Irys or CoCounsel? It depends on where your firm already works.

It is strongest for organizations already invested in Thomson Reuters content and enterprise systems, where it can ground research and drafting in Westlaw and Practical Law under the customer's existing content subscriptions.

It is a broad product, not a research chatbot. Thomson Reuters publicly documents legal research, drafting, document analysis, legal workflows, linked citation endnotes, and tabular review of up to 10,000 documents against as many as 100 questions.

It also reaches deep into enterprise document systems. Public materials document connections to iManage in both cloud and on-premises deployments, HighQ, NetDocuments, SharePoint, Outlook, Word, and Microsoft Teams. Knowledge Search can span up to five configured sources in a single search.

Standard pricing is not publicly listed, and the buying process is sales-led. Public materials also indicate that some content and integrations require separate subscriptions: Westlaw and Practical Law results require the corresponding content entitlements.

Irys publishes its pricing. Irys One is $299 per month for one attorney. Irys Teams is $329 per seat per month for firms of 2 to 25 attorneys. There is no per-token or per-query overage on the advertised Irys One plan, and the 7-day trial requires no credit card.

Neither commercial model is inherently better. But when a price is not public, the burden shifts to you to ask what the quote includes, which content costs extra, and what happens at renewal.

Its enterprise integration surface is broader than ours. On-premises iManage, HighQ, and NetDocuments connections matter to large firms with entrenched document management systems, and CoCounsel covers them.

Tabular review at a scale of 10,000 documents and 100 questions is a genuine capability for large diligence and review projects.

Thomson Reuters is also an established vendor relationship for many firms, which can simplify procurement, security review, and support.

Its core product does not require a preexisting research content relationship. You sign up, start the trial, and evaluate it on a real matter the same day, without a sales call.

Irys is built around the matter, not the query. Research, drafting, and document analysis share persistent matter context, so the next task can use the facts, documents, and authorities already in the matter instead of forcing you to rebuild the context in a new prompt.

Output is source-linked. Material statements link to the supporting source so you can verify the work rather than take it on faith.

Irys works where the work happens. Irys works where the work happens. A Word add-in brings drafting into your documents, and Workbench, currently in beta, can take connected actions across applications such as email and cloud storage. Workbench requires your approval and does not send communications autonomously.

Finished work product is part of the platform, including built-in e-signature, so a matter can move from research to a signed document without switching tools.

Take one live matter, run it through both products, and ask the same questions of each.

Not publicly listed means we found no standard public price; actual pricing and contract terms may vary.

Features on either side may require particular plans, content subscriptions, or integrations, and both products change quickly. If anything here is out of date, tell us and we will correct it.
