GlossX for Safari

Replace Chinese text on web pages with natural English for passive learning

Problem

A developer noticed that embedding English into Chinese web pages helps users passively absorb English. But the Safari version of a similar extension didn't exist, so he built his own. This suggests an unmet need on a specific browser with a user willing to code it themselves.

Solution

A Safari extension that replaces Chinese phrases on web pages with natural English translations, plus a word/sentence collection and review feature. It supports site whitelisting, difficulty tiers, and hover-to-see-original, letting users encounter English during natural reading.

Users

Mac/iOS Safari users who want passive English immersion while browsing
