Where Spellbook and Ivo Differ

Spellbook: Drafting and Market Comparisons in Word

Spellbook fits a buying decision centered on drafting, revising, and negotiating agreements in Microsoft Word. Its Market feature adds an external reference point: how a term compares with similar deals. For counsel assessing a counterparty's proposed position, that can inform the negotiation alongside the company's own risk tolerance.

Apply market data to the transaction in front of you. Check whether the comparison reflects the relevant agreement type, jurisdiction, and commercial circumstances before using it to support a fallback.

Ask and Associate also provide cited legal research within the drafting and review workflow, while Associate supports work across multiple documents. Its newer ACM offering is advertised for early access, so an evaluation that depends on contract management should establish which capabilities are available to your team. Keep currently available features separate from early-access commitments when comparing proposals.

Ivo: Review Informed by the Contract Portfolio

Ivo is relevant when a negotiation depends on what your company has agreed to before. Intelligence connects base agreements and amendments, extracts terms, and supports questions across the repository. Review uses playbooks and historical contracts to inform proposed changes.

For example, a team negotiating a renewal may need to understand both its standard position and concessions in the existing relationship. Ivo's portfolio approach gives that evaluation a different starting point from an external market comparison. Check the identified agreement family and the supporting passages before relying on the result.

Ivo Assistant adds cited legal research and regulatory analysis to that portfolio context. A team examining a regulatory change can research the rule and identify affected contract terms. Include the relevant jurisdictions and source-checking steps in the demonstration you request.

Why GC AI Is the Best Alternative for the Full In-House Workload

GC AI helps your team carry a matter through review, research, and advice to the business. At Liquid Death, General Counsel and Corporate Secretary Tiffany Lee uses GC AI for commercial contract review, regulatory trends, and assessing marketing concepts for legal risk.

GC AI is life-changing. It’s an indispensable tool for in-house practice.

Carry the Redline Through to a Business Decision

With GC AI for Word, you can draft, review, and revise the agreement where the negotiation happens. Playbooks apply your team's standards and fallback positions to the first pass, giving counsel a consistent starting point for judgment.

Consider this illustrative vendor-contract workflow. Supply the agreement and your approved liability positions, then use a Playbook to identify deviations. Ask GC AI to propose targeted edits and explain which issues need a business decision. If a proposed clause raises an enforceability question, use Research to investigate the governing law and check the cited authorities. Turn the reviewed analysis into a short message explaining the preferred position, an acceptable fallback, and any approval needed.

Counsel checks that the redline and explanation agree before sending either. An approved fallback can then become part of the team's maintained Playbook for future reviews. The process connects legal analysis with a usable handoff while keeping the decision with the lawyer.

Hayley McAllister, Senior Counsel and Head of Commercial Legal at Jasper, describes the Word add-in's role in her practice:

Once the Word plugin rolled out, I pretty much exclusively started using it for all of my redlining and contract review.

Find the Terms That Govern Today

The agreement in front of you may be only part of the record. A renewal, statement of work, or later amendment can change the obligation you need to assess.

Contract Intelligence connects related documents and brings the terms in force into a Current Terms view. Your team can ask questions across the portfolio, extract relevant provisions, and open the source passage behind an answer. That makes it useful for identifying which agreements warrant closer review when a business issue arises.

For a renewal assessment, inspect the original agreement and the amendments behind the current termination or pricing term. If an expected amendment is missing, obtain it before advising the business. A cited answer helps you inspect the record; counsel still determines whether that record is complete and supports the conclusion.

Support the Work Around the Contract

GC AI's Agent Connectors bring the surrounding communications into the work. In the vendor-contract example, connect the authorized email and file sources, then ask for the latest counterparty position, the current draft, and a proposed reply. Set sending actions to Needs approval so you can check the message and approve it in chat.

In-house advice also includes preparing for negotiations. Cameron Clark, Head of Legal at Arc'teryx, used GC AI to work through negotiation strategy before an asset purchase in Korea, including sensitive issues, acceptable ranges, and likely counterarguments.

It gave me a plan and the confidence to lead discussions with our CFO and GM of APAC.

GC AI pairs these workflows with attorney-led AI classes on prompting, Word, and Playbooks. Select classes are eligible for California MCLE credit, and Team plans include Solutions Attorney support. The practical benefit is help developing a repeatable way to use the platform across your department.

In GC AI's December 2025 structured survey of more than 100 active customers, respondents reported saving an average of 14 hours per user each week. These are self-reported customer outcomes, not a head-to-head test against Spellbook or Ivo.
