Zappy

You're reading a Japanese tech article. A Chinese market report. A Spanish news piece.

You highlight the key paragraph. Zappy translates it — right there, on the page, in
one second. No new tabs. No copy-pasting. No Google Translate popup.

What makes Zappy different

Most translation extensions route your text through their servers. You pay a subscription.
You trust them with your data.

Zappy works differently. You connect your own AI provider key — DeepSeek, OpenAI, or
any compatible API. Your text goes directly from your browser to your provider.
Zappy sits in the middle for less than a second and gets out of the way.

No subscription. No markup. You pay only what your API provider charges.

What Zappy does

Select any text on any webpage → translation appears instantly in a popup.

Save translations as bookmarks — build your personal library from foreign-language sources.

Works on every website: news sites, research papers, social media, PDFs opened in Chrome.

Supports any language your AI provider handles — Japanese, Chinese, Korean, Arabic, Spanish,
and more.
