Capabilities
What OpenCase does for corporate legal teams
Verified legal research
Ask a question and get an answer grounded in case law, statutes, and regulations — citations checked against primary law, and anything we cannot confirm is marked.
Contract and document review
Upload an agreement and identify key clauses, obligations, and risks, with each point traceable to the text it rests on.
Document comparison
Compare two versions of a contract to surface what changed and where terms deviate, so a redline does not slip past a manual read.
Drafting in Word and Google Docs
Draft agreements, memos, and policies directly in Microsoft Word and Google Docs, with the research and citations behind each point available as you write.
Matter organization
Group documents by matter and ask questions across the file, so the record for a deal or dispute stays in one place.
Jurisdiction-aware answers
Research is scoped to the jurisdiction you are working in, so the authority you cite is the authority that governs the question.
Outcomes
What verified research changes for a legal department
The mechanism behind every outcome is the same: answers you can trace to primary law.
Less time on manual research
Grounded answers with citations remove the read-and-reread pass, so counsel spend their time on judgment and negotiation instead of hunting for authority.
Citations you can defend
Verified cases and statutes link to the primary source, so you can confirm each one before it circulates.
Faster answers to the business
When a colleague needs a position on a clause or a regulation, a citation-backed answer is ready to send rather than queued behind a day of reading.
Consistent quality across the team
The same research rigor and the same verifiable sources apply whether the question comes from a senior lawyer or a first-year in-house hire.
Where it fits
How corporate lawyers use OpenCase
Reviewing commercial contracts
Upload a vendor or customer agreement, surface the clauses and obligations that matter, and check the governing law before you mark it up.
Answering questions from the business
Research the statute or regulation behind a product, marketing, or employment question and send back an answer with the authority attached.
Drafting agreements and policies
Write agreements, internal memos, and policies in Word or Google Docs with verified citations, then refine the language yourself before it goes out.
Comparing versions across a negotiation
Compare successive drafts of an agreement to catch what a counterparty changed and confirm nothing was quietly added or dropped.

- Cites cases or statutes that may be fabricated or no longer in force.
- Ignores which jurisdiction actually governs the question.
- A separate tool bolted on beside your document.

Common questions about AI for corporate lawyers
How does the legal research stay accurate?
Answers link back to the case law, statutes, or regulations they rest on. Verified citations link to the source, and ones we cannot confirm are marked. You can open each source and confirm it yourself, unlike generic tools that summarize without showing their work.
Can it review and compare contracts?
Yes. You can upload an agreement to identify key clauses, obligations, and risks, and compare two versions of a document to see exactly what changed between drafts.
Can it help me draft agreements and memos?
You can draft agreements, memos, and policies directly in Microsoft Word and Google Docs, with the research and verified citations behind each point available as you write.
Does it research the right jurisdiction for my question?
Research is scoped to the jurisdiction you are working in, so the case law, statutes, and regulations you cite are the authority that governs the question in front of you.
Is our company data kept confidential?
Your contracts and company data are encrypted in transit and at rest and are never used to train AI models or shared with other organizations. OpenCase maintains SOC 2 Type II compliance and ISO/IEC 27001 certification.
Does it work with the tools we already use?
OpenCase integrates with Microsoft Word, Outlook, Google Docs, Google Drive, Dropbox, and Clio, so you can research and draft alongside your existing workflow.
What if the AI gets something wrong?
OpenCase assists rather than replaces you. Because every finding carries a citation you can open, you can confirm the authority and apply your own professional judgment before relying on it.
