GC AI includes a dedicated US case law database directly in chat. Ask a case law question in plain language and get a cited, synthesized answer grounded in the actual opinions. Every cited case links to the full text through a built-in Opinion Reader.

​
How it works

  1. Ask your question. Type a case law question in chat. GC AI automatically searches relevant opinions when your question calls for it.
  2. GC AI searches and reads. GC AI searches the database, reads full opinions, checks treatment status where available, and synthesizes an answer with citations.
  3. Verify your sources. Click any hyperlinked case name or use the View Opinion button in the citation hover card to open the full opinion in the sidebar. Search within it or download it.
You’ll see a “Searched case law” indicator in the chat when GC AI uses the case law database. Expand it to see which cases were retrieved.

​
Source controls

US Case Law is on by default. GC AI searches case law whenever your question calls for it, without any setup required. You can adjust your sources from the Add menu:
  • US Case Law toggle: Turn off if you don’t regularly need case law in your conversations. This setting persists across chats.
  • Web toggle: Turn off for case law only results. This setting applies within a single conversation.
  • Advanced Settings: Open the jurisdiction picker to filter by court level and state. This setting applies within a single conversation.
Specifying jurisdiction directly in your query (e.g., “under Delaware law”) is often faster than using the jurisdiction picker.

​
What’s in the database

The case law database includes 13M+ US opinions covering:
  • Federal courts at every level (Supreme Court, Circuit Courts, District Courts)
  • State supreme and appellate courts across all 50 states and D.C., plus the Court of Chancery for Delaware
  • Select specialized courts (e.g., Tax Court)
Opinions are sourced from authoritative publishers like court websites and government records through Midpage AI. The database is actively maintained and regularly updated.

​
Opinion Reader

Click a hyperlinked case name in any response to open the full opinion in the sidebar, or hover or click a citation and click View Opinion. From the Opinion Reader you can:
  • Read the complete opinion text
  • Search within the opinion for specific terms
  • Download the opinion
The Opinion Reader opens alongside your chat, so you can verify sources without losing your place in the conversation.

​
Citations and treatment

Every case GC AI cites links to the full opinion. Citations appear as hyperlinked case names in the response. When treatment information is available, GC AI displays treatment flags alongside citations:
  • Negative: The case has been reversed, overruled, or otherwise negatively treated
  • Cautionary: The case has been distinguished, questioned, or criticized
  • Positive: The case has been followed or affirmed
  • Neutral: Notable subsequent history without a clear positive or negative signal
Treatment flags are not available for every case. For recent decisions or cases with limited subsequent history, treatment may not appear. Always verify critical citations independently.

​
Case law summary tables

For multi-case research questions, GC AI may produce a structured summary table breaking down each case by:
  • Citation
  • Facts
  • Issue
  • Holding
  • Application to your question
Summary tables are especially useful for jurisdiction surveys, comparing how different courts handle the same issue.

​
Combining case law with other work

Case law works alongside everything else in GC AI. In a single conversation you can:
  • Upload a contract, flag risks, then research the case law on specific issues
  • Ask a case law question, then draft a memo incorporating the findings
  • Combine web research and case law for a comprehensive answer
  • Use case law to support a position in a negotiation
Case law is also available in chats within a Project and in chats run as part of Automations.

​
Example prompts

  • Contract clause enforceability (sample chat): “We’re negotiating a SaaS agreement governed by Delaware law. Can we enforce the forum selection clause in our customer terms of service?”
  • Multi-jurisdiction survey (sample chat): “Do New York, Illinois, and Texas courts recognize the inevitable disclosure doctrine for trade secrets? Compare their approaches.”
  • Evolving precedent tracking (sample chat): “How are courts in the Second Circuit applying Muldrow v. City of St. Louis to Title VII retaliation claims? Is ‘some harm’ now the standard, or does the Burlington Northern ‘materially adverse’ test still apply to retaliation?”
  • Case lookup and plain-language summary (sample chat): “Pull up E.M.D. Sales, Inc. v. Carrera, 604 U.S. 45. Summarize the holding and draft an email from me containing 3-4 plain-language takeaways I can share with my leadership team.”

​
Availability

US Case Law is included in all Team and Enterprise plans. For Individual seats, it is available as an add-on.

​
Data and security

Case law data is provided by Midpage AI, a subprocessor that provides the legal research database and search infrastructure. Midpage is SOC 2 Type II compliant. Their role is limited to providing legal research content and search infrastructure. GC AI does not maintain a case law corpus. Opinions are fetched live from Midpage’s API when you search or open the Opinion Reader. Citation snippets and metadata are stored as part of your chat history for display purposes only.

​
Common questions

​
Is this available outside the US?

US case law is available now. Additional jurisdictions, namely EU and UK case law, will launch next. Traditional legal research platforms give you a search interface to run boolean queries and read results. GC AI is AI-native: you describe what you need in plain language, and GC AI searches, reads, and synthesizes opinions into a cited answer. Your time goes to evaluating the analysis. For exhaustive litigation research, like building a complete state trial court research trail, reviewing academic treatises, or pulling full administrative tribunal dockets, some teams keep a traditional research platform seat alongside GC AI. These products add a generative AI layer on top of databases originally built for manual, keyword-driven research. The AI and the database are tightly coupled, and the fit between the two can affect the quality of results, especially when the underlying architecture wasn’t designed for AI-driven retrieval. GC AI’s case law capabilities were built around AI from the start. Case law is fetched live from a dedicated legal database and read alongside your contracts, playbooks, and company context, so the output is grounded in the work in front of you. Each cited case links to the full opinion. Some general-purpose AI platforms offer legal plugins that connect to third-party research databases and other legal tools. The research experience depends on which connectors you’ve set up and which subscriptions you hold. GC AI is built for in-house counsel. US Case Law is built directly into the same workspace your team already uses for contracts, drafting, web research, playbooks, and company context, with control and verification designed into the experience. There are no modes to switch between and nothing to install.

​
Is US Case Law available in shared chats?

Case law citations are visible in shared chats. Authenticated org members with US Case Law access can click through to read the full opinion. Readers viewing a shared chat via a public link can see the citations but cannot open the full opinion.

​
How current is the data?

Midpage AI’s database is actively maintained and regularly updated. There may be a short lag before newly published opinions appear in GC AI, as Midpage processes the data before it becomes searchable.
