Capabilities
What OpenCase does for attorneys
Verified legal research
Ask a question and get an answer grounded in case law, statutes, regulations, and court rules — each point linked to the primary source behind it.
Drafting in Word and Google Docs
Draft and revise memos, briefs, and correspondence directly in Microsoft Word and Google Docs, with legal grounding instead of generic phrasing.
File upload and analysis
Upload contracts, filings, and case documents and ask questions about them. OpenCase reads the file and answers with references to the text.
File comparison
Compare documents side by side to surface differences, missing terms, and inconsistencies across versions and agreements.
Matter organization
Keep documents and research grouped by matter, so the context for each case stays together and easy to return to.
Calendar and time tracking
Track deadlines and record time alongside your research and drafting, keeping the administrative side of a matter in one place.
Outcomes
What citation-backed AI changes
The mechanism behind every outcome is the same: answers you can trace to primary law.
Research you can cite with confidence
Because every answer links to its source, you validate a point by opening the citation rather than re-running the search by hand.
Less time on the mechanical work
Drafting, file review, and document comparison move faster, so attorney time goes to judgment and strategy instead of scanning.
Fewer missed details
Consistent analysis across statutes, rules, and uploaded files catches obligations and risks that review fatigue tends to let slip.
One place for a matter
Research, drafts, files, deadlines, and time entries stay organized by matter, so the full context is where you need it.

Common questions about AI for attorneys
How is this different from general AI tools like ChatGPT?
OpenCase answers legal questions with citations to primary law — case law, statutes, regulations, and court rules — and verifies those citations against the source. General tools often produce unreliable or fabricated citations, and they have no place for drafting in Word, analyzing your files, or organizing matters.
What sources does the legal research draw on?
Research is grounded in primary legal sources including case law, statutes, regulations, and court rules. Each answer links back to the source it relies on, so you can open it and confirm the point before relying on it.
Can I draft documents in Word and Google Docs?
Yes. OpenCase works inside Microsoft Word and Google Docs so you can draft and revise memos, briefs, and correspondence where you already work. It also integrates with Outlook, Google Drive, Dropbox, and Clio.
Can I upload and analyze my own documents?
Yes. Upload contracts, filings, and case documents and ask questions about them, and OpenCase answers with references to the text. You can also compare documents side by side to surface differences and missing terms.
What happens to my client data and case information?
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 access controls over sensitive legal data.
Does OpenCase replace my judgment?
No. OpenCase assists rather than replaces you. Because every answer carries a verifiable citation, you can confirm the research and apply your own judgment before relying on it in a filing or advising a client.
What does it cost to get started?
OpenCase has a free tier, so you can create an account and run your first research query without a credit card. See the pricing page for plan details as your usage grows.
