Search and highlight relevant words by meaning, adding a semantic heatmap to webpages — helping you read, not reading for you. — Traditional Ctrl+F only matches exact keywords. Semantic Highlight adds a semantic heatmap to webpages: describe what you're looking for, and it highlights the relevant parts directly in the original text. Great for long-form reading such as novels, research papers, technical documentation, and more. Semantic Highlight is an AI-powered semantic search and highlighting tool — a smart upgrade to the browser's built-in Ctrl+F / Cmd+F. • Finds all semantically relevant content on the page, with minimap navigation • Highlights relevant words at the word level, with color intensity indicating match strength • Supports PDF • Uses cloud-based AI models for semantic analysis. Compared with traditional embedding-based methods, it provides more precise word-level matching, though it is slower • Configurable shortcut (Ctrl+Shift+F, or Cmd+Shift+F on Mac) for quick access • Matching quality, performance, and user experience are rapidly improving Privacy: No personal information or page content is ever stored. The project is open source, so anyone can inspect how it works and how privacy is protected. ———————— 根据含义搜索并高亮原文中的相关词语，给页面加上一层语义热力图：帮你阅读，而不是替你阅读。 — 传统的Ctrl-F只是字面匹配，Semantic Highlight 给页面加上一层语义热力图：描述你想找的内容，直接亮起原文中相关的地方。 很适合阅读长篇文章，比如小说、论文、技术文档等。 Semantic Highlight 是一款 AI 驱动的语义搜索与高亮工具，可作为浏览器 Ctrl+F / Cmd+F 的智能升级版。 * 按语义查找页面中的所有相关内容，并可以通过小地图跳转 * 精确到词级高亮，根据匹配程度显示不同颜色深浅 * 支持PDF * 基于云端 AI 模型进行语义分析：相比常见的嵌入向量方法，可实现更精细的词级匹配，但速度也更慢一些 * 可配置 Ctrl + Shift + F（Mac 为 Cmd + Shift + F）一键打开 * 匹配效果、速度和使用体验都在快速优化中 隐私说明：不会存储任何个人信息或网页内容。代码已开源，任何人都可以查看隐私保护逻辑。
