Atheon Mark — Web Highlighter

Highlight and organize text on any webpage with custom colors, reusable styles, shortcuts, and a floating toolbar.

Highlight what matters. Your way. Atheon Mark is a lightweight, customizable web highlighter that helps you mark important passages while reading articles, researching topics, studying, or browsing the web. Choose a color, select how to mark text, and keep the tools you need within reach. FOUR HIGHLIGHT TYPES • Background highlight • Solid underline • Dashed underline • Wavy underline Switch between these styles without changing your selected color. The underline options keep text readable while making important passages easy to spot. CUSTOM COLORS AND TEXT STYLING • Start with six built-in color presets and add your own. • Customize highlight colors, text colors, and opacity. • Edit, rename, delete, and reorder presets. • Keep highlight type separate from color selection. FLOATING TOOLBAR The optional compact toolbar puts colors and marking styles close to the text you are reading. Use its icon-based style selector for quick changes, or open the full panel for additional controls. Pin and erase highlights without leaving the page. CUSTOMIZABLE SHORTCUTS Speed up common actions with keyboard shortcuts for pinning a highlight, erasing a highlight, cycling through colors, and clearing highlights. Customize the shortcut combinations to suit your workflow. SIMPLE SETTINGS • Switch between Light and Dark interface themes. • Save your color preferences and restore defaults when needed. • Keep your highlighting tools compact and out of the way. Atheon Mark is designed for everyday reading, note-taking, and research on the web. Mark what matters.
