Capabilities

What legal AI actually delivers.

Massive Time Savings

5–10x faster document creation. What takes 8 hours today takes 1 hour with AI. That's real billable time recovered every single day.

Exceptional ROI

300–500% ROI in the first year, with payback periods as short as 2–3 months. Average savings exceed $150,000 annually per attorney.

Improved Accuracy

90% reduction in document errors. AI-powered consistency means less rework, fewer malpractice risks, and higher-quality output.

3x Client Capacity

Handle three times as many clients with the same staff. AI doesn't replace attorneys — it removes the bottlenecks that limit how many you can serve.

Enhanced Client Satisfaction

Faster turnaround, higher quality work, and 24/7 availability. Clients notice the difference and stay longer.

Competitive Advantage

Firms using AI are winning clients from those who aren't. The competitive gap between AI-adopters and holdouts widens every quarter.

The honest breakdown

Is legal AI worth it? Here's the math.

A solo attorney billing $300/hour who saves just 10 hours per week generates $156,000 in additional billable capacity annually. Carta AI costs $49–299/month. The math isn't complicated — the only question is whether you'll act on it.

Document drafting: 8 hours → 1 hour

Complex contract drafts that take a full day now take under an hour. That's 7 hours recovered per document.

Legal research: hours → minutes

AI-powered natural language search surfaces relevant case law in minutes. Traditional research often takes half a day.

Contract review: same day turnaround

AI extracts key clauses, flags risks, and summarizes positions instantly. Clients get answers the same day instead of waiting a week.

No outsourcing costs

Tasks previously sent to contract attorneys or legal process outsourcing firms can be handled in-house with AI assistance.

“OpusLaw paid for itself in 6 weeks. We're now handling 3x more cases with the same staff, and client satisfaction has never been higher. Every law firm should be using this.”
