Annotate web pages with highlights, areas, and element notes. IAMUUID Annotator is the ultimate tool for developers, designers, and researchers who need to leave precise notes on the web. Not only can you annotate anywhere, but you can also lock your window width to ensure you never lose the context of your layout. 🚀 KEY FEATURES: 1. Three Ways to Annotate: - 📝 Text Highlight: Mark important keywords and short phrases instantly. - 📌 Element Note: Pin sticky notes to specific HTML elements (divs, images, buttons). - 📐 Area Note: Draw a rectangle anywhere on the screen to comment on a specific visual area. 2. Strict Width Edition (Unique Feature): - Automatically records the window width when you save a note. - Warns you if the window size has changed when you revisit, ensuring you see the page exactly as it was when annotated. - Perfect for checking responsive designs! 3. Robust Management: - Search, sort, and manage all your notes in a dedicated dashboard. - Full Import/Export capability for data backup. - Privacy-focused: All data is stored locally in your browser. ⚠️ USAGE NOTE: The "Text Highlight" feature is currently optimized for keywords and short phrases. For longer paragraphs or dynamic content, we recommend using "Element Note" or "Area Note" for the best stability. Boost your productivity and keep your web research organized with IAMUUID Annotator!
