Octalingo: Learn Languages

Octalingo turns whatever you're reading, watching or curious about into
language practice built from your own words.

ANYTHING BECOMES A LESSON
Paste a video, an article, a photo or just a topic. Octalingo pulls out the
useful vocabulary, phrases and grammar, then turns them into exercises in
seconds.

A VOCABULARY LIBRARY THAT'S ACTUALLY YOURS
Save any word or phrase as you meet it. Highlight text anywhere in the app for
an instant translation, and save it with one tap. Every word moves from saved
to learning to familiar to mastered, with spaced repetition deciding when you
see it again.

PRACTICE MADE FROM YOUR WORDS
Fill-gap, conjugation, translation and multiple-choice exercises, generated
from the vocabulary you've actually saved — not a generic list.

WRITE AND GET FEEDBACK
Write in the language you're learning and get detailed feedback on grammar,
naturalness and word choice.

READ YOUR WORDS IN CONTEXT
Turn a set of your saved words into a short story you can actually read, so
they stick in context instead of on a flashcard.

ORGANISE AND TRACK
Group words into collections by topic, country or level, then generate a whole
exercise set from any collection. Watch your vocabulary climb through mastery
levels, day by day.
