Overview

Product summary

Review the store description, core capabilities, and common use cases.

IMPORTANT. READ THIS FIRST

If the extension causes slowness issues, especially in combination with large, preexisting highlight collections, I recommend *disabling* (not removing) the extension until an update is ready, unless you have a backup.

Read the support/help documents for more information. Please be patient, I'm working my way through teething issues as fast as possible.

DESCRIPTION

This extension lets you make highlights on any web page, and subsequently attempts to restore those highlights when you revisit the page.

This process is completely private. The location and contents of your highlights never leave your browser.

Nice tool !! :) Thanks a lot ... !! :)

Sherrie/Mark Walker2015年6月14日

Having to right click and than choose a color every single time is not the handiest...highlights remain when printing... But glad to have it! Thanks

Loredan Bucur2015年6月7日

Please come up with a fast way of highlighting selected text / double clicked words. The right-click menu is simply too complicated

Ethan Zeigler2015年5月31日

Amazing, but the "share" popup is driving me insane. I don't want to share what I highlighted, I just want to highlight it.

Candida Leone2015年5月26日

Great extension! It would be even more practical/helpful if the highlighting function could be switched on and off from the browser bar. Having to right click and than choose a colour every single time is not the handiest thing.

Josh2015年5月19日

Super Simple. I agree.

João Pedro Borges2015年5月17日

So far so good! Just hoping for a keyboard shortcut.

The Dragon Queen “Thea Everest”2015年4月30日

It works well but it wont allow me to remove what I highlighted which is CRUCIAL!!!!-_-

刘霞霞2015年4月26日

我需要的，可以做标记，非常棒

Victoria Plummer2015年4月24日

Is there a way to share the page and your highlights?

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

Target users: 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

Monetization

No paid features detected

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.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: 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.
