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.

WHAT WE BUILD

Custom AI systems for legal

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.

What it delivers

  • Multi-channel intake capture
  • Practice-area qualification
  • Structured conflict-check prompts
  • Engagement draft for attorney review
  • Matter creation in PM system

  • Clio
  • MyCase
  • PracticePanther
  • Lawmatics

02

Document processing & review support

Reads and extracts from contracts, discovery sets, and filings; classifies and summarizes; flags key clauses, dates, and obligations; and routes to the right attorney. The AI does the grunt work — the attorney reviews and decides.

What it delivers

  • Contract & filing extraction
  • Classification & summarization
  • Clause, date & obligation flagging
  • Routing to the right attorney
  • Searchable document index

Built on / integrates

  • Clio
  • NetDocuments
  • iManage

03

Billing, time-capture & expense automation

Captures billable activity across systems, reconciles expenses, drafts invoices for review, and runs accounts-receivable follow-up — recovering billable hours that currently leak through manual time entry.

What it delivers

  • Billable activity capture
  • Expense reconciliation
  • Invoice drafting for review
  • AR follow-up sequences
  • Realization & leakage reporting

Built on / integrates

  • Clio
  • QuickBooks
  • Stripe
  • LawPay

04

Client communication & status automation

Runs onboarding, matter status updates, deadline and appointment reminders, and post-matter review requests — escalating to staff whenever something needs a human. Clients stay informed without adding to anyone’s plate.

What it delivers

  • Client onboarding sequences
  • Matter status updates
  • Deadline & appointment reminders
  • Review & referral requests
  • Escalation to staff

Built on / integrates

  • Clio
  • MyCase
