Ulysses — Brazil's Chamber of Deputies institutional AI programme for legislative data and staff support

Brazil's Chamber of Deputies (Câmara dos Deputados) launched Ulysses in November 2018 — a set of AI algorithms, built by the Chamber's Directorate of Innovation and Information Technology (Ditec), that automatically articulates and organises legislative data across the Chamber's portal and internal systems. The tool is named after Ulysses Guimarães, president of Brazil's 1987-88 Constituent Assembly.

Automate and organise legislative-data workflows, and from 2019 automatically distribute incoming parliamentary information requests across subject-matter knowledge areas to reduce the manual effort previously needed to triage this repetitive workload.

From 2019, the Chamber's Legislative Consulting office (Conle) put Ulysses to operational use, distributing incoming information requests among 22 subject-matter knowledge areas, trained on roughly 300,000 historical requests logged since 2003. On 11 December 2025, Chamber President Hugo Motta relaunched Ulysses as a formal institutional AI programme alongside newly published AI-Governance and Data-Governance policies; staff gained sanctioned access to Claude, Gemini and GPT, and the Chamber announced an internal assistant, 'Ulysses Chat', plus planned features to route bills to committees and flag potential constitutional conflicts. The Chamber also co-leads, with the European Parliament, a 14-chamber collaborative under the Inter-Parliamentary Union's Centre for Innovation in Parliament, which published shared AI-governance guidelines for parliaments worldwide in December 2024.

Ulysses has been in continuous operational use since 2019, automatically distributing real parliamentary information requests; the Chamber reports this reduced the manual effort previously required for triage, though no independent quantitative evaluation of time or error savings was found.

Secretary-General Lucas Ribeiro stressed that human review applies at every stage of AI-assisted work. The programme has grown from a single 2018 tool into an institution-wide effort with both domestic policy weight and an international governance-leadership role.
