Case Study: ESA improves space data access and user experience with Tilde’s EVA virtual assistant

ESA improves space data navigation with Tilde across 1 billion+ catalogue sources

The European Space Agency (ESA) faced a challenge with users struggling to navigate its complex, data-rich science portals. To improve user interaction and provide 24/7 assistance, ESA required a flexible AI platform to build customized virtual assistants. They partnered with language technology vendor Tilde to develop this solution.

Tilde developed the EVA (ESA Virtual Assistant) platform, a conversational AI integrated into the public ESASky portal. EVA provides accurate, contextually relevant answers and enables advanced task automation and voice command processing for an inclusive experience. The solution significantly improved user interaction and made the portals more accessible for professional astronomers and space enthusiasts alike. Tilde's work has streamlined how users find and explore celestial data.
