Registries of Artificial Intelligence Use Cases
Prepared by Dr. Piyush Mathur exclusively for Thoughtfox, this growing list of registries of Artificial Intelligence (AI) use cases is hereby launched on January 28, 2026. Currently, the list is alphabetical only; it provides the URLs for the registries and mentions the best-verified date on which a registry would have gone online. Visitors to the list are welcome to send any suggestions to expand, improve it via this contact form. Visitors may also want to read the following document ahead of surveying the list:
‘Algorithmic Transparency in the Public Sector: A State of the Art Report of Algorithmic Transparency Instruments’ (OECD, 2024)
Asia
China: National Algorithm Filings, Office of the Central Cyberspace Affairs Commission (CAC): https://www.cac.gov.cn/
Went online / first public filings in August 2022—after the Internet Service Algorithm filing rules came into force.
Note: China’s approach is a mandatory filing/registration for certain ‘internet information service algorithms’ under the CAC rules.
Europe
Amsterdam (City of Amsterdam): https://algoritmeregister.amsterdam.nl/en/ai-register/
Went online 28 Sep 2020; launch announced, jointly with Helsinki, at the Next Generation Internet Summit.
Note: One of the world’s first municipal AI/algorithm registers (beta at launch).
Basque Country / Euskadi (Spain); regional (autonomous community) register: Catálogo de algoritmos y sistemas de IA (Catalogue of AI algorithms and systems):
https://www.euskadi.eus/catalogo-de-algoritmos-y-sistemas-de-ia/web01-a3kebarg/eu/#
Initiated by Consejo de Gobierno Vasco (the Basque Government) as part of its Data Governance Strategy, launched on December 19, 2023; the AI register was launched in January 2025, publicly reported on January 11, 2025: https://www.euskadi.eus/que-es-el-catalogo-de-algoritmos-y-sistemas-de-ia/web01-a2data/es/
Note: Regional (autonomous) public catalogue of algorithms used by the Basque public administration.
France: Observatoire des Algorithmes Publics (ODAP), national / citizen observatory & inventory
Registry / observatory URL: https://odap.fr/
The ODAP inventory dataset: https://www.data.gouv.fr/datasets/inventaire-des-algorithmes-publics-de-lodap/
Went online (first public inventory version) in November 2024; ODAP’s first public edition of the inventory / site first rolled out in late 2024). ([Labo][5])
Note: ODAP is a civil-society / observatory project that compiles an inventory of algorithms used by central administrations (different from a government-run mandatory register but publicly available).
Helsinki (City of Helsinki): https://ai.hel.fi/en/ai-register/
Went online on 28 Sep 2020; launch announced alongside Amsterdam at the Next Generation Internet Summit.
Provides descriptions of AI systems used by the city and was among the earliest municipal registers.
Netherlands (national Algorithm Register): https://algoritmes.overheid.nl English dashboard: https://algoritmes.overheid.nl/en/dashboard
Went online (first public version): 21 Dec 2022; (first public release / announcement).
Note: National government register listing algorithms used by government organisations; first version launched Dec 2022.
Norway: *national public-sector AI overview (Data.norge)
Registry / catalogue URL: https://data.norge.no/kunstig-intelligens
Went online (page accessible / cited) by at least 15 Jan 2024 (cited in OECD / national reports — exact project “launch” date not strongly signalled on the page).
Note: This is an official national data-portal catalogue (‘Kunstig intelligens – oversikt over prosjekter i offentlig sektor’) providing an overview of public-sector AI projects.
United Kingdom: Algorithmic Transparency Records (ATRS) / public register
Registry URL: https://www.gov.uk/algorithmic-transparency-records
Went online / ATRS published: 29 Nov 2021 (Algorithmic Transparency Recording Standard published Nov 2021; the gov.uk records page is the public listing).
Note: ATRS provides a standard and public repository for algorithmic transparency records; compliance by departments has at times been limited.
North America
Canada (Federal government’s AI systems’ tracker): https://open.canada.ca/data/en/dataset/fcbc0200-79ba-4fa4-94a6-00e32facea6b/resource/369f6f34-148a-42ed-b581-8c164e941a89
The Government of Canada AI Register (GC AI Register) was announced on November 28, 2025 on the website of the Treasury Board of Canada Secretariat (TBCS).

United States (federated agency AI use-case inventories or federal)
Consolidated federal reference page / guidance: https://www.cio.gov/policies-and-priorities/Executive-Order-13960-AI-Use-Case-Inventories-Reference/
Executive Order 13960 (Dec 3, 2020) established the federal requirement for agency AI use-case inventories; consolidated public inventories and the Federal repository were published/compiled in later years (consolidated repo activity visible in December 2024
Note: The U.S. approach is federated, i.e., agencies publish their own inventories under EO 13960 rather than a single central registry listing every federal AI system. Representative agency inventories would be the Department of Homeland Security’s (DHS) AI Use Case Inventory https://www.dhs.gov/publication/ai-use-case-inventory-library or Health & Human Services’ (HHS) counterpart https://www.hhs.gov/programs/topic-sites/ai/use-cases/index.html
