Legal · Custom AI DevelopmentCustom AI development for law firms & legal teams
Generic legal tech ends at intake. Your firm’s real bottlenecks run deeper. Custom AI development goes where the templates can’t.
Intake widgets, billing tools, and document templates each cover one task. A firm’s workflow spans intake, conflict checks, matter management, document review, and billing — across your practice management system, all at once.
Nexum builds custom AI systems for law firms — intake-to-matter pipelines, document processing, and billing workflows wired into Clio, MyCase, and PracticePanther. Administrative and operational work only, with attorney oversight built in. Delivered in 6-8 weeks at a fixed price from $12,500.
Every build is scoped to your firm during a free diagnosis. These are the custom AI systems law firms most often ask us to build — all operational, none replacing legal judgment.
01
Intake-to-matter pipeline
Captures potential-client inquiries across channels, qualifies by practice area, runs structured conflict-check prompts, drafts engagement paperwork for attorney review, and opens the matter in your practice management system — so no qualified lead waits and no conflict slips through.

Practice-area qualification
Structured conflict-check prompts
Engagement draft for attorney review

HOW WE BUILD IT
From audit to production in 6-8 weeks
Fixed price confirmed before any build begins. Your team keeps operating normally throughout.
Weeks 1-2
Audit & architecture
We map your operation, the systems involved, and the exact workflows to automate, then design the system architecture and confirm a fixed price before any build begins.
Weeks 3-6
Build & integration
We build the AI logic and integrate it with your existing tools and data sources. Your team keeps operating normally throughout — no disruption.
Weeks 6-7
Testing & onboarding
We test every scenario against real data and walk your team through what the AI handles and what escalates to them. No technical training required.
Weeks 7-8+
Go-live & maintenance
The system goes live with documentation, a handover walkthrough, and a 30-day support window. Ongoing partnership keeps it optimized as you grow.
Every legal build is administrative and operational only. The AI never provides legal advice, never makes legal judgments, and is designed to preserve client confidentiality and attorney oversight at every step.
