Iqidis vs CoCounsel: A 2026 Comparison

Iqidis vs CoCounsel is a choice between a self-serve legal AI platform and one grounded in Thomson Reuters content. Iqidis, now Irys, organizes research, drafting, and document analysis around the matter. CoCounsel Legal reasons from Westlaw and Practical Law content to handle research, analysis, and drafting.

Key takeaways

• Iqidis vs CoCounsel turns on where the legal authority comes from. Irys runs research against the Irys case-law database with a built-in citation check. CoCounsel Legal reasons from Westlaw and Practical Law.
• Iqidis is now Irys. Iqidis, Inc. rebranded to Irys in March 2026, and the main product is now called Irys One. The legal entity, team, and security certifications are unchanged.
• Irys publishes pricing and CoCounsel does not. Irys One costs $299 per month for one seat with a 7-day trial. CoCounsel is priced through the Thomson Reuters configurator or a sales conversation, with no self-serve trial.
• Both work inside Microsoft Word. Irys applies AI edits as tracked changes, and CoCounsel for Microsoft Word supports clause review and playbook-based review.
• The security certifications differ. Irys lists SOC 2 Type II, ISO 27001, and HIPAA compliance. CoCounsel Legal lists SOC 2 and ISO 42001.

What is Iqidis (now Irys)?

Iqidis, now called Irys, is a legal AI platform for practicing attorneys and legal teams, sold by Iqidis, Inc. The company rebranded from Iqidis to Irys in March 2026, renamed the product from Iqidis to Irys One, and moved the website to irys.ai. The Irys rebrand notice states that existing contracts, subscriptions, security certifications, and the team are unchanged, so buyers researching Iqidis are evaluating the same product.

Irys organizes work around the matter. Irys describes a Matter as "the unit of work in Irys One," a shared container for the documents, conversations, drafts, tasks, and AI context of a single case, deal, or project. Practice tools such as the Drafting Assistant, Compare, and Multi-Doc Analysis open with that matter context already loaded.

Research is built into the same workspace. The Irys case-law search covers all US federal courts and the appellate and supreme courts of every state, with semantic and boolean search. A Cite Check feature flags hallucinated cases, cases with treatment signals indicating they have been overruled, and parallel citation mismatches. For drafting, the Irys Drafting Assistant renders every AI change as a tracked change, and the Irys Word add-in brings the same engine into Microsoft Word at no extra cost on every plan.

Pros

• Published pricing from $299 per month, with a 7-day trial that needs no credit card
• Research, drafting, and document analysis in one matter-based workspace
• Cite Check for hallucinated, overruled, and mismatched citations
• Every AI edit shown as a tracked change, in the Drafting Assistant and in Word
• SOC 2 Type II, ISO 27001, and HIPAA compliance, with zero-retention model inference

Cons

• The documented case-law coverage is US federal and state courts, so teams working primarily in other jurisdictions need another research source
• The Word add-in's Document Editor currently supports Accept All and Reject All for tracked changes, rather than change-by-change control inside the editor
• The Irys Lite plan at $19.99 per month carries daily usage caps, so a full evaluation runs on Irys One or the Irys One trial

Pricing: Irys One costs $299 per month for one seat, or $3,049 per year on annual billing. Irys Teams costs $329 per seat per month for 2 to 25 seats, and Irys Enterprise is priced to scope above 25 seats. Irys pricing also lists a capped Irys Lite plan at $19.99 per month.

What is CoCounsel?

CoCounsel is the legal AI product from Thomson Reuters, sold in tiers. CoCounsel Essentials is the AI assistant on its own, and CoCounsel Legal is the full product, which draws on Westlaw primary law and Practical Law guidance alongside an organization's own documents.

Thomson Reuters describes CoCounsel Legal as reasoning from "authoritative Westlaw content, trusted Practical Law guidance, and your organization's own knowledge." A user describes a task in plain language, and CoCounsel Legal builds a step-by-step plan with reasoning that can be inspected. The product includes Deep Research, Westlaw Brief Builder for litigation briefs, and document analysis that Thomson Reuters says can review "up to 10,000 documents against 100 questions," with every answer traceable to its source.

According to Thomson Reuters' May 2026 announcement, "the next generation of CoCounsel Legal is rebuilt on Anthropic's Claude Agent SDK." CoCounsel for Microsoft Word brings contract review, drafting, and playbook-based review into Word, and CoCounsel Legal connects to document management systems including iManage and NetDocuments.

Pros

• Research grounded in Westlaw primary law and Practical Law guidance on the CoCounsel Legal tier
• Step-by-step plans with inspectable reasoning for multistep legal work
• Document analysis across up to 10,000 documents, with answers traced to source
• CoCounsel for Microsoft Word for clause review and playbook-based review
• Integrations with iManage and NetDocuments, plus SOC 2 and ISO 42001 certification

Cons

• No self-serve trial, so evaluation runs through Thomson Reuters sales
• The Westlaw and Practical Law grounding that defines CoCounsel Legal sits in the higher-priced tier, not in Essentials
• Pricing depends on firm size, jurisdiction, and term, so the cost is only known after configuration

Pricing: the Thomson Reuters configurator lists CoCounsel Essentials at about $1,464 per month, roughly $293 per user, for a five-attorney firm on a one-year term with all-states and federal coverage. On the same settings, CoCounsel Legal costs about $2,461.60 per month, roughly $492 per user.

What are the main differences between Iqidis and CoCounsel?

The main differences between Iqidis and CoCounsel are where the legal authority comes from, how the work is organized, how each works in Word, and how each is secured and bought.

Where the legal authority comes from

Irys runs AI legal research against the Irys US case-law database and checks citations with Cite Check. CoCounsel Legal reasons from Westlaw and Practical Law, the Thomson Reuters editorial content that firms license separately. For a firm that already pays for Westlaw, CoCounsel Legal extends a research source the lawyers trust. For a firm without that subscription, Irys provides case-law research without requiring a separate research subscription.

How the work is organized

Irys puts the matter at the center: documents, conversations, drafts, and tasks for one case or deal sit in one container, and every tool opens with that context. CoCounsel Legal puts the request at the center: a lawyer describes the task, and CoCounsel Legal plans and works through the steps. A team that wants a shared workspace per matter is closer to the Irys design. A team that wants to hand off a multistep research or analysis task is closer to the CoCounsel Legal design.

Working in Microsoft Word

Both vendors offer a Word add-in. Irys shows every AI edit as a tracked change, and the Irys add-in is included on every Irys plan. CoCounsel for Microsoft Word lets a reviewer select a clause, see a summary of any issue with suggested revisions, and insert those revisions into the document, alongside playbook-based review.

Security and data handling

Irys lists SOC 2 Type II attestation, ISO 27001 certification, and HIPAA compliance, and states that model inference runs with zero retention and that customer content is not used to train models. CoCounsel Legal lists SOC 2 and ISO 42001 certification, the international standard for AI management systems, and Thomson Reuters states that customer data is never used to train underlying models.

A team with specific requirements should ask each vendor which SOC 2 report type applies to the product being purchased, and whether and how data residency outside the US is supported.

How much do Iqidis and CoCounsel cost?

The Iqidis vs CoCounsel cost comparison starts with how each is sold: Irys publishes plan pricing, and CoCounsel is priced by configuration.

Irys figures come from the Irys pricing page. CoCounsel figures come from the Thomson Reuters configurator for a five-attorney firm on a one-year term with all-states and federal coverage. Confirm current pricing with each vendor before deciding.

What the pricing models mean for an evaluation

Irys can be evaluated the same day on the 7-day trial, and the Irys pricing page states that "the rate you sign is the rate at renewal." CoCounsel requires a configuration or a sales conversation first, so a firm should plan for that step and ask for a demonstration on its own matter rather than on sample documents.

The two headline prices also cover different things. The CoCounsel Legal price carries access to Westlaw and Practical Law content, while the Irys price covers its own research database. A firm that already licenses Westlaw should compare the incremental cost of CoCounsel Legal against the firm's current subscription rather than against the Irys headline price.

Should you choose Iqidis or CoCounsel?

The Iqidis vs CoCounsel decision comes down to whether the firm already relies on Westlaw and Practical Law, and whether the team wants a matter workspace or a task-driven assistant.

Choose Irys if

The firm wants published pricing, a trial it can start today, and research, drafting, and document analysis organized around each matter without a separate research subscription. Irys suits solo attorneys and small firms on Irys One or Irys Teams, and teams that need HIPAA-compliant handling for health-related matters.

Choose CoCounsel if

The firm already licenses Westlaw or Practical Law and wants AI grounded in that content, or it handles multistep research and document analysis at volume. CoCounsel Legal suits larger firms and legal departments that buy through Thomson Reuters and use iManage or NetDocuments.

Review contracts against your own positions

Research platforms answer legal questions; contract work also needs review against a team's standards. Spellbook helps lawyers review contracts against their own playbooks and market data, so first-pass review surfaces the terms that need a lawyer's attention.

Frequently asked questions

These are the questions buyers most often ask when comparing Iqidis vs CoCounsel, starting with the Iqidis rebrand and what each product costs.

Is Iqidis the same as Irys?

Yes. Iqidis, Inc. rebranded to Irys in March 2026. The product formerly called Iqidis is now Irys One, the website moved to irys.ai, and the legal entity remains Iqidis, Inc.

How much does Iqidis cost?

Irys One, the product formerly called Iqidis, costs $299 per month for one seat, or $3,049 per year billed annually. Irys Teams costs $329 per seat per month for 2 to 25 seats, and a capped Irys Lite plan costs $19.99 per month.

How much does CoCounsel cost?

CoCounsel pricing from the Thomson Reuters configurator depends on firm size, jurisdiction, and term. For a five-attorney firm on a one-year term, CoCounsel Essentials costs about $1,464 per month and CoCounsel Legal about $2,461.60 per month, roughly $293 and $492 per user.

Does CoCounsel offer a free trial?

CoCounsel does not offer a self-serve free trial. Evaluation runs through Thomson Reuters sales. Irys offers a 7-day trial without a credit card.

What AI does CoCounsel use?

Thomson Reuters announced in May 2026 that the next generation of CoCounsel Legal is rebuilt on Anthropic's Claude Agent SDK. CoCounsel Legal grounds that AI in Westlaw and Practical Law content.

Is CoCounsel a good program?

CoCounsel is a strong fit for firms that already rely on Westlaw and Practical Law, because CoCounsel Legal reasons from that content and adds Deep Research and large-scale document analysis. Firms without those subscriptions, or that want published pricing and a self-serve trial, can compare it against other CoCounsel alternatives, including Irys.
