Mojikae by sakuyasann

<p>Mojikae temporarily replaces the fonts on the page you are viewing with Google Fonts, so you can compare typefaces in the real interface instead of a mockup. Useful when picking type for a SaaS product, an admin dashboard, or a website.</p>

<p><b>What it does</b></p>
<ul>
<li>Detects the font-family values actually in use on the page and lists them</li>
<li>Override the whole page, or just one specific font-family</li>
<li><b>Combine a Latin face with a Japanese one</b> (for example Playfair Display for Latin, Zen Maru Gothic for Japanese)</li>
<li>Every search result is rendered in its own typeface</li>
<li>Filter by language (Japanese, Cyrillic, Greek, and more) and by category (serif, sans-serif, monospace, and more)</li>
<li>Over 1,900 Google Fonts, sorted by popularity</li>
<li>Save font combinations as presets</li>
</ul>

<p><b>Built to stay out of the way</b></p>
<ul>
<li>Changes apply <b>only to the tab where you clicked the toolbar icon</b> and are <b>fully reverted on reload</b>. Nothing on the page is modified permanently.</li>
<li>Icon fonts (Material Symbols, Font Awesome, and similar) and monospaced code blocks are detected and left untouched.</li>
<li>Requires only activeTab, scripting, storage, and the Google Fonts domains. It never requests access to all sites.</li>
<li>No browsing history, URLs, or page content is collected or transmitted. Only recently used font names and your presets are stored locally.</li>
</ul>

<p><b>How to use it</b></p>
<ol>
<li>Open the page you want to test and click the Mojikae toolbar icon</li>
<li>Choose what to override — the whole page by default, or a specific detected font-family</li>
<li>Search and pick fonts. With two or more selected, the first covers Latin and the rest act as fallbacks for Japanese and other scripts</li>
<li>Click Apply, then Release or simply reload to restore the original</li>
</ol>
