Lingosu
Language learning, in your browser

Read the web. Pick up a language without trying.

Lingosu swaps a few words on every page for the language you are learning, says them aloud in a natural voice, and turns them into short lessons, games and daily challenges.

Free to start. No account needed.

Tap a highlighted word.

How it works

Three steps, and the second one happens by itself.

1

Pick your language

Choose what you speak and what you want to learn. Set how many words you want to see.

2

Keep browsing

Words on the pages you already read are swapped in context. Hover to see the meaning, tap to hear it.

3

Play and practise

Save words, take short lessons, and finish a daily challenge to keep your streak going.

Inline learning

Words appear where you are already reading.

No new app to open. Lingosu works inside the pages you visit, and a small card gives you the meaning, an example and a way to save the word.

Voices

Hear every word the way it is said.

Choose from ten natural voices. Slow a word down, or hear it spelled letter by letter in the voice you picked.
