What your agent gets

Less time repairing research. More time on the legal workflow.

Cortega improves a model’s legal answer before it is handed to the next step in your application.

MORE RESEARCH DEPTH

Find authorities that fit the question.

Add relevant research when the answer lacks depth or its current authorities are weak.

BETTER-SUPPORTED ANSWERS

Check citations against source material.

Check case identity, references, quotations and whether the cited passage supports the claim.

FEWER REPAIR STEPS

Let your agent continue from stronger input.

Replace weak citations and recheck revisions before returning the answer to your workflow.

Legal source coverage

Checks across cases, legislation, regulations and patents.

Enable the legal sources that match your product’s practice areas.

United States

Case law
Federal and state court decisions
Federal regulations
Code of Federal Regulations
Patent grants
U.S. Patent and Trademark Office

Canada

Federal and provincial law
Legislation and regulations

India

Central and state law
Legislation
Supreme Court
Case citations
Checks include: references resolve against enabled source data. For case citations, checks can compare the case name, citation, pinpoint and quotation with the opinion. Optional claim-support and relevance checks assess whether the cited passage supports the claim and fits the question.

Coverage depends on which sources are enabled and the data loaded for the deployment. Citations outside available coverage can be marked unverified rather than treated as incorrect.

Illustrative example

Improve the research before the agent continues.

Model draft
Question · What legal rule applies?
A concise answer cites an authority that may not support the stated rule.
NEEDS REVIEWClaim support has not been confirmed.
Improved research input
Same model · same application workflow
The revised answer adds relevant authorities, distinguishes the rule, and ties material claims to checked source passages.
SOURCE CHECKEDReferences, quotations and support rechecked before handoff.

Illustrative workflow, not a verbatim benchmark answer or legal advice. The model and research target affect the result.

Measured across models

More research answers reach your agent without inaccurate or fabricated case citations.

Across eight tested LLMs, Cortega increased the number of answers without inaccurate or fabricated case citations. That gives your agent better-supported research to work from.

Why it matters for your product: the benchmark measures citation quality, not overall legal correctness or developer time saved. Better-supported research gives downstream agents less citation repair to do and more useful material for the workflow.

October 2026 benchmark: 100 legal research questions per model; some models returned fewer than 100 answers. “Clean” means no inaccurate or fabricated citations; weak or unchecked citations may remain. Automated checking and judging; no lawyer review. More research may add model calls and tokens. Per-answer cost was not measured. See the complete results, method and limits ↗
