Vocab Expander: Learn English is a free Chrome extension developed by Alexey Koval. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension helps users learn new English words using the "Spaced repetition method" and "Associative learning method." With this app, users can improve their vocabulary effectively.

One of the main features of Vocab Expander is that it displays new words from the selected dictionary at the bottom of the page. This allows users to easily access and learn new words while browsing. Additionally, users have the option to create a new dictionary by importing a CSV file.

Please note that currently, only the English-Russian dictionary includes associative images. However, users have the option to attach their own images to new words while in editing mode on the web version of the app.
