Lingualeo - Add to dictionary is a free Chrome add-on developed by IvanUl. This add-on falls under the Browsers category and specifically the Add-ons & Tools subcategory.

The main feature of this add-on is that it allows users to easily upload a list of words with translations into their Lingualeo dictionary. Unlike the official add-on, Lingualeo - Add to dictionary enables users to upload multiple words at once.

To upload words, users simply need to copy a list of words from any source or select a list of words on a page. Then, they click on the add-on icon and press the "Add to dictionary" button. The add-on will then display a notification indicating whether the upload was successful or if there was an error.
