Step-by-step workflow for claude.ai/design — the new design product on Opus 4.7 that shipped with 55M views in 2 days and crashed Figma valuation by $730M. Covers: access and plan requirements, three quick-test prompts (high-fidelity landing page, pitch deck, 45-second animated video), the video-first hack that produces better slide decks than asking for decks directly, and a full 0-to-1 workflow combining Cowork + Claude Design using a DESIGN.md brand system extracted from your folder and applied automatically to every prompt. Plus the copy-any-brand hack via getdesign.md (Mastercard / Airbnb / Ferrari DESIGN.md files you can swap in). Exports to Canva, PPTX, PDF, standalone HTML, or bundled for Claude Code. 1-hour shippable designs for single pages; 2-3 hours for full multi-tab sites.
