Watch English, tap a word
Open any YouTube video or the Shorts feed in oscar. Every English word you do not know yet is marked in the subtitle; one tap pauses the scene and opens the dictionary with the meaning, the forms and an AI explanation of this exact sentence. The dictionary is stored on your phone, so it works offline.
If your app language is not Russian, the lessons explain everything in simple English.
A English Course you can walk
The Course path goes through London, New York, Edinburgh and the Cotswold villages. A three-minute level check sets your start. Voiced scenes, chests and card packs come along the way.
Grammar with Gran
Under the Course street, a lift goes down into the Grammar Depths: one stop per rule, run by Gran, who greets you, grumbles at a mistake and reads every right answer aloud. Pass the final test for a certificate. The stops:
- to be: am, is, are
- Present simple
- there is, there are
- Simple or continuous
- Past simple
- some, any, much, many
- Present perfect or past simple
- a, an, the

Learn any video
Pick a video and oscar finds the words you are missing, then turns them into a short Course stop. The cards it makes replay the moment from the video.
Flashcards that make themselves
One tap saves the word as a card with the screenshot, the audio and the sentence. A built-in spaced-repetition scheduler (FSRS) brings each card back right before you would forget it.
Books, articles and PDFs
Nine classic books in each language are already on the shelf. Add your own texts and PDFs, or point the camera at a paper page.
