Overview
Smart keyword highlighting to improve focus. Uses CSS Custom Highlight API, adaptive contrast, and persistent registry.
Smart Highlighting: Automatically detects and highlights: Uppercase words (e.g., "IMPORTANT") Capitalized words (e.g., "Keyword") Mixed case and hyphenated words CSS Custom Highlight API: Uses the modern CSS Custom Highlight API for high performance and native-feeling highlights without cluttering the DOM. Adaptive Contrast: Intelligently adjusts highlight colors based on the background color (light or dark) to ensure readability. Smart Exclusions: Ignores sentence starters to prevent over-highlighting. Skips specific tags like scripts, styles, inputs, code blocks, and links (anchor tags). Respects contenteditable elements. Custom Highlighting: Define custom keywords with specific colors (e.g., yellow: Python, Java). Supports case-insensitive and whole-word matching. Advanced Keyword Registry: Persistent Memory: Remembers highlighted keywords per-domain or globally (*.*). Retroactive Highlighting: If a keyword is discovered mid-sentence, it gets added to the registry. On subsequent visits (or retroactively on the same page), it will be highlighted even if it appears at the start of a sentence. Configurable Scope: Define maximum registry size and scope (global vs. domain-specific). Customizable: Toggle extension on/off globally or per-site. Manage site exclusions/inclusions via the options page. Advanced Settings: Minimum Words in Block: Configure the minimum word count for a block to be highlighted (default: 10). Custom Colors: Adjust the background highlight colors and opacity for both light and dark modes.
