Mercury Reader Alternative Chrome Extension 2026: Top Picks for Distraction-Free Reading

Since Mercury Reader discontinued its Chrome extension, developers and power users have been searching for reliable alternatives that deliver a clean reading experience without the clutter. This guide evaluates the best Mercury Reader alternative Chrome extension options available in 2026, with practical implementation details for those building reading tools.

What Made Mercury Reader Popular

Mercury Reader succeeded because it solved a specific problem: stripping away web page clutter to present content in a readable format. The extension removed ads, navigation elements, and sidebars, leaving only the main article text with customizable typography. For developers consuming technical documentation and long-form articles, this became an essential tool.

The core requirements for any Mercury Reader alternative remain consistent:

• Clean text extraction from HTML pages
• Customizable fonts, sizes, and themes
• Offline reading capability
• Keyboard shortcuts for power users
• Minimal resource consumption

Top Mercury Reader Alternatives in 2026

1. Reader Mode (Built-in)

Most modern browsers now include native reader modes, eliminating the need for extensions in many cases.

Chrome’s Reader Mode:

• Press Alt + M or click the book icon in the address bar
• Available in Chrome 89 and later
• No installation required

Brave Browser’s Reader Mode:

• Cmd + Shift + 8 (macOS) or Ctrl + Shift + 8 (Linux/Windows)
• More aggressive content extraction than Chrome

For developers who prefer not to install additional extensions, the built-in reader mode provides 80% of Mercury Reader’s functionality with zero overhead.

2. Textise Dot Iitty

Textise (textise dot iitty) offers a developer-focused approach to readability. It provides both a browser extension and an API for programmatic text extraction.

Extension Features:

• Custom CSS injection for styling
• API access for batch processing
• Support for 40+ languages
• Export to Markdown format

Installation is straightforward:

# Install from Chrome Web Store (manual)
# Or use the extension with custom CSS

The extension allows power users to define custom extraction rules using CSS selectors:

// Custom extraction configuration
const config = {
  selectors: {
    article: 'article, .post-content, main',
    title: 'h1, .article-title',
    exclude: '.ad, .sidebar, .comments'
  },
  theme: 'sepia',
  fontSize: 18,
  fontFamily: 'system-ui'
};

3. Clearly (Evernote)

Evernote’s Clearly extension remains a solid Mercury Reader alternative, especially for users already in the Evernote ecosystem.

Key Features:

• Multiple reading themes (sepia, dark, black)
• One-click save to Evernote
• Adjustable text width and line spacing
• Paragraph numbering for reference

The integration with Evernote provides a workflow advantage: articles read in Clearly can be saved directly to notebooks for later reference.

4. Mercury Parser (Open Source)

For developers building custom reading tools, Mercury Parser provides the underlying extraction engine that powered the original Mercury Reader.

Installation:

npm install @postlight/mercury-parser

Basic Usage:

import Mercury from '@postlight/mercury-parser';

async function extractArticle(url) {
  const result = await Mercury.parse(url);
  
  return {
    title: result.title,
    content: result.content,
    excerpt: result.excerpt,
    author: result.author,
    datePublished: result.date_published
  };
}

// Extract and process an article
extractArticle('https://example.com/article')
  .then(article => console.log(article.title));

This open-source solution gives developers full control over the reading experience, enabling custom frontends and reader implementations.

5. LeanREAD

A newer entrant in 2025-2026, LeanREAD focuses on developer ergonomics with Vim-style keyboard navigation.

Features:

• Vim keybindings (j/k for scrolling, h/l for navigation)
• Vimium compatibility
• Dark mode with syntax highlighting for code blocks
• Export to HTML, Markdown, or PDF

Configuration is stored in a local JSON file:

{
  "keybindings": {
    "scrollDown": "j",
    "scrollUp": "k",
    "toggleTheme": "t",
    "openOriginal": "o"
  },
  "styles": {
    "fontFamily": "JetBrains Mono, monospace",
    "fontSize": 16,
    "lineHeight": 1.6,
    "maxWidth": "720px"
  }
}

Building Your Own Reader Extension

For developers seeking complete customization, building a basic reader extension involves three main components:

Manifest Configuration

{
  "manifest_version": 3,
  "name": "Custom Reader",
  "version": "1.0.0",
  "permissions": ["activeTab", "scripting"],
  "action": {
    "default_icon": "icon.png",
    "default_title": "Open Reader"
  },
  "background": {
    "service_worker": "background.js"
  }
}

Content Script

// content.js - Extract readable content
function extractReadableContent() {
  // Remove unwanted elements
  const removeSelectors = [
    'script', 'style', 'nav', 'header', 'footer',
    '.sidebar', '.ad', '.comments', '.social-share'
  ];
  
  removeSelectors.forEach(selector => {
    document.querySelectorAll(selector).forEach(el => el.remove());
  });
  
  // Get main content
  const article = document.querySelector('article') || 
                  document.querySelector('main') ||
                  document.querySelector('.content');
  
  return article ? article.innerText : document.body.innerText;
}

// Send content to popup or background
chrome.runtime.sendMessage({
  type: 'READABLE_CONTENT',
  content: extractReadableContent()
});

Performance Comparison

Choosing Your Alternative

The best Mercury Reader alternative depends on your workflow:

• For quick reading: Use Chrome’s built-in reader mode
• For Evernote users: Clearly provides seamless integration
• For developers: Mercury Parser or LeanREAD offer the most flexibility
• For power users: Textise with custom CSS provides complete control

Each option fills the gap left by Mercury Reader differently. Test a few to determine which aligns with your reading habits and technical requirements.
