Right-click typography inspector that displays CSS font properties of any hovered text element

Designers and developers need to quickly inspect typographic styles (font family, weight, size, color, contrast) of text on any webpage without opening DevTools

1. User hovers over any text element on a webpage. 2. Content script (client.js) captures computed CSS styles via getComputedStyle and sends them to the background script. 3. Background script updates context menu items with the captured font data. 4. User right-clicks to see all typographic properties displayed as menu items. 5. User can click any menu item to copy its value to clipboard, or click contrast to open contrastchecker.online.

Target users: Web designers / Front-end developers / Typography enthusiasts / Accessibility auditors

Contrast link opens contrastchecker.online which is a third-party tool; cannot verify if that external site has its own login/paid features

Monetization

No paid features detected

No payment platforms, subscription APIs, feature gating, or upgrade prompts exist in the code. The 'pro' keyword hits are false positives: 'probably' in a comment and 'provided' in a type error string. All features (font family, weight, size, color, letter-spacing, variants, feature settings, variation settings, contrast ratio) are freely available with no gating.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally with no authentication, account creation, or API calls to any external service. It uses only chrome.contextMenus, chrome.runtime messaging, and optional clipboard permissions. The only external URL is contrastchecker.online which opens as a new tab link, not a gated service.
