Whiteboard to Blackboard (Smart) tekijä Harsh Gupta

Whiteboard to Blackboard (Smart) is a lightweight browser extension designed to reduce eye strain while watching educational videos on YouTube.

Many online classes use bright white backgrounds that can feel harsh on the eyes, especially during long study sessions. This extension transforms whiteboard-style bright backgrounds into a darker, blackboard-style view, making videos more comfortable to watch. At the same time, it intelligently preserves the original colors used by the teacher, so diagrams and explanations remain clear.

The extension works automatically on YouTube videos and is especially useful for students attending online lectures or revision sessions.
