Vocabulary Builder for TOEFL & IELTS

Why Vocabulary Is Critical for TOEFL & IELTS

Both exams test more than memorization. You need to understand academic vocabulary in context, recognize subtle differences between similar words, recall terms under time pressure, and use vocabulary accurately in writing and speaking. Random word lists aren't enough.

Two Smart Ways to Study Vocabulary with Bellek

1) Build Vocabulary from Real English Content

TOEFL and IELTS vocabulary appears naturally in news articles, academic texts, opinion essays, and online learning materials. With Bellek, you can:

Highlight unfamiliar words while reading real English content
See English definitions with synonyms and examples instantly
Get translations into your preferred language (20 languages supported)
Save words with the sentence context and add your own study notes
Organize into collections: "TOEFL Reading," "IELTS Writing," "Academic Core"

This helps you understand how exam vocabulary is actually used — not just what it means in isolation.

2) Study Existing TOEFL & IELTS Word Lists

Already have exam vocabulary lists? Import them via CSV. Bellek auto-detects formats from Anki, Quizlet, and spreadsheets. Combine imported lists with words you save from practice materials, and study everything in one place.
