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 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.
No sirve en PDF y es donde más la necesito
Not only does it mark. It will stay after Chrome has been restarted. Best of all, if you want to remove the marker later, simply click the little x in the beginning of it. Remarkable:)
Very good highlighter with multiple color options and very lightweight with no twitch and problems. Simple and easy to use.
Doesn't work for me
I would like the option to add my own notes to highlights, however the ability to assign colors to hot keys has made this one of the more often used extensions in my toolkit.
The ability to write my own notes would bring this extension to the next level.
Thanks a ton for the great extension. However, it really needs a sync functionality, I want my highlights on both Windows and Linux.
This is simple and awesome. The colors are awesome.
Eu gostei muito dessa extensão. É um pouco complicada no começo, mas depois que você entende o mecanismo é bem fácil e ajuda bastante com leituras da faculdade para mim. Para usá-la você precisa selecionar o trecho desejado e depois clicar com o botão direito, aparecerá uma caixinha com a caneta e você também pode escolher a cor (até mesmo personalizar, o que achei o máximo). Muito boa mesmo!
I really like this extension, it's simple yet powerful. The only thing I would love to note is that when I highlight a hyperlink it does not appear as a link anymore - it is clickable of course but the word is no longer blue. That can be confusing, especially since I thought that this extension only changed the "background" color. I'm a dev ops guy so I'm not sure which CSS property or whatever is being altered and whether that's possible or not.
