Learn español while you browse

A browser extension that quietly replaces palabras on every page you read. No flashcards, no schedule, no esfuerzo. Just read the web and pick up español along the way.

How it works

The extension runs on every page. You learn by reading what you already read.

🌱

Progressive tiers

Start with the 500 most common words. As you learn them, harder words appear. Five tiers from A1 to C1.

📚

Learn by browsing

Words are replaced inline on pages you already visit. News, Wikipedia, Reddit — it all becomes practice.

🧠

Struggling detection

Seen a word 10 times but never clicked “known”? The extension notices and helps you focus on it.

🚫

No flashcards, ever

No drills, no streaks, no guilt. Just real context. Hover any word to see the original. Click when you know it.

Free now, sync later

The extension is free forever. I am testing demand for cross-device sync before turning it on.

Interested in sync?

Join the mailing list and I’ll use that demand signal to decide whether to ship cross-device sync.

No checkout yet. Just leave your email and I’ll send an update if sync moves from idea to launch.

Powered by Buttondown. No analytics, no checkout flow, just email updates.

Privacy first

We built this the way we’d want it built for ourselves.

🔒

No tracking

No analytics, no telemetry, no fingerprinting. The extension has zero tracking code.

💻

Data stays on your device

Your browsing data never leaves your browser. No URLs, no page content, no history — nothing.

🔐

Sync is planned to be E2E encrypted

If sync launches, the server will store an opaque blob it can’t read. Encryption stays client-side.

Waitlist is lightweight

The current goal is simple demand validation. If you join the waitlist, you are just raising your hand for updates.
