European search engines Qwant and Ecosia said on Wednesday that they have both started serving search queries through an index they developed together, Staan, which aims to be a cheaper, more privacy-focused alternative to Google and Bing.

Last year, French privacy-focused search engine Qwant struck a joint venture with German non-profit search engine Ecosia, to develop a European search index. Called European Search Perspective (EUSP), the JV now aims to serve around 50% of French queries and 33% of German queries by the end of the year.

Qwant said it is using the new index to power some of its features, like AI summaries for search, and Ecosia has plans to add some AI features soon to its platform, too.

EUSP is also in talks with companies to spur the adoption of its index for enabling search within apps. Notably, it is targeting chatbots, presenting Staan as a cheaper alternative to Google and Bing.

“If you’re using ChatGPT or any other AI chatbot, they all do knowledge grounding with web search […] our index can power deep research and AI summary features. Google and Bing’s solutions are also pricey, and our index can offer power search features at a tenth of the cost,” Christian Kroll, CEO of Ecosia, told TechCrunch.

EUSP, like Proton, is pushing to develop a European tech stack that doesn’t rely on technology from the U.S. or China.

“The timing could not be more urgent. The outcome of the 2024 U.S. election has reminded European policymakers and innovators just how exposed Europe remains when it comes to core digital infrastructure. Much of Europe’s search, cloud, and AI layers are built on American Big Tech stacks, putting entire sectors – from journalism to climate tech – at the mercy of political or commercial agendas,” the companies said in a statement.

Kroll added that through this index, combined with European privacy laws, EUSP can offer a more privacy-friendly search solution as compared to its U.S. counterparts.
