The reading-level problem

It is hard to know whether an English book is too easy, too hard, or just right.

Learners often choose books by title, reputation, or recommendations. That can work, but a famous classic can still be too difficult today, and a familiar story can hide dense vocabulary.

TeakReader makes the decision more concrete by connecting reading readiness to your known words, unknown words, CEFR vocabulary, and chapter-level stats.

Vocabulary shape

See the CEFR shape of the vocabulary before you study.

TeakReader can show A1-C2 vocabulary distribution, top unknown words, and Known, Learning, Ignored, and Unknown states for processed books and subtitle sets.

This is not an official CEFR test. It is a practical reading signal that helps you choose material and decide what to review next.

Chapter readiness

Check chapter comprehension before you start reading.

A whole book can feel intimidating, but chapter-level stats make the next step smaller. TeakReader can show comprehension, unknown counts, and Study buttons so you can choose an easy win or prepare for a harder section.

What the signal helps you decide

Pick the next book or chapter with less guesswork.

Reading level is not only a label like beginner, intermediate, or advanced. It depends on the words you already know and the words that appear often in the material you picked.

Too easy

Known vocabulary dominates and the chapter may be better for relaxed reading than focused study.

Readable challenge

Most words are familiar, with enough unknown vocabulary to make the chapter worth studying.

Too hard today

Unknown words appear often enough that a short study session first may make reading smoother.

Books, movies, and TV

Use the same reading-readiness signal across books and subtitles.

TeakReader tracks vocabulary across EPUB books, Project Gutenberg classics, movies, and TV subtitles. A word learned while reading can make subtitle vocabulary easier later, and subtitle study can help a future chapter feel more readable.

Personal vocabulary memory

Your reading signal changes as your vocabulary grows.

Known, Learning, and Ignored decisions affect future stats. The more you read and review, the more useful TeakReader's unknown-word and comprehension signals can become.

Study what matters next

Turn reading-level signals into a study session.

Once TeakReader surfaces top unknown words or a chapter Study button, you can review vocabulary from the material itself. That is more useful than starting with a blank deck or a generic list.

CEFR guardrail

CEFR stats are a reading aid, not a certificate.

TeakReader can classify and display vocabulary by CEFR levels, but it is not an official CEFR exam, placement test, or certificate. The point is practical: choose material, spot unknown words, and study before the book becomes frustrating.
