Capabilities
How the platform improves legal research
Verified citations linked to primary sources
Verified cases, statutes, and regulations link to the original document, and anything we cannot confirm is marked, so you know what to check before it reaches a brief or memo.
Coverage of case law, statutes, and regulations
Research spans federal and state jurisdictions across case law, statutory codes, administrative regulations, and court rules, so you get a complete picture in one place.
Intuitive search and filtering
Narrow results by jurisdiction, date, court level, and topic. Filters remove irrelevant material so you locate the right precedent or statute in minutes.
Grounded answers you can trace
Answers are anchored to verified legal authority rather than generic text, and each supporting source is one click away for you to confirm.
Outcomes
What verified legal research changes
The mechanism behind every outcome is the same: sources you can trace to primary law.
Less time on manual verification
Automated citation checks remove the cross-referencing pass, so time that went to validating sources goes to analysis and case strategy instead.
Citation errors caught early
Outdated or incorrect references are flagged before they reach a filing, so your work reflects the precision judges and opposing counsel expect.
Confidence in every source you cite
Knowing each citation links to a verified primary source removes doubt from your research and lets you argue from authoritative, current authority.
Compliance research stays current
Statutes and regulations change often. Grounding in primary law keeps regulatory research aligned with the versions that apply today.

Common questions about our legal research software
How does citation verification work?
Each citation is checked against primary law as you research. Verified citations link directly to the primary source document — a case, statute, or regulation — and ones we cannot confirm are marked, so you know what to check before filing.
What jurisdictions and sources are covered?
The platform covers federal and state case law, statutory codes, administrative regulations, and court rules. Research draws on primary legal authority so your work reflects current, comprehensive coverage for litigation, compliance, and academic use.
Can I export citations to my existing documents?
Yes. Integrations with Microsoft Word, Outlook, Google Docs, Google Drive, Dropbox, and Clio let you bring verified citations and research into the tools you already use, so your workflow stays uninterrupted from research to final document.
How is this different from other legal research tools?
The platform links results directly to verified primary sources rather than summarizing without showing its work. Automated verification and grounding in primary law mean less time on manual checking and more time on high-value analysis.
Is my research data secure and confidential?
Your data is encrypted in transit and at rest and is never used to train AI models or shared with other organizations. OpenCase maintains SOC 2 Type II compliance and ISO/IEC 27001 certification, with AI governance aligned with ISO 42001.
What if a source needs my own judgment?
The platform assists rather than replaces you. Because verified results link to primary law, you can open the source, confirm the analysis, and apply your own judgment before relying on it.
