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.

This extension seems like a great idea: simple and effective, BUT I cannot get it to work. I've attempted different actions, websites, Options, with no success. I may try back b/c this extension looks to be very useful, but it is not working for me at this time. Disappointing. If someone knows the 'secret', I would love to know,

Cruz Cáceres2021年9月9日

Es bastante simple cuando entiendes como funciona, para usarlo por defecto tienes que presionar el botón derecho y buscar la opción de la extensión y eliges el color, pero es mucho mas fácil si configuras una combinación de botones para que se subraye al color que quieras, la opción está disponible, aparece en las preguntas frecuentes del programa.

Salome Pérez Agudelo2021年8月19日

Tiene todo lo que buscaba, necesitaba y hasta más, después de haber probado muchas extensiones de este estilo, sin duda esta es la mejor :-)

NOT WORKING

Mar Cervantes2021年8月12日

Excelente. Lo uso para el trabajo y estudiar. Se pueden personalizar los colores y guarda lo subrayado. Aparece en las opciones al hacer clic derecho. Simple con lo que es necesario, sin publicidad molesta para mejorar a versión pro como otros resaltadores.

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.
