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.
muito objetivo, excelente ferramenta.
Sorry, my bad ! I do have to revise my previous negative rating to a "very positive" after 4 months highly intensive using this extension. It do much better than old version in term of UI, history of highlight, bookmark, import & export Styles Bookmarks & Highlights etc. After enable chrome " mht " file format function. I can save webpage as a single file in mht with all my highlight remained for later off-line viewing. May I suggest that single key assigned as shortcut is also allowed beside combining with "alt" and "ctrl" key. thk, a really useful extension ! Find highlight "export" is not work from time to time ! Is there any solution to fix this problem ? thks.
Hey guess what, it's super simple. The highlight looks really nice and bubbly and is soft on the eyes. My online studying is augmented greatly by this tiny addition. Thank you!
Does what it says. Thanks to the developers.
Awesome!!!!!
It might be better if it provide a one click solution for highlight especially when highlight is used very frequency in a page.
works perfectly fine. it does its job quite well. so no complaints from my side.
Simple, but it works
Is the one I have used for several years now. Even there are no option to export highlighted text to a friendly format keeping the colors I found that I can copy everything and export to Evernote keeping the color format. This works like a charm when summarizing information. Just one problem, there are websites I can not highlight I tried with only text extensions but now When there are websites I can not highlight I just copy it to justpaste.it. Great Job. Thank you
Easy to use! Perfect for those who just want to use it for highlighting
