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

Thomson Reuters does not publish a standard seat price for CoCounsel. 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 50 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.

If your organization holds Westlaw and Practical Law subscriptions, CoCounsel grounds AI output in one of the most authoritative legal content ecosystems available, with citation support delivered through a research environment your attorneys already trust.

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.

Irys is a standalone platform. 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.

Do not decide on marketing pages, including this one. Take one live matter, run it through both products, and ask the same questions of each.

Can it locate the exact source behind a factual statement in its output?

Can it confirm whether a cited authority is still good law, and what content subscription that check requires?

Can it carry context from research into a later drafting or review task without rebuilding the matter?

Can it work across email, files, research, and Word without manual copying?

Can it produce a usable file rather than only chat text?

What happens when the matter contains hundreds or thousands of documents?

What is excluded from the quoted price, and which features require separate content subscriptions?

Are there document, query, storage, or integration charges beyond the seat price?

What happens to the price at renewal, and can you run a real matter before signing a long-term agreement?

This page is based on publicly available information from Thomson Reuters and Irys materials, reviewed August 3, 2026. 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.
