: Trainers send programmes, log client check-ins, track progress photos and measurements, communicate via chat.
SCREENS NEEDED (mobile, iOS):
1. Onboarding (3 screens: welcome, what you'll do, sign up)
2. Main dashboard — list of active clients with status badges
3. Single client view — their programme, latest check-in, recent progress photos
4. Programme builder — drag-and-drop weekly schedule, exercise library on the right
5. Chat with a single client
6. Profile/settings
VISUAL DIRECTION: Modern but warm. Sage green primary (#6B8F71), cream background (#FAF8F5), serif headings. Avoid generic "fitness app" red/black aesthetic.
REFERENCES: Trainerize, TrueCoach (but more editorial, less corporate).

Screen 4 — Programme builder
Left: 7-day calendar (drag-and-drop). Right: exercise library with search.
Bottom sheet for exercise detail (sets, reps, video reference).
Screen 5 — Chat
Standard chat UI but with quick-reply chips for common trainer responses ("Great work!", "Try 12 reps next time").
Screen 6 — Profile/Settings
Cards for billing, integrations (MyFitnessPal, Apple Health), business info, sign out.
Interactive prototype ready. Share link: [live prototype URL]
Export options: PNG, PDF, HTML, folder, PPTX.

Frequently asked questions
Can Claude Design create mobile app mockups?
Yes. Describe the app concept and screens you need (e.g., 'fitness tracking app with onboarding, dashboard, workout log, and profile screens'), and Claude Design produces high-fidelity mockups of each screen. Works for iOS, Android, or platform-agnostic designs. Interactive prototypes include navigation between screens.
Is this good enough to pitch investors with?
For pre-seed and seed-stage pitches, yes. Claude Design produces visually polished mockups that founders use in pitch decks to communicate product vision. For UX-critical Series A+ raises or real product launches, you still want a professional designer. The realistic ceiling: Claude Design closes the gap between 'idea on a napkin' and 'we paid £8k for design work.'
Can it generate interactive prototypes I can click through?
Yes. Claude Design generates interactive prototypes including voice, video, 3D, and shader-powered interactions. You can demo the prototype directly, share a link, or export the HTML/folder for developers to use as a starting point.
Can Claude Design match an existing design system?
Yes. If you upload your codebase or design system files, Claude Design automatically picks up your colours, typography, spacing, and component patterns and applies them across new screens. Particularly valuable for teams who want to mock new features in a way that matches their live product.
Do I need to know Figma or any design tool?
No. The whole point is conversational design — you describe what you want, Claude builds it. You refine with inline comments and direct text editing. No Figma, Sketch, or Adobe XD experience required. If you can describe an app feature in plain English, you can use it.
