Toucan: Duolingo as a Chrome plugin via contextual learning
Toucan is a Chrome extension that swaps a handful of words on every article you read into the language you want to learn, so you absorb a language while browsing instead of opening a separate app.
“It's called Toucan and it's basically the really dumbed down version is it's like Duolingo, which is a language learning website, but it's a Chrome plugin and it changes a handful of words of every article that you're reading into the language that you wanna learn. So it's contextual learning.”

Framework
Kill the 'separate activity' to beat user friction
Shaan argues the real barrier to habits like learning a language isn't difficulty — it's the friction of starting a separate activity. Toucan wins by shifting a few words on pages you're already browsing, so learning happens passively without a dedicated session.
“And the biggest friction is not that it's that hard to learn a language. It's hard to make the time to like sit down, open the book or download the app, open the app and focus and just do Duolingo for 30 minutes a day. Um, it doesn't sound that hard, but in practice it's like, it's a separate thing to do. What I think is super smart about what Toucan is doing is you don't have to make it a separate thing.”
