EPSO
Cutting incoming questions by 70%
EPSO, the European Personnel Selection Office, organises the selection competitions that recruit staff for the European Commission, Parliament, Council, Court of Justice and every other EU institution and agency, attracting tens of thousands of applicants each year across the European Union in 24 official languages.
The Case
Challenge
Answer a high volume of repetitive, procedural candidate and staff questions faster and in 24 languages, without generic AI that drifts from EPSO's published documentation or breaches EU data sovereignty.
Solution
Two source-grounded AI assistants - Knowledge Navigator for internal staff, Trusted Answers for candidates - built on EPSO's existing Drupal platform and EU-hosted infrastructure.
Result
70% fewer incoming questions, cited answers in all 24 EU languages and faster staff onboarding - deployed in under 8 weeks.
Trusted answers at institutional scale.
Dropsolid acted as system integrator, guiding EPSO's internal team to launch two source-grounded AI use cases through a single Drupal administrative interface, all running on EU-sovereign infrastructure aligned with GDPR and the EU AI Act. The result: a 70% reduction in incoming questions reaching the team, verifiable cited answers across 24 EU languages and faster onboarding for new staff - live in under 8 weeks, now moving into public testing with candidates.
