Irys vs CoCounsel
An AI add-on to your existing Westlaw subscription — or a standalone platform that does not require one?
CoCounsel is Thomson Reuters' AI assistant, now integrated into the Westlaw platform. It brings conversational AI to legal research — but it requires a Westlaw subscription, is limited primarily to research tasks, and is priced as an upsell on an already-expensive stack.
What CoCounsel does well
CoCounsel brought structured AI-assisted legal research to the Thomson Reuters ecosystem early. Skills like document review, legal research memos, contract analysis, and timeline creation offer real utility for attorneys already working inside Westlaw.
The integration with Westlaw's content library means CoCounsel responses are grounded in one of the most comprehensive case law databases available. For firms that have already invested heavily in Thomson Reuters infrastructure, CoCounsel adds AI capability without requiring a new vendor relationship.
Where the limitations show
CoCounsel is not a standalone product. It requires an active Westlaw subscription, which means the cost of AI is layered on top of an already significant annual spend — often $50K–$300K+ before CoCounsel pricing is added. For small and mid-size firms, the total cost of entry can be prohibitive.
The scope of CoCounsel is primarily research-oriented. There is no native drafting assistant, no matter management, no document comparison workspace, and no persistent workflow layer that carries context from one task to the next. Each interaction is largely self-contained.
For teams evaluating legal AI as a way to transform how they work — not just how they search — CoCounsel's dependency on the Westlaw ecosystem and its research-first scope can feel constraining.
How Irys approaches it differently
Irys is a standalone platform. There is no prerequisite subscription, no legacy system dependency, and no enterprise sales cycle required to get started. A team can sign up, start a 14-day free trial, and evaluate the product on real work.
More fundamentally, Irys is not an AI add-on to a research tool. It is a unified environment where research, drafting, document intelligence, and matter context are connected by design. Research informs drafting. Matter context persists. Work product compounds across sessions instead of resetting with every new query.
The pricing model reflects this difference: $299/month per seat, transparent and self-serve. No bundled upsells, no opaque enterprise contracts, no requirement to buy a separate platform just to access the AI.
The real choice
CoCounsel makes Westlaw smarter. That is genuine value for firms already committed to the Thomson Reuters stack. But for teams asking whether they need a smarter research tool or an entirely new kind of legal work platform, the answer may point somewhere else.
Irys is built on the thesis that legal AI should not be an add-on to an existing product — it should be the product. A platform where every capability is designed to work together, context carries forward, and the total cost of ownership is clear from day one.
This comparison is based on publicly available information and Irys's current product positioning as of March 2026. CoCounsel's offerings may evolve, and product fit will vary by workflow, practice area, deployment requirements, and team size.
