Quality built into governance
Identify weak arguments and unsupported claims.
You need specific evidence and useful criticism, not agreement with your premise. Cortega checks for missing work, unsupported claims and weak citations, and presents the points that need your attention. You choose the task, review the evidence and decide what goes into the final work.
- 01 / Research
Build the evidence
Read the matter documents and use connected research sources. Keep the passages behind each point.
- 02 / Draft
Compare approaches
Where enabled, independent drafts surface different points. A merge brings the supported work together.
- 03 / Review
Challenge the answer
A separate review checks for omissions and incomplete work. Models can take different roles through Cortega’s governed routes.
- 04 / Verify
Inspect the support
Check document quotations and available citation records. Show missing evidence and verification status for the lawyer’s review.
Explanatory workflow. Checks and research sources depend on the tool and configuration; a source match does not establish a legal conclusion.
What makes the research deep?
The workflow reads the underlying file, follows relevant sources through connected research tools, compares competing positions and reviews what the draft leaves out. Research access depends on the practice’s connectors. Unavailable sources and unresolved authority checks remain visible.
Measured results
Cortega met 91.4% of benchmark criteria.
The October 2026 evaluation covered 1,743 public Harvey LAB tasks. The score measures the Cortega workflow against the task rubrics.
Source checks and revision help identify material that needs attention. The benchmark did not measure lawyer time saved; a practice pilot should measure total time through final review.

How to read the sample results
These are actual application views using invented sample documents. Results are research aids for a lawyer to review. Authorities are labelled with their verification status. Document quotation matches do not establish that a legal conclusion is correct.
What the review gives you
Check the evidence behind the answer.
The words behind the point
The source quotation and document line, so the lawyer can examine the record.
What still needs checking
Missing facts, unread material and unresolved points remain visible.

Questions
Before you try it.
What can I check in an answer?
Inspect the source quotation, document line, citation-check status and unanswered questions. Cortega combines drafting and review with these checks. The lawyer still assesses the facts, current law and conclusion before using the answer.
Which courts and rules are covered?
Civil deadlines cover federal, D.C., Maryland and Virginia cases. The rule-based tools identify the text they read and their gaps. Coverage varies by tool: selected Maryland discovery rules are included, while Maryland motion, expert and appeal packs have gaps. Each practice page lists the source status.
Can the practice use its own models?
Yes. Use private models inside the practice network, foundation models, the practice’s provider keys or a combination.
Does it decide what to argue or file?
No. Results are research aids. The lawyer checks the facts, authorities and conclusions and decides what to argue or file.
