Capabilities

Everything Westlaw offers — and more.

Natural Language Search

Ask legal questions in plain English. Carta AI understands context and intent, surfacing relevant case law faster than Westlaw's Boolean keyword system.

Comprehensive Case Law

Full US federal and state coverage plus 25+ international jurisdictions — the same depth you expect from Westlaw, at a fraction of the cost.

AI-Generated Summaries

Instant case summaries and key-point extraction included at no extra charge. No add-on subscription required unlike Westlaw Precision.

Contract Analysis

Review and annotate contracts in minutes. A capability Westlaw simply doesn't offer — included in every Carta AI plan.

Document Drafting

Draft briefs, memos, and motions with AI assistance. Carta AI is a full practice platform, not a research-only tool.

Practice Hub — 15+ Tools

Citation checker, deadline calculator, brief builder, and more. Everything you need to practice at your best, all in one place.

Why attorneys switch

Westlaw is expensive. Carta AI is everything else.

Westlaw built its moat on data — but AI has changed what's possible. Carta AI delivers the same research depth with conversational search, AI summaries, contract analysis, and document drafting. Most attorneys recoup the subscription in the first research session.

No per-query pricing

Westlaw charges per search or per document viewed. Carta AI is a flat monthly subscription — research as much as you need.

Instant setup

Westlaw onboarding takes days to weeks. Carta AI is live in under two minutes, no training required.

Solo and small firm pricing

Westlaw pricing is designed for large firms. Carta AI starts at $49/month — built for every attorney, not just BigLaw.

50+ language support

Research and draft in 50+ languages. Westlaw is English-primary, making Carta AI the clear choice for international matters.

We were spending $400/month on Westlaw and still felt like we were fighting the interface. Carta AI costs less, answers faster, and actually helps me draft. It wasn't a close call.
