Everlaw is the best AI tool for litigation in 2026. It dominates e-discovery with predictive coding that actually works, and its AI-powered review tools cut document review time by 50-70%. For litigation teams, document review is where AI saves the most money — and Everlaw does it better than anyone.

Litigation AI has matured past the hype phase. The tools on this list aren't experimental — they're running in AmLaw 100 firms and winning cases. The question isn't whether to use AI in litigation, it's which tools to deploy at which stage. Here's the litigation AI toolkit, matched to the phase of your case.

Everlaw — Best for E-Discovery and Document Review

Everlaw's AI-powered document review platform uses predictive coding, clustering, and natural language search to help litigation teams find relevant documents in massive productions. The AI learns from your coding decisions and prioritizes the most relevant documents first — cutting review time by 50-70% on average. The platform also handles production, privilege logs, and trial preparation. Pricing is volume-based (typically $25-$75 per GB/month). Best for any firm handling document-intensive litigation. The limitation: it requires a learning curve, and smaller matters may not justify the platform overhead.

DISCO — Best End-to-End Litigation Platform

DISCO's Cecilia AI agent goes beyond traditional e-discovery — it handles document review, legal research, and case analysis in a single platform. The agentic AI approach means you can ask complex questions like "find all documents where the CFO discussed the merger timeline" and get relevant results ranked by confidence. DISCO also handles data processing, review, and production. Pricing is competitive with Everlaw on a per-GB basis. Best for firms that want one platform for the entire litigation workflow. The limitation: the agentic AI features are newer and still proving themselves on complex edge cases.

Clearbrief — Best for Brief Writing and Cite Checking

Clearbrief is a Word add-in that verifies every factual claim in your brief against the cited source. Upload your exhibits and record, draft your brief, and Clearbrief flags unsupported statements, incorrect citations, and missing exhibits in real time. It also generates tables of authorities and checks for Bluebook compliance. Pricing starts around $150/month. Best for litigation teams that file regularly and can't afford citation errors. The limitation: it's a quality-control tool, not a drafting tool — it catches mistakes but won't write your brief for you.

Harvey is the $11B AI company that's captured BigLaw. It handles legal research, memo drafting, contract analysis, and case strategy — trained specifically on legal data. Over 100,000 lawyers use it across firms like Allen & Overy and PwC. For litigation, it excels at researching novel legal questions, drafting research memos, and analyzing opposing counsel's arguments. Pricing is enterprise-only. Best for AmLaw firms that need a general-purpose legal AI with strong research capabilities. The limitation: enterprise-only pricing puts it out of reach for smaller firms.

Darrow — Best for Case Finding and Evaluation

Darrow uses AI to identify potential litigation opportunities by scanning public data for patterns of harm — consumer fraud, data breaches, employment violations, product defects. It also evaluates case viability and estimates potential damages. For plaintiff-side litigation firms, it's a case-generation engine. Pricing is typically success-based or subscription. Best for plaintiff firms looking to identify class actions and mass torts before competitors. The limitation: it's a plaintiff-side tool — defense firms won't find much use for it.

Building Your Litigation AI Stack

The core litigation stack is Everlaw or DISCO for e-discovery (pick based on your volume and budget), Clearbrief for brief quality control, and Harvey for research and drafting if your firm has the budget. Add Darrow if you're on the plaintiff side. Don't try to adopt everything at once — start with e-discovery AI (the biggest time savings) and add tools as your team gets comfortable.

The Bottom Line: Everlaw is the single best investment for litigation teams — AI-powered document review delivers the largest, most measurable time savings in the entire litigation workflow.
