Tradelingo — Learn Constr

TradeLingo turns your browser into a Spanish classroom — without interrupting your day.

Every time you browse the web, TradeLingo quietly replaces English words with their Spanish equivalents right on the page. News articles, safety manuals, product specs, how-to guides — it all becomes a living vocabulary lesson. No flashcards. No separate app. Just your normal browsing with a Spanish twist.

WHO IT'S BUILT FOR
──────────────────────────────

TradeLingo is designed for construction workers, tradespeople, and anyone working on bilingual jobsites. If you're a framer working alongside Spanish-speaking colleagues, a foreman who wants to communicate safety instructions clearly, or an apprentice learning the trade — this extension speaks your language.

The vocabulary is construction-first: ladder, scaffold, concrete, wire, drill, hammer, beam, foundation, crane, plumbing, drywall, and dozens more jobsite terms are built right into the free plan.

HOW IT WORKS
──────────────────────────────

1. Install the extension and toggle it on.
2. Browse any website as you normally would.
3. A percentage of English words are replaced with Spanish — you control how many.
4. Hover over any replaced word to see the original English in a tooltip.
5. A small "TL" badge in the corner shows how many words were replaced on the current page.

The replacement level slider lets you go from a light touch (5% — just a few words here and there) all the way to full immersion (80% — nearly every eligible word replaced). Start low and dial it up as your vocabulary grows.
