About this extension

When WritteN ? (WWN) is a browser extension that displays how old the information in a Wikipedia article is. Inspired by the Who Wrote That (WWT) extension, it highlights information using a colour gradient. The aim is to make it easy to spot the oldest information, in order to gauge how up-to-date an article is, or even whether it needs updating.
This extension was developed as part of Wikimania Paris 2026 by Team Challenges Europe 03F Zéfirottes, in response to the ‘Update the Obsolete’ challenge.
