Question 1

Is Octalingo really free?

Accepted Answer

Yes. The free plan lasts forever: save unlimited vocabulary, use flashcards and spaced-repetition review, the book reader with tap-to-translate, collections, daily streaks and the word of the day. You only upgrade if you want unlimited AI-powered features.

Question 2

How does it turn a YouTube video into a lesson?

Accepted Answer

Paste any YouTube link and Octalingo extracts the key vocabulary, phrases and grammar from the video, then builds interactive exercises from them in seconds. The new words go straight into your personal library.

Question 3

What levels does it work for?

Accepted Answer

Every level, from absolute beginner (A1) to advanced (C2). Exercises, the word of the day and suggested content all adapt to the level you set, and you can change it any time.

Question 4

Do I have to find my own content?

Accepted Answer

You can, and that is the magic, because you learn from videos and books you actually enjoy. But you do not have to: there is a Discover library of lessons made by other learners you can start from right away.

Question 5

How is this different from Duolingo or Anki?

Accepted Answer

Instead of a fixed course or flashcards you build by hand, Octalingo creates exercises from your own words and the real content you choose. You practise the language you actually want to use, not a generic word list someone else picked.

Question 6

Can I use it on my phone?

Accepted Answer

Yes. Octalingo works on any device through your browser and installs to your home screen like an app, so you can learn anywhere. Native app versions are on the way.

Question 7

Can I cancel any time?

Accepted Answer

Any time, in a couple of clicks. And if you stop, you keep the free plan forever, with your vocabulary and progress exactly where you left them.
