Kira and Gavel Exec are two AI contract review tools that often come up in the same evaluation. Both use AI to extract provisions, flag risk, and support customized review workflows, but they are built for different buyer profiles. Kira is enterprise software built for high-volume M&A due diligence at large law firms. Gavel Exec is built for in-house counsel and legal teams that need fast, accurate contract review without an enterprise procurement process. This page covers their features, pricing, platform access, and the key differences a buyer needs to know before deciding.

Kira

Kira uses a combination of proprietary trained AI and generative AI to extract data from contracts across 40+ languages, with 1,400+ built-in smart fields covering common clauses and data points. The platform is web-based, designed for high-volume M&A due diligence and contract review at law firms and corporate legal departments. Lito, a bundled Word and Outlook agent, handles smaller in-document review tasks and is included in the Kira subscription.

Gavel Exec

Gavel Exec is AI contract review, redlining, and drafting software for legal teams. It works in Microsoft Word and online, so attorneys can review contracts inside Word or use browser-based workflows for broader contract analysis.

Gavel Exec supports playbook-based review, redlining, drafting, benchmarking, batch analysis, and multi-document comparison. Playbooks can be generated with AI, built from uploaded files, created manually, or started from built-in playbooks created by practicing attorneys. Gavel Exec publishes pricing at $160 per user per month or $1,740 per user annually, and offers 25 free queries per user with no credit card required.

When to choose Kira vs. Gavel Exec

When to choose Kira

Your firm is in the Am Law 100 or a large global law firm with an existing Litera relationship and IT resources to manage enterprise onboarding.
Your primary use case is high-volume M&A due diligence: processing hundreds or thousands of documents across a single deal under tight deadlines.
You need multi-language contract review at scale across 40+ languages for cross-border transactions.
Enterprise governance controls matter: your firm needs the ability to toggle GenAI on or off per project to meet client or regulatory requirements.
Your legal ops team can dedicate time to building and maintaining custom ML fields for proprietary or highly specialized clause types.

When to choose Gavel Exec

You are in-house counsel or part of a corporate legal team reviewing individual contracts, not bulk due diligence batches.
You want to start immediately: the free trial requires no credit card and no sales call, and you can be reviewing contracts within minutes.
You need a native Word add-in that integrates with your existing drafting workflow, not a companion app layered on top of it.
Playbook flexibility matters: you want AI-generated playbooks or built-in lawyer-written defaults you can edit yourself without involving an admin.
Month-to-month pricing with no annual commitment fits your team's budget cycle or procurement process.
Data security is non-negotiable: Gavel Exec has formal Zero Data Retention agreements with all AI providers, contractually guaranteeing your contract data is never stored, used for training, or retained after the session ends.

Side-by-side comparison

Kira does not publish pricing; access requires a demo request, and contracts are annual enterprise agreements. Third-party sources report starting costs of $30,000 to $60,000 per year for mid-market firms (user-reported). Gavel Exec is $160/seat/mo with no long-term commitment. Both tools include Word integration, though through different approaches: Kira is a web platform with Lito, a bundled Word and Outlook agent, for in-document tasks, while Gavel Exec is a native Word add-in that also offers a full web application for batch analysis, multi-document comparison, and research.

What is Kira?

Kira, owned by Litera, is contract analysis and data extraction software. It helps law firms identify and pull specific provisions from large volumes of contracts, primarily for M&A due diligence, using 1,400+ lawyer-trained smart fields and bulk review across 40+ languages.

What is Gavel Exec?

Gavel Exec is contract review software for in-house counsel and legal teams. It helps legal teams draft, review, redline, and benchmark contracts using AI playbooks, and runs as a native Microsoft Word add-in (Mac, Windows, and Word for the web) plus a full web app for batch analysis and multi-document comparison.

Platform and access

Kira is a web-based platform for project-based review: upload a batch of contracts, run analysis, review the output in an analysis grid, and export to Word or Excel. Lito, a Word and Outlook agent bundled with Kira, handles smaller in-document tasks like NDA checks, redlines, and term reviews. Lito and the core Kira platform are currently separate, with integration on the roadmap.

Gavel Exec works the other way around. Most users start in the native Word add-in, reviewing and redlining without leaving the document. The web app handles batch analysis, multi-document comparison, and research. Both are included in the subscription. The distinction matters for teams that live in Word: Kira's Word access is through Lito, a companion tool, while Gavel Exec's Word add-in is the core product.

Playbook flexibility and custom fields

Kira's Quick Study lets users train custom machine learning fields by highlighting sample language, with no coding and new fields in under an hour. It suits firms reviewing proprietary or non-standard clauses, but fields are trained from scratch with no lawyer-written defaults to start from.

Gavel Exec goes the opposite direction. AI-generated playbooks can be created in minutes from a contract type or practice area, and built-in lawyer-written defaults cover common scenarios out of the box. Any lawyer can edit a playbook without admin involvement, with granular read-only or edit access. Teams that want to start reviewing immediately reach productivity faster with Gavel Exec's defaults; teams with highly specialized deal types may prefer Kira's ML training.

AI contract review and drafting

Kira is built for extraction at scale: identifying and pulling provisions from large volumes of contracts with high accuracy, especially in M&A due diligence under deadline. Its 1,400+ smart fields cover common clauses across 40+ languages, Smart Summaries generate plain-language summaries, and GenAI fields answer natural language questions across documents without training.

Gavel Exec covers the full contract workflow on individual contracts: review, redline, draft, and benchmark. The AI surfaces risk, suggests redlines, and checks against a playbook in the same Word document, plus multi-document comparison and research in the web app. For in-house lawyers reviewing one contract at a time, Gavel Exec covers the workflow. For firms processing hundreds of documents in one deal, Kira's batch review and analysis grid are built for that scale.

Switching from Kira

Lawyers and legal teams switching from Kira most often cite cost and access. Kira is built around annual enterprise contracts with pricing that starts at tens of thousands of dollars per year (user-reported), and onboarding typically requires dedicated IT and legal ops resources. For in-house teams or smaller legal departments that need accurate contract review without an enterprise procurement cycle, that overhead is a barrier. Gavel Exec is month-to-month with no long-term commitment, and the free trial starts without a sales call.

Migration is straightforward. Gavel Exec's AI playbook builder generates playbooks from a contract type or practice area in minutes, and built-in lawyer-written defaults cover the most common review scenarios without any setup. Teams that built custom fields in Kira's Quick Study can typically replicate their review criteria in Gavel Exec on the day they start. There is no data to transfer and no implementation project to manage. Legal teams that have finished an enterprise contract term and want a more accessible tool can be fully operational in hours.

Third-party sources report starting costs of roughly $30,000 to $60,000 per year for mid-market firms (user-reported), and there is no publicly available self-serve trial.

Does Kira offer team or volume discounts?

Kira's pricing is negotiated per organization, so volume terms are part of the contract discussion. Gavel Exec offers discounted pricing for teams with 10 or more seats and for existing Gavel Workflows customers.

Does Kira work in Microsoft Word, in a browser, and on Mac and Windows?

Kira's main platform is web-based and runs in any modern browser on Mac or Windows. Its Word access comes through Lito, a Word and Outlook agent bundled at no extra charge for in-document tasks like NDA review, playbook checks, and redlines. Gavel Exec is a native Microsoft Word add-in on Mac, Windows, and Word for the web, plus a full web app with batch analysis, multi-document comparison, and research.

How customizable are Kira's playbooks?

Quick Study lets users train custom machine learning fields by highlighting sample language, with no coding and new fields typically in under an hour. There are no pre-built lawyer-written defaults; users build from scratch or expand on Kira's 1,400+ smart fields. Gavel Exec includes AI-generated playbooks, built-in lawyer-written defaults, and manual build options, all editable by lawyers without admin access.

Can Kira handle batch analysis and contract drafting?

Batch review across large document sets is Kira's primary use case, built for due diligence projects with hundreds or thousands of contracts. Drafting is not its focus; Lito can assist with in-document edits, but Kira is positioned as an extraction and review tool. Gavel Exec covers AI drafting and redlining alongside review and playbooks, and includes batch analysis and multi-document comparison in the web app.

How long does it take to get started, and can I migrate my playbooks?

Getting started with Kira means scheduling a demo, receiving a quote, and completing enterprise procurement; small-firm implementation is estimated at 4 to 6 weeks by third-party sources. Custom Quick Study fields use Kira-specific models that cannot be directly exported. With Gavel Exec, the free trial is available immediately, and most teams rebuild their review criteria in minutes using the AI playbook generator, with lawyer-written defaults covering common scenarios on day one.

Who built Gavel Exec?

Gavel Exec was built by CEO Dorna Moini, a former employment litigation associate at Sidley Austin, and CTO Pierre Martin, formerly of Microsoft Research and Amazon, who writes "Pierre Martin on AI" on Substack. It is designed by people who have practiced law and built AI systems at scale.

Does Kira or Gavel Exec have better reviews?

Kira holds 4.7/5 on Capterra (3 reviews) and 7.6/10 on TrustRadius (27 reviews); no Lawyerist rating was found for Kira. Gavel Exec holds 4.5/5 on Lawyerist. Review samples are small for both, so trying each tool directly is the more reliable comparison for most buyers.
