Explainable Autofill for Trustworthy Surveys
Two AI co-pilots that respect your data: one helps you design better questionnaires, the other helps respondents answer them with cited evidence from their own documents.
Built by researchers. Made for institutions. Developed in the EU.
What it is
EXPATS pairs a survey response assistant with a survey design assistant. Both run on the same privacy-first foundation, and both explain their reasoning instead of asking you to trust a black box.
Answer with evidence, not guesswork. Cue reads documents you upload, retrieves the relevant passages, drafts a concise answer, and cites exactly where each part came from.
Design better questionnaires, faster. Shape suggests and rewords questions, checks them against style and consistency rules, proposes tags, and imports or exports surveys in standard formats.
What it does
EXPATS is a focused proof-of-concept. Being transparent about its limitations is part of being trustworthy, so here is the line, in both directions.
Design principles
A few key decisions have shaped this project. We trade flashiness for trust, portability and a code base that remains simple enough to audit.
Session-based isolation and automatic TTL cleanup. No profiling, no cross-session tracking — privacy is the default, not a setting.
Every suggestion carries its citations, and each session produces an audit report. You can always see why the system proposed what it did.
Four available platform adapters and an SDK-first REST API, so EXPATS slots into existing survey tools instead of demanding new ones.
One Docker Compose stack, bundled Keycloak for login, and bring-your-own LLM key. Run the whole thing inside your own walls.
Roadmap
EXPATS runs a pilot from January to May 2026 with Hogeschool PXL and partner institutions, demos at GÉANT TNC in June 2026, and reports out by the end of June 2026.
Shared infrastructure, document processing & vector search, the Cue and Shape assistants, and a browser-based UI for each — all built and tested.
Deployment to pilot partners, real-user testing, and collecting metrics on authoring time, response time and citation accuracy.
Live demo at GÉANT TNC (June 2026), final evaluation report (June 2026) and the open-source release for the GÉANT community.
Specced and waiting, to revisit after pilot feedback:
