Features & Capabilities

Duolingo Dark Mode is a Chrome extension that brings the beloved dark mode feature of Duolingo's mobile apps directly to the web version. Unlike generic dark mode add-ons that can distort visuals or disrupt site elements, this extension carefully styles every part of the Duolingo website for an optimal viewing experience.

Perfect for users who prefer learning in low-light environments or want to reduce eye strain, Duolingo Dark Mode enhances usability while preserving the platform's original design. Though still in development and occasionally imperfect, it steadily improves to provide a seamless dark-themed interface for language learners online.

Is Duolingo Dark Mode Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Duolingo Dark Mode requires a few sensitive permissions. Exercise caution before installing.
