    description
    Gmail's font size is too small on laptops, and there is no way to change it. Browser zoom breaks the layout - the sidebar expands, buttons grow, and you scroll horizontally just to read one email. There is no reader mode. The inbox never stops competing for your attention. And prying eyes can read your screen from any angle.
    Chameleon adds four visual lenses to Gmail. Each one changes how email looks on your screen without changing anything in the email itself. Everything runs locally in your browser - no account, no server, no data collected.
    
    🔍 Increase Font Size - Make Gmail text bigger without breaking the layout
    
    Unlike browser zoom, which scales everything (sidebar, buttons, headers, menus), Chameleon increases only the font size of the content you read. Subject lines, sender names, preview text, and message bodies scale to a comfortable size up to 180%. Gmail's interface stays at its default size. No horizontal scrolling, no oversized sidebar.
    Your preferred font size is saved automatically across sessions.
    Best for: Laptop users (especially 13-inch screens), anyone over 40, people with low vision, anyone who finds Gmail's default text size too small.
    
    📖 Reader Mode - Read email like a book
    
    Opens any email or thread in a clean, full-screen reading view. Gmail's sidebar, toolbar, and visual clutter disappear. Your message renders in comfortable serif typography, centered in a 68-character column - the same line width used by books and e-readers.
    Three themes (light, sepia, dark), a 3-step font size control, and thread-by-thread navigation. Single-keystroke activation. Works on individual emails and full threads.
    Best for: Long emails, newsletters, detailed threads, and anyone who struggles to focus in Gmail's default interface. Knowledge workers managing high email volume. People with ADHD or attention difficulties who need fewer visual distractions.
    
    🔒 Visual Privacy - Hide your email from prying eyes
    
    Scrambles visible text in your inbox and email threads using font-based character substitution. Your Gmail looks like gibberish to anyone nearby. In your inbox, hover over any row to reveal that message; in an open email, hold to reveal text behind a moving window. The eye button instantly reveals or re-scrambles everything in one tap. Turn the lens off entirely whenever you want.
    Important: This is visual obfuscation, not cryptographic security. It protects against shoulder surfing - the person sitting next to you in a cafe, train, or open office reading your screen - not a determined attacker with physical access to your device.
    Best for: Shoulder surfing prevention in public. Commuters, cafe and coworking-space workers, open-office employees, anyone handling sensitive conversations in shared environments.
    
    🎯 Focus - Quiet the inbox. 
    
    Dims low-signal inbox rows - promotional, no-reply, and CC'd messages - so the conversations that actually matter stand out. Less noise when you're triaging, without leaving Gmail or changing how it works.
    
    🔐 Privacy and trust
    
    Chameleon runs entirely in your browser. There is no server, no data collected, and no email content ever leaves your machine. The extension uses only two permissions: storage (to save your lens preferences locally) and the mail.google.com host permission (required to apply visual lenses inside Gmail). No analytics. No account. No tracking. Manifest V3.
    
    How it works
    
    Chameleon applies visual transformations inside Gmail using CSS and font substitution, entirely within your browser. No email content is modified, stored, or transmitted. All lenses run locally and only change how the page appears on your screen. Activate one lens or combine several from the Chameleon icon in Gmail's toolbar.
    
    What Chameleon is not
    
    Not encryption - Visual Privacy provides visual obfuscation, not cryptographic security.
    Not a data collection tool - the extension does not collect or transmit any email data.
    Not a Gmail replacement - it changes how you see email, not how Gmail works.
    
    Permissions explained
    
    Storage - saves your lens preferences (active lenses, zoom level, reader theme) locally in your browser.
    mail.google.com - required so Chameleon can apply visual lenses inside Gmail. No other sites are accessed.
    
    Built by an independent team
    
    Chameleon is built by Chameleon Labs, an independent team based in Europe. We do not take funding that requires us to monetize user data. We will never sell data, show ads, or require an account to use the core lenses. Support and feature requests: use the Chrome Web Store support tab.

    Best for: Anyone who feels overwhelmed opening Gmail, deep-work and digital-minimalism fans, people who want a calmer inbox without changing how Gmail works.

    Scrambles visible text in your inbox and email threads using font-based obfuscation, your Gmail looks like gibberish to anyone nearby, but you can still read it. Hold to reveal individual messages when you're ready. After a few days, your brain adapts and you can read scrambled text naturally. Works with Latin and Cyrillic text.
    
    🔍 Zoom Lens
    Enlarges Gmail text to a comfortable reading size (up to 180%) without breaking the layout. Unlike browser zoom, which scales everything - sidebar, buttons, menus - Chameleon Zoom only scales the content you're reading: subject lines, sender names, and message bodies. No horizontal scrolling, no overlapping UI. Your preferred zoom level is saved automatically.
    
    📖 Focus Lens
    Opens emails in a clean reading mode that reduces visual clutter and helps you concentrate on the message content. Ideal for long emails and detailed threads.
    
    How it works
    Chameleon applies visual transformations inside Gmail using CSS and font substitution, entirely within your browser. No email content is collected, stored, or transmitted. All lenses run locally and only change how the page appears on your screen. Your emails and Gmail account are never modified. You can activate one lens or combine multiple lenses at the same time using the floating toolbar that appears in Gmail.
    
    What Chameleon is not
    Not encryption - Privacy Lens provides visual obfuscation, not cryptographic security.
    Not a data collection tool - the extension does not collect or transmit email data.
    Not a Gmail replacement - it simply enhances how you read email.
    
    Permissions
    Storage - saves your lens preferences locally in your browser.
    Access to mail.google.com - required so Chameleon can apply visual lenses inside the Gmail interface.

About

Gmail's font size is too small on laptops, and there is no way to change it. Browser zoom breaks the layout - the sidebar expands, buttons grow, and you scroll horizontally just to read one email. There is no reader mode. The inbox never stops competing for your attention. And there is no way to hide your screen from prying eyes.
Chameleon adds four visual lenses to Gmail. Each one changes how email looks on your screen without changing anything in the email itself. Everything runs locally in your browser - no account, no server, no data collected.

🔍 Increase Font Size - Make Gmail text bigger without breaking the layout

Unlike browser zoom, which scales everything (sidebar, buttons, headers, menus), Chameleon increases only the font size of the content you read. Subject lines, sender names, preview text, and message bodies scale to a comfortable size up to 180%. Gmail's interface stays at its default size. No horizontal scrolling, no oversized sidebar.
Your preferred font size is saved automatically across sessions.
Best for: Laptop users (especially 13-inch screens), anyone over 40, people with low vision, anyone who finds Gmail's default text size too small.

📖 Reader Mode - Read email like a book

Opens any email or thread in a clean, full-screen reading view. Gmail's sidebar, toolbar, and visual clutter disappear. Your message renders in comfortable serif typography, centered in a 68-character column - the same line width used by books and e-readers.
Three themes (light, sepia, dark), a 3-step font size control, and thread-by-thread navigation. Single-keystroke activation. Works on individual emails and full threads.
Best for: Long emails, newsletters, detailed threads, and anyone who struggles to focus in Gmail's default interface. Knowledge workers managing high email volume. People with ADHD or attention difficulties who need fewer visual distractions.

🔒 Visual Privacy - Hide your screen from prying eyes

Scrambles visible text in your inbox and email threads using font-based character substitution. Your Gmail looks like gibberish to anyone nearby. In your inbox, hover over any row to reveal that message; in an open email, hold to reveal text behind a moving window. The eye button instantly reveals or re-scrambles everything in one tap. Turn the lens off entirely whenever you want.
Important: This is visual obfuscation, not cryptographic security. It protects against shoulder surfing - the person sitting next to you in a cafe, train, or open office reading your screen - not a determined attacker with physical access to your device.
Best for: Hide your screen in public. Shoulder surfing prevention for commuters, cafe and coworking-space workers, open-office employees, anyone handling sensitive conversations in shared environments.

🎯 Focus - Quiet the inbox

Dims low-signal inbox rows - promotional, no-reply, and CC'd messages - so the conversations that matter stand out. The inbox stops competing for your attention, without leaving Gmail, switching views, or hiding anything.
Best for: Anyone who feels overwhelmed opening Gmail, deep-work and digital-minimalism fans, people who want a calmer inbox without changing how Gmail works.

🔐 Privacy and trust

Chameleon runs entirely in your browser. There is no server, no data collected, and no email content ever leaves your machine. The extension uses only two permissions: storage (to save your lens preferences locally) and the mail.google.com host permission (required to apply visual lenses inside Gmail). No analytics. No account. No tracking. Manifest V3.

How it works

Chameleon applies visual transformations inside Gmail using CSS and font substitution, entirely within your browser. No email content is modified, stored, or transmitted. All lenses run locally and only change how the page appears on your screen. Activate one lens or combine several from the Chameleon icon in Gmail's toolbar.

What Chameleon is not

Not encryption - Visual Privacy provides visual obfuscation, not cryptographic security.
Not a data collection tool - the extension does not collect or transmit any email data.
Not a Gmail replacement - it changes how you see email, not how Gmail works.

Permissions explained

Storage - saves your lens preferences (active lenses, zoom level, reader theme) locally in your browser.
mail.google.com - required so Chameleon can apply visual lenses inside Gmail. No other sites are accessed.
