ExplalexEnglish through series, films and books
Explalex analyses a series, film, book, YouTube video or web article and shows exactly which vocabulary and grammar that material requires. You study the words you will meet tonight instead of an abstract list from a textbook.

"Run" meaning "to move fast" and "run" meaning "to manage a company" are two separate skills. Explalex tracks your vocabulary and progress per sense, so your level is never inflated by words you only know in one meaning.
Before you press play you can see how much of the vocabulary and grammar you already know and how many senses are still missing. Pick something you can actually finish instead of giving up ten minutes in.
Coverage is not only about words. Grammar constructions and connected speech are counted too — the reason a sentence you can read easily still falls apart when you hear it.
Intervals, statuses and the review queue are computed on the server, not on the device. Your progress is identical in the browser and on iPhone, even after an offline session.
Besides the built-in catalogue you can paste your own link — an article, a video or a book. Explalex parses it and builds lessons from it.
Explalex never stores or displays rights-holders’ text or video. We work only with our own study data — the dictionary, definitions, explanations and statistics — while you open the material itself at the original source.
A short placement test estimates your vocabulary and grammar. You can skip it and let the level settle as you study.
Choose a series, book, video or article from the catalogue, or add your own link. Coverage and the list of unknown senses appear immediately.
Explalex assembles a lesson from the senses and rules that occur in this particular material and chooses an exercise type for each of them.
After you watch, what you learned enters spaced repetition and the coverage of everything else is recalculated.
There is a free plan with a daily cap on new senses and a limit on materials. A Plus trial starts at sign-up and needs no card. Plus removes the limits.
Explalex does not give access to films, series or books and stores no copies of them. It works with study data about a material; you watch or read the material wherever you legally have it.
Yes. Paste a link to an article, a YouTube video or a book and Explalex will parse it and build a dictionary, a coverage estimate and lessons from it.
A CEFR level describes you in general; coverage describes one specific material. The same B1 learner may know 95% of a sitcom and 60% of a medical drama. Explalex computes that number per material.
Yes, there is an iOS client. Progress, vocabulary and the review queue are shared with the web version, and offline sessions sync on the next connection.
It is how words change in fluent speech: neighbouring words merge, sounds drop and reduce. That is why a phrase you can read is unrecognisable by ear. Explalex accounts for it when estimating whether a material is within your reach.
Sign up, take the short placement test and look at the coverage of your first material — it takes a few minutes.
