Sideload a language into your day.

To sideload a language is to add a little of it to the reading you already do. The extension swaps selected English words for Spanish words in normal webpages, then keeps the original meaning close enough that the page still makes sense.

That makes it different from scheduled-study apps. There are no streaks to protect, lesson blocks to finish, or flashcards waiting for a separate study session. The practice rides along with your existing browsing.

It also differs from inline-word tools like Toucan. Each language has its own dedicated build, so word choice, difficulty, grammar, mechanism, and launch timing are decided per language — not forced through one generic overlay.

Video tools such as Language Reactor are useful when you are watching subtitled media. Sideload works in the wider web: articles, docs, recipes, forums, and the pages you open without planning to study. Spanish is the first live version; Lithuanian, Chinese, and Japanese are next-language candidates.
