Irys vs Spellbook
Word-native contract AI, or a platform built around the matter?
Spellbook is a focused contract tool that lives where transactional lawyers already work. Irys is a matter platform that spans research, drafting, review, and finished work product. Here is a straight comparison, and a way to test both.
Who Spellbook is for
Spellbook is a contract-centric legal AI product built around Microsoft Word. Its public materials document contract drafting, review, redlining, clause work, playbooks, Associate workflows for multi-step contract tasks, and tabular extraction across sets of agreements. It also offers a Google Docs interface, document repositories, and team controls that govern access to playbooks, workflows, and library folders.
Spellbook can pull documents from OneDrive, SharePoint, Dropbox, Google Drive, and iManage. The iManage connection is documented as manual document selection rather than a persistent repository sync. Spellbook does not position itself as a comprehensive case-law research system. If your practice is mostly contracts and your lawyers live in Word, Spellbook is a serious candidate and deserves a real evaluation.
Verified pricing, as of August 3, 2026
Spellbook's standard pricing is not publicly listed. A self-service trial is available. The clearest publicly documented usage term: Tabular Reports includes 500 documents per account at no additional cost, and additional documents may incur fees. Ask Spellbook what a quote includes, what allowances apply, and what changes at renewal.
Irys publishes its pricing. Irys One is $299 per month for an individual attorney, with no per-token or per-query overage on the advertised plan. Irys Teams is $329 per seat per month for teams of 2 to 50 attorneys. Enterprise pricing is custom. The 7-day trial requires no credit card.
What Spellbook does better
Spellbook offers one of the deepest Word-native contract experiences on the market. If your goal is AI assistance inside the redline itself, with minimal behavior change for lawyers who spend their day in Word, that focus is an advantage, not a limitation.
Its playbooks and Associate workflows are built specifically for contract review at volume, and its tabular extraction is designed for pulling terms across large sets of agreements. A purely transactional team that measures output in markups and turnaround time may find Spellbook's specialization exactly right.
What Irys does differently
Irys is built as a matter platform rather than a contract tool. Research, drafting, and document review share the same matter context, so the facts, documents, and sources you establish in one task carry into the next instead of restarting with every file. Output is source-linked, so you can check where a statement came from.
Irys works beyond the document editor. The Irys Word add-in brings the platform into Word for lawyers who draft there. Workbench, currently in beta, can take connected actions across applications like email, files, and calendars, and it requires user approval rather than acting autonomously. Built-in e-signature means a finished document can go out for execution without another subscription.
The commercial model is also different. Irys publishes its prices, offers a 7-day trial with no credit card, and charges no per-token or per-query overage on the advertised Irys One plan. You can evaluate the product on a real matter before talking to anyone.
How to evaluate both: run the same matter through each
Can it locate the exact source behind a factual statement it makes?
Can it carry context from a contract review into a later drafting or negotiation task without re-uploading and re-explaining?
Can it work across email, files, research, and Word without manual copying between windows?
Can it produce a usable file, not just chat text, and get that document signed?
Can teammates work in the same governed workspace with appropriate permissions?
What happens when the matter contains hundreds of documents rather than one agreement?
What is excluded from the quoted price, and what document, usage, or feature allowances apply?
What happens to the price at renewal?
Can you run a real matter during the trial before signing a longer agreement?
The bottom line
If your firm's work is contracts and your lawyers live in Word, Spellbook is a credible, focused tool and you should test it. If your work spans research, litigation, or multiple practice areas, or you want matter context, connected application actions, and finished work product on a published price, Irys is built for that broader job.
