Irys vs Westlaw
Legacy research platform — or a unified environment for modern legal work?
Westlaw is the incumbent. Three decades of case law, trusted citator tools, and deep adoption across BigLaw. But the AI layer is bolted onto legacy infrastructure, pricing is punitive ($50K–$300K+/year for most firms), and there is no self-serve path to get started.
What Westlaw does well
Westlaw has one of the most comprehensive case law databases in the world. KeyCite is the gold standard for citation verification. The editorial enhancements — headnotes, key numbers, annotations — reflect decades of human curation that no AI-first platform can replicate overnight.
For firms deeply embedded in the Thomson Reuters ecosystem, Westlaw is familiar. Training is minimal because most associates learned it in law school. That institutional muscle memory is real and should not be dismissed.
Where the gap starts
Westlaw's AI capabilities — including CoCounsel integration — are additions to a platform architected before AI existed. The experience is research-first, not workflow-first. You can ask questions and get answers, but there is no native drafting environment, no matter management, no document comparison, and no collaboration layer that ties research output to the rest of the legal workflow.
Pricing remains a significant barrier. Enterprise contracts typically run $50K–$300K+ per year depending on firm size and modules selected. There is no self-serve option, no transparent per-seat pricing, and no trial that lets a team evaluate the product on real work before committing budget.
For teams that want AI to change how they work — not just how they search — the gap between Westlaw's capabilities and what a modern legal workflow demands is growing wider.
How Irys approaches it differently
Irys is purpose-built around the thesis that AI should not be an add-on to a research database. It should be the environment where legal work happens: drafting, research, document intelligence, and matter context living in one connected system.
That means research results flow directly into drafting. Matter context persists across sessions. Document comparison happens natively. And the platform learns from how your team works — building operational leverage over time instead of resetting with every new query.
Pricing is transparent: $299/month per seat with a 14-day free trial. No enterprise sales cycle required to evaluate the product. No six-figure annual commitment before your team has seen whether it fits their workflow.
The real choice
Westlaw is not going away. For pure legal research with editorial depth, it remains a serious tool. The question is whether research alone is enough — or whether your team needs a platform where research, drafting, analysis, and matter context are unified by design.
Irys is built for the second bet: that the future of legal work is not a better search engine with AI on top, but a new kind of platform where AI is the foundation and every capability compounds on the one before it.
This comparison is based on publicly available information and Irys's current product positioning as of March 2026. Westlaw's offerings may evolve, and product fit will vary by workflow, practice area, deployment requirements, and team size.
