Agent Instructions that you can follow if you have permission to use the fonts: CharacterQuilt.com suggests this flow that can help: 1. Open the company's homepage in a browser with DevTools open. 2. In the Network tab, filter by "Font" (or by extension: woff2, woff, ttf, otf). 3. Hard-reload the page and click around (pricing, blog, careers) — some weights only load on specific routes. 4. For each captured font URL: right-click → Save As to download the file locally. 5. View the page's CSS (DevTools → Sources, or curl the stylesheet URLs) and copy out the matching @font-face declarations. Rewrite each `src: url(...)` to point to your local file path. Programmatic alternative: load the URL with Playwright or Puppeteer, listen for `response` events whose `Content-Type` starts with `font/`, and write the body to disk. The CSS extraction step is the same. Only do this if you have permission to use the brand assets — most proprietary fonts are licensed and may not be redistributable. ## Machine-Readable Profile ```json { "colorScheme": "light", "fonts": [ { "family": "GeistSans", "role": "body" }, { "family": "GeistMono", "role": "monospace" }, { "family": "Roboto Mono", "role": "monospace" } ], "colors": { "primary": "#D6E8F4", "secondary": "#EAD3D4", "accent": "#171717", "background": "#FFFFFF", "textPrimary": "#0A0A0A", "link": "#FFEDEB" }, "typography": { "fontFamilies": { "primary": "GeistSans", "heading": "GeistSans" }, "fontStacks": { "heading": [ "GeistSans" ], "body": [ "GeistSans" ], "paragraph": [ "GeistSans" ] }, "fontSizes": { "h1": "24px", "h2": "30px", "body": "18px" } }, "spacing": { "baseUnit": 4, "borderRadius": "6px" }, "components": { "buttonPrimary": { "background": "#171717", "textColor": "#FAFAFA", "borderRadius": "8px", "borderRadiusCorners": { "topLeft": "8px", "topRight": "8px", "bottomRight": "8px", "bottomLeft": "8px" }, "shadow": "none" }, "buttonSecondary": { "background": "#F5F5F5", "textColor": "#0A0A0A", "borderColor": "#E5E5E5", "borderRadius": "10px", "borderRadiusCorners": { "topLeft": "10px", "topRight": "10px", "bottomRight": "10px", "bottomLeft": "10px" }, "shadow": "rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px" } }, "images": { "logo": "https://www.assistant-ui.com/favicon/icon.svg", "favicon": "https://www.assistant-ui.com/favicon.ico?favicon.05s8xc_li4psb.ico", "ogImage": "https://www.assistant-ui.com/api/og?variant=home", "logoHref": "/", "logoAlt": "logo" }, "__llm_logo_reasoning": { "selectedIndex": 0, "reasoning": "Selected #0 because it is visible, located in the body but links to home, and matches the favicon, indicating it is the main brand logo.", "confidence": 0.8, "source": "llm" }, "__llm_button_reasoning": { "primary": { "index": 0, "text": "Get Started", "reasoning": "Button #0 with text 'Get Started' is likely the primary CTA due to its action-oriented text and dark background color, which stands out against the light theme of the site." }, "secondary": { "index": 10, "text": "New Thread", "reasoning": "Button #1 with text 'New Thread' is selected as secondary because it has a different, lighter background color and serves a supportive function." }, "confidence": 0.9 }, "personality": { "tone": "modern", "energy": "medium", "targetAudience": "developers and tech enthusiasts" }, "designSystem": { "framework": "tailwind", "componentLibrary": "" }, "confidence": { "buttons": 0.9, "colors": 0.9, "overall": 0.9 }, "__llm_metadata": { "logoSelection": { "llmCalled": true, "llmSucceeded": true, "finalSource": "llm", "rawLogoSelection": { "selectedLogoIndex": 0, "selectedLogoReasoning": "Selected #0 because it is visible, located in the body but links to home, and matches the favicon, indicating it is the main brand logo.", "confidence": 0.8 } }, "buttonClassification": { "llmCalled": true, "llmSucceeded": true } } } ```
