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
- 目标用户
- Researchers and students studying web content / Readers who want to annotate articles and reference material / Users who want private, local-only web annotation without cloud dependencies / Knowledge workers who need to mark up and return to important web content
- Source code is minified/bundled making line-by-line analysis harder, but core functionality is clearly local-only with no external service dependencies
- 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.
➕➕ If possible, you should add a feature to automatically warn the user and automatically download a backup of highlights when the user decides to uninstall this browser extension. I don't want to regularly remember to maintain backups of highlights from this browser extension, and I also don't want to forget to download a backup of my highlights and lose my highlights. 👍👍 Excellent features for custom text styles. I really appreciate that this extension supports strikethrough for text. Lifesaver for reading and remembering individual text of boring web pages and documentations since I have ADHD.
love this, been using this since my college days about 7 years ago
Great and useful extension for annotating texts in webpages! As a suggestion, adding an ability in its settings to be able to re-order annotations will make the extension better. E.g., I have Yellow highlight, Orange highlight, and Yellow underline items, in order, and would like to re-order them as Yellow highlight, Yellow underline, and Orange highlight, instead of changing each item's preferences. Thanks in advance for considering this suggestion.
So helpful wow! Thank you so much.
近期老是遇到选存的信息丢失,不知道啥原因?
very helpful extension, I really enjoy suing this extension in reading for my PhD study.
Good, but could be simpler. I don't want to keep giving permission for the app to run on different websites and I don't want to keep choosing yellow background. If I've eliminated all other color options and forms of highlighting, why can't I just click on the right-click highligher option and have yellow automatically be applied to the text I've highlighted? Why do I have to click another thing, specifying yellow, first?
love it
Why can't I check the option to use on all websites? Having to confirm every time is so troublesome.
Great tool!
