When does the next train to Munich leave?
Duolingo put on 40 pounds of gamification. Babbel started charging by the lesson.
There had to be a better way.
You've never heard of the FSI course? That's the point. It's not a consumer product. It's what serious language learners have quietly used for decades because it actually works. We took it, cleaned it up, and built a modern app around it.
No streaks. No owls. No premium locks on the good stuff. Just you, native audio, and a proven structure that gets you to real German.
Start learning for free →Every unit opens with a native-speaker dialogue. No phonetic guides. No translation crutch. You listen first, just like a child does — then we explain what you heard. Your ear develops an authentic accent before your brain has time to overthink it.
Over 1,000 hours of original FSI recordings. Real German, from real speakers, in real situations.
FSI's substitution drills are legendary for a reason. Instead of memorizing grammar rules, you repeat variations of a sentence until the pattern lives in your muscle memory. It's boring in the best possible way.
"Der Mann kauft ein Buch." Then "Die Frau kauft ein Buch." Then "Die Frau kauft eine Zeitung." Six minutes of that and the accusative case just sticks.
Spaced repetition surfaces vocabulary and phrases right before you'd lose them. Not random flashcards — a schedule built from your actual performance. Words you know well come back rarely. Words you struggle with come back constantly.
It sounds simple. It works unreasonably well.
The Foreign Service Institute developed this course for US State Department diplomats in the 1960s. The goal: take someone with no German to professional working proficiency, fast. The audio-lingual method they invented worked then. It works now.
Every single lesson, every drill, every dialogue in DeTawk follows the original 120-unit FSI sequence. We didn't reinvent it. We just made it not look like a government document from 1961.
$9/month when beta ends. Early members lock in this price forever.

Because it works. The FSI course has been producing genuinely fluent German speakers since the 1960s. The audio-lingual method — hear, repeat, drill — builds language intuition rather than vocabulary lists. Everything else we've tried is downstream of this method.
Duolingo is optimised for daily active users, not for language acquisition. Streaks, XP, leaderboards — these are engagement mechanics, not learning mechanics. DeTawk is optimised for one thing: you actually speaking German. No streaks. No hearts. No owl.
The original FSI materials are public domain — produced by the US government and freely available. DeTawk's app, platform, spaced repetition engine, and UX are what you're paying for. Think of it like paying for Spotify when the music already exists.
FSI estimates ~750 hours of study to reach B2/C1 proficiency. At 30 minutes a day, that's about four years. At the FSI's classroom pace (full-time immersion), it's 30 weeks. The structure is all there — you just follow it.
Paid plans start at $9/month. Members who join during beta lock in that price forever — even if we raise it later. Free accounts stay free, with the first 10 units and 1,000 vocabulary items always accessible.
Yes. DeTawk is fully mobile-optimised. Audio lessons, drills, and spaced repetition all work on any device. A native mobile app is on the roadmap.
A note from the founder
I spent two years trying to learn German. Duolingo kept me busy. Babbel kept me spending. Neither got me speaking. Then I stumbled on the FSI course — the same one the State Department uses to produce actual diplomats — and it clicked within weeks. I couldn't understand why no one had built a real app around it.
So I built DeTawk. It's opinionated. It doesn't celebrate streaks or sell you premium grammar packs. It just puts the best German curriculum ever made in a clean interface and gets out of your way. If you have feedback or want to say hello, email me directly at hello@detawk.com. I read everything.
If you've ever wanted to actually learn German — not collect badges, not keep a streak alive — this is built for you.
