Irys (formerly Iqidis) vs Microsoft CopilotOne assistant for the whole office. One system for the matter.

It sits inside Word, Excel, PowerPoint, Outlook and Teams, it draws on the firm's own Microsoft 365 content, and it inherits the tenant's identity, permissions and administration.

For a firm standardized on Microsoft, that is a real advantage. There is nothing new to procure, nobody new to onboard, and the assistant is already where the work happens.

It is a general productivity assistant, not a legal platform. Microsoft positions it that way itself, and the comparison below treats it that way rather than measuring it against a job it was never sold for.

The figure on its own business page is $32 per user per month for Microsoft 365 Business Premium with Copilot, paid yearly, and an annual commitment is stated. Copilot is sold inside a Microsoft 365 bundle rather than as a standalone legal seat, so the comparison is a bundle against a platform, not seat against seat.

Microsoft lists a free trial: yes, one month, converting to paid automatically. Read that sentence before you start it.

Irys One is publicly listed at $299 per month, with no per-token or per-query overage on the advertised plan. Irys Teams is $329 per seat per month for 2 to 25 attorneys. There is a 7-day trial with no credit card.

On sticker price the bundle wins, and it is worth saying plainly. The question is what each subscription is responsible for when the work is a matter.

No new vendor, no new login, no change management: the assistant appears inside the applications the firm opens every morning.

Tenant-native administration. Identity, device policy, data residency and compliance tooling are the ones the firm's IT team already operates, and Microsoft states that prompts, responses and Microsoft Graph data are not used to train its foundation models.

Breadth across the organization. Finance, marketing, operations and administration get the same assistant, which is a reasonable way to put capable AI on every desk at once.

Office-native output. It drafts in the file format the work ends in, and the firm's documents, mail and chat are already in reach without an upload step.

Microsoft's SOC 2 scope page lists Office 365 and does not name Copilot. Microsoft's ISO 27001 scope page does not name Copilot. On HIPAA the picture is different: Microsoft Copilot is named in Microsoft's HIPAA scope list.

Retention is an administrative decision, not a product default. No default period; admins set retention in Purview. Prompts are stored and searchable by eDiscovery. For a firm that handles privileged material, that is a governance question to settle before the first matter, not after.

Legal research is not part of the product. Microsoft does not publish a legal citator, and a general assistant that cannot check whether an authority is still good law should not be the last step before a filing.

Document execution is a separate purchase. Microsoft's own Copilot business pages do not offer electronic signature, so a signing tool remains a line item.

The next task picks up where the last one ended, instead of starting from an empty prompt beside an open file.

Output is source-linked, and Cite Check reviews the authorities behind it, so a lawyer can trace a material statement back to its source rather than taking an answer on faith.

Irys also lives inside Word. The difference is what comes with it: the add-in carries the matter into the document, rather than carrying only the document.

Built-in electronic signature covers execution without another subscription, and Workbench connects to Gmail, Google Drive, Calendar, Sheets, Outlook, OneDrive and Slack, preparing documents and email drafts across them with user approval rather than sending on its own.

The infrastructure around the models is Irys's own: agentic orchestration, structured matter intelligence and evaluation infrastructure built to plan and carry multi-step legal work. In Irys's internal evaluations on published legal benchmark tasks (Irys internal testing, July 2026), the Irys system scored above leading frontier-model baselines on legal work. Methodology available on request.

None of this says Copilot is weak. It says the legal structure, matter state, provenance, citation review and finished work product, is the part a productivity assistant was never asked to carry.

Take one real matter and run the same work through both tools, then answer these questions.

Choose Copilot when the priority is one assistant for the whole organization inside software the firm already owns. Choose Irys when the priority is legal work product: matters, citations, drafting and finished files, with the compliance scope named for the product you are actually buying.
