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
付费分析未识别到付费功能
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.
simple and enough, that's just what you need
Es tan útil para investigar
I love this, but I relied heavily on the ability to add my own notes to the highlight. Update. Months later and I cannot find another app that simply highlights and has the option of adding a note. There are a few but they are complicated or too simple. The note feature on this was vital. I'm still looking for a replacement.
It didn't work for me either. But guys if it doesn't work like mine install page marker. It allows you to write and hylight stuff on the page.
good
THIS THING IS ABSOLUTELY PHENOMENAL. SOOOO HELPFUL!
就 highlight 来说,这个插件应该是最好用的了,又不用绑定各种账号各种在线服务,功能也很完整。这个插件是支持快捷键的,作者都用大写的单词强调了,可惜还是有很多人看都不看。快捷键设置在 菜单 - 更多工具 - 扩展程序 - 左上角点开收缩菜单 - 键盘快捷键,或者直接跳到 chrome://extensions/shortcuts ,再配置即可。
I am using your add on and enjoying! Gread job! Really useful! But I have a doubt: what happens when the highlighted webpage is updated? Thanks for all your good work!
사용하기 편하고 잘 동작하고 좋네요.
I use it everyday. It greatly helps with my everyday work research. I would only wish they had a auto backup/sync with my Google account in case I decide to wipe my browser cache.
