The Unique Pressures of Criminal Defense Work
Defense attorneys manage caseloads that would overwhelm most professionals. Public defenders and private criminal defense firms alike face systemic challenges that technology can help address — without compromising the zealous representation every client deserves.
- Speedy trial deadlines that vary by jurisdiction and charge severity
- Massive discovery dumps — body camera footage, phone records, financial documents — that must be reviewed under tight timelines
- Motion practice that requires deep statutory and case law research
- Communicating with incarcerated clients who have limited phone access
- Managing bail hearings, plea negotiations, and trial prep simultaneously across dozens of cases
How Lexi AI Helps Criminal Defense Attorneys
Rapid Discovery Review and Organization
Prosecutors often produce thousands of pages of discovery. Lexi ingests discovery materials and creates organized summaries — identifying key witnesses, inconsistent statements, and exculpatory evidence that might otherwise get buried. Ask Lexi to find every mention of a specific witness or pull all references to a particular date, and it returns results in seconds rather than hours.
Motion Drafting and Legal Research
From motions to suppress to motions to dismiss, Lexi's legal research engine pulls relevant case law from Westlaw and Fastcase, identifies the strongest authorities for your argument, and drafts motion frameworks based on your jurisdiction's requirements. Attorneys refine the work product rather than building from scratch — a critical time-saver when you have a suppression hearing in 72 hours.
Client Intake for Defense Practices
When a family member calls at 2 AM because someone was just arrested, Lexi's automated intake captures the charges, jurisdiction, bond status, and next court date — then alerts the on-call attorney immediately. No missed calls, no lost clients. The intake data syncs directly to your case management system so the file is partially built before the attorney even picks up the phone.
Speedy Trial and Filing Deadline Tracking
In criminal defense, missing a deadline can mean your client loses a constitutional right. Lexi tracks speedy trial calculations, motion filing windows, discovery response deadlines, and appeal timelines. It factors in tolling events and continuances, sending proactive alerts in your Slack channels so your team always stays ahead of the calendar.
