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.
不更新,可惜了。
Excellent!
Works!
Really helpful. Easy to use and does exactly what it should do.
The concept is great, its easy to use. However the highlighted text would never stay on the website. If I reloaded the page or came back. The highlight was gone and the marker tool correctly warned me that there was a problem and showed me the text it couldn't restore. So i really like this tool, but it is not functional in one of its key aspect. At least not to me.
I love this extension so much, but i found that it can made Chrome (now version is 73) crash often ,just after I using it to highlight oracle official web's document. maybe cause this web is too big. but it will be perfect if this issue be fixed. but I still love it
This does what it's supposed to do, BUT you can't sync your highlights and bookmarks across different devices even if they're all using the same Chrome account! Syncing needs to be integrated. There's an option to import/export, but the new import replaces all current bookmarks and highlights. I suggest a merging option.
it would be very useful if highlights can be printed
Is there an option to set a default color instead of having to choose it every time? Didn't find this feature in the menu. Thanks,
非常好的插件,差点因为没有浮窗面板错过,设置快捷键也很方便。存储本地的,不像 weava 这样要翻墙,速度快,内容稳定。
