Xayn Launches Web Version of Its Private Search and Discovery Engine

Xayn WebBeta transfers the essence of the privacy-protecting app to the desktop

  • Launched in December 2020 as a mobile app, Xayn has been downloaded more than 250,000 times worldwide
  • Xayn WebBeta enables desktop users to actively search for information online or browse through the personalised discovery feed with full privacy-protection
  • The Berlin-based company just received 10 million EURO in Series A funding

Berlin, 30 August 2021 – The Berlin-based AI company launches today Xayn WebBeta, a light web version of its private search and discovery browser which was launched in December 2020 as a mobile app. Xayn WebBeta brings the privacy-protecting search and its discovery feed now also to desktop users so that they can find and dive deeper into new information online.

The Xayn mobile app has already been downloaded more than 250,000 times worldwide. The team with 30% PhDs now transferred the essence of its mobile app to desktop focusing first on Chromium-based browsers (e.g., Chrome with 68,5% global market share) and Firefox (7,62% of global market share). To enjoy a private, ad-free browsing and searching experience on their desktop, users can simply go to the company’s website: search.xayn.com  

“We started Xayn as a direct response to the false privacy vs. convenience dilemma and quickly proved that it’s possible to solve this trade-off so users are no longer losers. In fact, with each update, our fantastic team of engineers and designers demonstrates all over again how privacy, quality, and great UX go hand in hand,” said Leif-Nissen Lundbæk, Co-Founder and CEO of Xayn. “We didn’t want to copy what's already out there, but instead re-think it and create something new. With Xayn, you can find your favourite part of the Internet – either by actively searching the web or by browsing through the discovery feed that offers personalised content suggestions from the entire Internet. Either way, your privacy is always protected.”

Both versions of Xayn use Masked Federated Learning to protect users’ data privacy while still providing them with an individually tailored web experience. They are created with the same code base in Flutter, a developing framework that's designed to function both on mobile and web. The team transferred the AI to work directly in the respective browsers with high speed via WebAssembly so that all personal data stays privately within the browsers. Therefore, the light web version functions similar to the app and also protects users’ data privacy by leaving all personal data on the devices while training the AI models locally. For first time users, the AI models get downloaded to the respective users’ browsers.  

The core features of Xayn WebBeta include:

  • Personalised search results: Based on past searches and behaviour, users receive highly personalised and, therefore, relevant results for their web searches.
  • Deep search: Enables users to dive deeper into a topic by a simple click and assemble their personal reference library of relevant content.
  • Discovery feed: Offers users a personalised feed of the entire Internet which learns from their Tinder-like swipes. Based on users’ interactions the AI suggests content as a starting point for diving deeper into the riches of the Internet – e.g., an article about a complex topic such as the climate crisis that catches the users’ attention and leads them to start their research using the deep search feature.
  • Powerful and private AI: Trains and learns directly on users’ devices to deliver personalised content suggestions and search results, without collecting or sharing personal data. With its privacy by design approach, Xayn doesn’t track any user data.  
  • Collections: Uses can collect and store their favourite web content by creating, filling, and managing collections.  
  • Noise-free: Eliminates distracting Internet noise by being ad-free, blocking ads on third-party sites, and offering a clean reader mode.

“In creating Xayn’s web version, we have taken all the elements that made the app great and adapted them to the desktop browser window,” said Julia Hintz, Head of Design at Xayn. “The privacy-protecting algorithms, the intuitive design, and the smooth animations have found their way into the web version. Users can switch effortless between mobile and desktop without leaving their familiar environment. This is key for the seamless, deep interaction experience that makes Xayn special.”

To stress the importance of ethical and transparent AI, the company that started as a research project at The University of Oxford and Imperial College London open-sourced the search algorithmics of the Xayn AI. Following its 10 million EURO Series A investment round and the growth of its C-Suite, the company continues product development and expands into the Asian market. Xayn also plans to widen the range of its privacy-first discovery offerings: In the future, users will be able to synchronize Xayn across multiple devices in a privacy-protecting way so that they can transfer the AI’s learnings between their mobile and desktop versions seamlessly without Xayn seeing any of the user data.
