What is the Compagnon CAIJ?

The Compagnon CAIJ is an AI-powered legal research tool designed to help you identify the most relevant case law, secondary sources, and legislation in response to your research questions. CAIJ does not use its members’ searches to train its AI systems.

How does the search function work?

Enter your question in plain language in the search bar. Avoid using Boolean operators, strings of keywords, or alternative legal terminology. The Compagnon CAIJ analyzes the meaning of your query and retrieves relevant authorities accordingly. For greater precision, consider breaking down complex questions into several shorter, focused questions. Before displaying results, the Compagnon CAIJ will […]

What are clarification questions for?

The tool may suggest follow-up questions to narrow or refine your query. You may:

What is the AI overview?

The AI overview provides a concise synthesis linking your question to relevant excerpts from case law, secondary sources, and legislation. The overview is based exclusively on documents retrieved from CAIJ’s database, ensuring traceability and significantly reducing the risk of hallucinations. However, as the Compagnon CAIJ relies on generative AI, responses may occasionally be incomplete. Users […]

What types of results will I receive?

The Compagnon CAIJ may provide: Each document is accessible directly through CAIJ.

How are results ranked?

Results are ranked by relevance, based on the substance and intent of your query. Key passages within retrieved documents are highlighted to facilitate review.

How long does a search take?

The relevance analysis and generation of the AI overview may take up to two minutes. We are actively working to reduce processing time.

Can the tool make errors?

Yes. Like any AI-based system, the Compagnon CAIJ may generate errors or incomplete responses. Users must independently verify results and consult the primary sources provided. While the system is designed to rely exclusively on content available within CAIJ’s database, generated responses do not constitute legal advice, a comprehensive legal opinion, or professional consultation. They do […]

Is the content up to date?

The index used by the Compagnon CAIJ is continuously updated with the case law, online secondary sources, and legislation available within CAIJ.

What are the limitations of the Compagnon CAIJ?

The Compagnon CAIJ cannot reliably answer questions based solely on metadata — such as the name of a judge, a specific court, or judicial authorship — nor can it respond accurately to questions concerning very recent legal developments that have not yet generated reported decisions. For example, it cannot reliably respond to: At this time, […]

What is the environmental impact of the CAIJ Companion?

The CAIJ recognizes that tools based on artificial intelligence rely on digital infrastructures that may result in energy consumption. This reality is part of the current challenges associated with the development and responsible use of technology. The CAIJ Compagnon was designed using a measured approach, aimed at optimizing queries and limiting unnecessary uses. By facilitating […]
