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.

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.
