Research & Cite Check

The Research surface in Irys One gives legal professionals three integrated tools:

Case Law Search

Run dual search across U.S. case law:

• Keyword / boolean search — traditional query operators for precise control.
• AI semantic search — natural-language questions the AI converts into relevant results.

Both run in parallel for comprehensive coverage in a single query. Filter by jurisdiction, date range, judge, topic, and more.

Cite Check

Check the citations in a document or research output:

• Existence check — confirms the cited case actually exists (anti-hallucination).
• Format accuracy — validates that the citation string matches the real case.
• Good law status — flags cases that have been overruled, reversed, or otherwise negatively treated.

Cite Check flags hallucinated or stale references for attorney review.

Deep Research

Memo-quality research in one comprehensive pass, run in Workbench's Standard mode:

• Draws on your matter documents, U.S. case law, public web sources, and statutes.
• Synthesizes everything in a single pass and returns a structured report — answer, analysis, aggregated citations, and open questions. There is no iterative loop; that step-by-step investigation is Thorough.
• Citations are aggregated at the end, so the report is copy-ready. Run Cite Check to verify them before you rely on the report.

For a question that turns heavily on case law, Thorough validates citations against source as it works. See the AI Modes overview for how Quick, Standard, and Thorough compare, or the full Deep Research page.
