Highlighter is a free Chrome add-on developed by nokla4137 that aims to improve readability by allowing users to highlight key words. This handy tool is designed for those who want to quickly review previously read articles or blog posts and focus on specific sections.

With Highlighter, users can simply drag their cursor over any word or phrase they want to highlight, instantly adding a visual marker to the text. By using the keyboard shortcuts, such as Shift + V to toggle the highlight on or off, Shift + X to clear all highlights, and Shift + Z to undo actions, users have full control over their highlighting experience.

While Highlighter excels at word-level highlighting, it may not be as effective for highlighting entire sentences or paragraphs. However, for individuals who want to quickly revisit specific information within a text, Highlighter proves to be a useful tool.
