HylyTool

Chrome Extension for highlighting web documents

HylyTool turns any webpage into a personal reading workspace. Highlight text in your choice of colors, attach notes to individual highlights, blur distracting or sensitive content, and come back to find everything exactly where you left it — across reloads, tab closes, and browser restarts. Built for researchers, developers, students, and anyone who reads deeply on the web. ❥ Highlight: Select any text on any webpage to highlight it instantly. Choose from five soft pastel presets — Butter Yellow, Cotton Candy Pink, Mint, Periwinkle, and Peach — or pick any custom color. Highlights persist across page reloads without any action on your part. ❥ Annotate: Right-click any highlight to add a plain-text note. A compact editor opens right where you clicked — type your note and save with a click or Cmd/Ctrl+Enter. A 📝 badge marks any highlight that has a note; hover to preview it instantly. Click the highlight to read the full note in a clean read-only view. Right-click again to edit or delete the note without touching the highlight. ❥ Manage: Right-click any highlight to remove it. Re-highlight overlapping text to change colors — existing highlights and their notes are preserved automatically. Export all your highlights and notes as a JSON file to back them up or move them to another device. Import them back in one click. Clear all highlights across every page from the popup if you need a clean slate. ❥ Blur: Enter any phrase in the popup and blur every instance of it on the current page — useful for blocking out spoilers, sensitive information, or distractions while keeping the rest of the page readable. Toggle off just as easily. ❥ Privacy: Everything stays on your device. No accounts, no external servers, no tracking. HylyTool uses only storage and activeTab permissions — the minimum needed to do its job. What's new in v2.0 • Per-highlight notes — Attach a plain-text note to any highlight via right-click. View it with a single click, edit or delete via the same menu. Notes survive page reloads, color changes, and re-highlighting the same text. Included in export/import automatically. • Right-click to delete — Right-click any highlight for a clean context menu. Links inside highlights still open the browser's native menu as expected. • Compound highlights — Selections that span links, citations, or other inline elements are highlighted correctly and stored as a single unit. Delete or recolor them all at once. • Overlap & remainder handling — Highlighting over part of an existing highlight preserves the untouched portions in their original color. Notes on the original highlight carry over automatically. • Cross-node reload fix — Highlights on complex pages (like Wikipedia sentences broken up by footnote links) now reapply correctly on reload instead of being silently dropped. • Export / Import — Download all your highlights and notes as a .json file and restore them on another device or after a browser reset. • Clear all highlights — A single action in the popup wipes all stored highlights across all pages, with a confirmation step to prevent accidents. • Polished color picker — New soft pastel palette: Butter Yellow, Cotton Candy Pink, Mint, Periwinkle, and Peach. Swatches lift on hover, the selected color shows a blue ring, and the custom "+" button fills with your chosen color when active.
