For 25 years, the Wikimedia movement has been constantly innovating to promote the values of free and universal sharing of all human knowledge for the benefit of humanity. In 2026, as we face the challenges of connectivity, misinformation, and the rise of AI, our ability to innovate collectively is more essential than ever.

To address these developments, we are introducing a new program focusing on Team Challenges in the lead-up to Wikimania. This year, we are inviting experts and newcomers to the Wikimedia community to join forces with participants in our Wikimania Hackathon. The idea is not to replace the hackathon format, but to offer a different approach. We want to bring together diverse perspectives and skills by pairing Wikimedians from all walks of life (not just developers!) with professionals from other fields. The goal is to share our best practices and design digital tools that are sustainable, inclusive, and accessible to all.

Next week, we are kicking off our first online orientation sessions training newcomers on wiki tools. In the coming weeks, they will form teams with Wikimedia community members to undertake one of the 2026 challenges. Stay tuned for further updates as the teams work together toward the Team Challenges showcase concurrent with Wikimania Paris. 

We can’t wait to see what the cross-pollination between different disciplines, perspectives, and skill sets will bring. Good luck to all!

10 challenges for maximum impact

The goal is simple: To turn the community’s needs into concrete solutions. We have selected 10 major technical challenges that address the complex issues encountered on a daily basis across Wikimedia projects. 

These challenges are based on the three pillars of Wikimania 2026:

• FREEDOM: Ensuring the interoperability of free software to facilitate its reuse and maintenance, and to guarantee its long-term viability.
• EQUITY: Promoting multilingualism. Designing tools capable of overcoming language barriers to bridge gaps in sources and contributions on a global scale.
• RELIABILITY: Developing AI-based detection tools to assist volunteer moderators in their work of verifying and protecting information.

Discover the 10 Challenges
	Fix the sources Automatically detect outdated, retracted or broken sources in articles, and facilitate their updating or archiving.
	Welcoming newcomers Reinvent how we onboard newcomers through chatbots, guided micro-edits, and gamification lower the barrier to entry on wikis.
	Update the obsolete Identify and flag outdated articles, obsolete illustrations and screenshots, and outdated graphics to: encourage the community to update them.
	Boost multimedia experience Enhance the audiovisual experience on wikis: playlists on Commons, a modernised video player, annotation of audio segments, and games focused on accents and pronunciations.
	Deciphering biases Develop tools to detect gender, geographic, and cultural biases in Wikimedia content to: encourage the community to correct them.
	Gamify knowledge Create serious games and playful experiences using Wikimedia data to: learn, contribute, and explore in new ways.
	Stream data with Wikidata Take advantage of Wikidata content to: generate lists, tables or up-to-date visualisations, semi-automatically, for other projects in the Wikimedia galaxy or further.
	The editor of the future Improve the editing experience: search & replace in the source editor, a standardized citation toolbar, a better visual table editor, and text alignment in VisualEditor to modernise and streamline contributions.
	Explore knowledge Design and experiment new ways of sharing knowledge, in interactive and visual ways…for the modern web!
	Connect multilingual knowledge Facilitate translation, the reuse of content across Wikimedia projects, and collaboration with other Open Source projects so that knowledge can flow freely in all languages.
