AI 产品解读Permanent, private text highlighting tool for any web page
Users need to mark up and annotate web pages with persistent highlights that survive page revisits, without relying on cloud services or accounts
1. User visits a web page and selects text via mouse or keyboard
2. User right-clicks to access context menu or uses keyboard shortcut to apply a highlight style
3. Highlight is visually applied to the page and stored locally in IndexedDB via PouchDB
4. On subsequent visits to the same page, the extension automatically restores highlights
5. User can view/manage all highlights via the popup, options page, or overview summary
6. Highlights can be exported as backup files and imported to restore or transfer between browsers
Create text highlights with multiple styles (colors: Red, Orange, Yellow, Green, Cyan, Purple, Grey; plus Redact, Blur, Bold, Italic, Underline, Strikethrough, Monospace, Magnify, Quotation)Highlights persist across browser sessions using local IndexedDB storage (PouchDB)Keyboard shortcut support for applying highlights (up to 10 preset shortcuts)Right-click context menu for highlight creationPopup dialog showing all highlights on current page with search/filter/sortOverview/summary page for viewing, printing, or saving all highlights

- No suspicious network requests found; all external hosts are for static assets, library CDNs, and documentation links

No premium, subscription, payment, or billing mechanisms found. Grep searches for 'premium', 'subscription', 'payment', 'billing' all returned zero matches. The 'upgrade' keyword hit is the CSP directive 'upgrade-insecure-requests' in manifest.json line 3 - a standard security feature, not a paid upgrade. The 'license' hits are from third-party MIT license text in libraries. The 'pro' hits are false positives from minified code variable names and CSS classes. No feature gating, no Stripe/payment integration, no upgrade prompts found.

- No login, sign-in, account, or authentication mechanisms found in source code. Grep searches for 'login', 'sign in', 'account', and 'password' returned no relevant matches. All data is stored locally using PouchDB with IndexedDB adapter (line: 'new PouchDB("sos", {auto_compaction:true, adapter:"idb", revs_limit:10})'). Store description explicitly states: 'This process is completely private. The location and contents of your highlights never leave your browser.' The 'auth' and 'token' keyword hits are false positives from library code (Angular, jQuery, PouchDB), CSS class names (.token for highlight styling), and third-party license text.
this will be awesome if auto backup to google drive or other services be available i used very much extensions but this is the best one of them.
I have been using this extension for years. Everything I read online I highlight. I have added many other colors, some with shortcuts.
this is honestly life changing. i was sitting here reading a school web assignment, thinking wow i would love to just highlight this rn. looked it up and here it was.
단축키 설정 할 수 있는 방법 공유합니다! 1. 주소창 우측에 위치한 퍼즐 모양처럼 생긴 '확장 프로그램' 버튼을 누른다. 2. 팝업한 창의 가장 아래에 위치한 '확장프로그램 관리' 를 누른다. 3. 들어간 페이지의 좌측 메뉴에 위치한 '단축키'를 클릭한다. 4. 화면 중앙에서 super simple highlighter 를 찾아서 원하는 단축키를 설정 한다. Dear developers, Thank you for providing such a useful service:) It is the most simple, concise, and convenient extension I've ever used. However, I have one request: I set up a shortcut in "chrome://extensions/shortcuts" page, and everything is perfect except the highlight name. Since you named the highlights like "highlight #N," users have to guess or check the color one by one each time to set the shortcut. Could you please rename them in more intuitive ways, like red, green, bold, etc?
a pity it can't sync with google account :(
The best one no doubt!
Works perfectly, just give permissions, select the text, write click and find the tool, select color
단축키 설정해도 안되는데요..
Stopped working
Doesn't work with latest version of Chrome?!
