LegalOn vs. Gavel: Which Contract AI Platform Fits Your Workflow?

LegalOn and Gavel both support AI-assisted contract review and drafting, but their platforms extend in different directions.

LegalOn combines contract review with attorney-built and custom Playbooks, Matter Management, intake, Vault contract intelligence, and broader in-house legal workflows. Gavel combines precedent-based contract review through Gavel Exec with conditional-logic document automation through Gavel Workflows.

This guide compares LegalOn and Gavel across contract review, Playbooks, market context, adjacent workflows, security, and pricing. The comparison is written for the in-house legal team weighing the two.

Key Takeaways

1. LegalOn pairs AI contract review with an attorney-built Playbook library, custom Playbooks, Matter Management, intake, and post-signature contract intelligence.
2. Gavel Exec applies a team's own Playbooks, precedent, and deal history inside Microsoft Word, and also supports drafting and market-data benchmarking.
3. Gavel Workflows solves a different problem from contract review, turning structured intake into finished documents. It suits repeatable, form-driven paperwork rather than heavily negotiated agreements.
4. LegalOn publishes no rates and quotes the full platform around team size and the capabilities a team needs. Gavel publishes pricing for both Gavel Exec and Gavel Workflows.
5. LegalOn is SOC 2 Type II certified and holds ISO 27001 and ISO 27017 certifications. Gavel publishes SOC 2 Type II certification for Gavel Exec, together with zero-data-retention agreements covering the AI providers it uses.
6. Both vendors offer regional data hosting. Gavel defaults to the United States on Amazon Web Services, with other regions available, and LegalOn provisions dedicated environments in the United States, Japan, Germany, or Singapore.

What Is LegalOn?

LegalOn is an AI platform for in-house legal teams covering contract review, drafting, legal assistance, Matter Management, intake, and post-signature contract intelligence.

LegalOn Contract Review

LegalOn reviews and redlines agreements against both attorney-built and organization-specific standards, with the proposed changes reviewed and accepted by a lawyer before the document goes back out. Review and drafting run inside Microsoft Word and in a browser, and the platform works with both .docx and PDF files.

Each Playbook in the attorney-built library is written for a specific contract type and negotiating position, and LegalOn maintains the set as laws and standards change. Teams that need their own standards can build custom Playbooks, or use the Playbook Agent to convert existing legal guidance into reusable review instructions. The ready-made library now runs to more than 135 Playbooks across major contract types.

That library covers the issues that recur inside those contract types. Unusual or heavily bespoke agreements still need custom Playbooks written against the team's own preferred and fallback positions, which is work the ready-made library does not remove.

LegalOn Beyond Contract Review

LegalOn also extends into post-signature contracts and broader legal operations.

Vault turns signed contracts into searchable information about terms, obligations, renewals, and other contract data. Vault Projects applies a defined set of analysis criteria across a whole contract set at once.

The Productivity Suite adds a second layer on top of contracting, extending the platform from contract review into legal matter management:

1. Matter Management: legal requests, intake, triage, and workload visibility in one place.
2. Matter Intelligence: context and language surfaced from past matters.
3. Intake channels: email, web forms, and Slack.

Vault reports on what has been loaded into it. A repository missing executed agreements reports on an incomplete set, so the value of the extraction depends on getting signed contracts into Vault first, including the legacy agreements that predate the rollout.

What Is Gavel?

Gavel offers two products that address different types of legal work.

Gavel Exec focuses on AI-assisted contract review, redlining, and drafting. Gavel Workflows focuses on document automation, turning structured inputs into finished legal documents. The two products are sold separately, and a team can buy either one on its own without taking the other.

Relativity announced its acquisition of Gavel on June 12, 2026, saying it planned to extend the Relativity legal-data platform into Microsoft Word drafting, review, and document automation. Relativity said its immediate focus was continuity for customers, and that it intended to maintain regular operations at Gavel while bringing the capabilities into RelativityOne over time. Gavel continues to offer Gavel Exec for contract review and Gavel Workflows for document automation.

Gavel Exec

Gavel Exec is precedent-based contract-review software that runs inside Microsoft Word and online. Gavel Exec covers three jobs:

1. Review and redlining: entire agreements marked up against the team's Playbooks, precedent, deal history, and negotiation positions, with a lawyer accepting the proposed changes before they are sent.
2. Drafting: new clauses and contract language, plus rewrites of language already in the document.
3. Market benchmarking: clause language compared with market data to surface positions that may warrant attention during negotiation.

Benchmark context depends on the comparison dataset behind it, and it does not by itself resolve a negotiation position. A term sitting outside the market range can still be the right term for a particular counterparty, and that call stays with the lawyer running the deal.

Gavel Workflows

Gavel Workflows addresses document automation rather than the review of incoming agreements.

Gavel Workflows lets legal teams build questionnaire- and logic-driven workflows that turn structured information into finished documents, which a lawyer then reviews before use. The product is designed for repeatable document generation, including estate planning, real estate, and other form-driven legal work.

Gavel Workflows suits repeatable, form-driven documents and is a poor fit for bespoke or heavily negotiated agreements, where the terms are settled through negotiation rather than through an intake form.

Capabilities

Commercials and Ownership

What Are the Main Differences Between LegalOn and Gavel?

1. Their Review Standards Start From Different Places

Both LegalOn and Gavel Exec can review contracts against a team's own Playbooks.

LegalOn also provides a ready-made standards library. The LegalOn platform includes more than 135 attorney-built Playbooks, and teams can layer their own preferred and fallback positions on top of those standards.

Gavel Exec review draws on the organization's Playbooks, deal history, preferred language, and negotiation stance, so a team that has not yet recorded those positions gives the review little to work from. On Gavel Exec, writing those positions down is the first setup step. On LegalOn, the attorney-built library stands in until a team writes its own.

2. They Extend Beyond Review in Different Directions

LegalOn extends contract review into broader in-house legal operations.

Vault manages post-signature contract intelligence, while Matter Management connects legal requests, intake, triage, workload, and matter context.

Gavel extends in another direction through Gavel Workflows. Rather than managing the wider legal request lifecycle, Gavel Workflows automates the creation of repeatable documents from structured intake.

3. Their Market Context Is Different

Gavel Exec has a dedicated market-benchmarking capability that compares clause language with market data and can surface off-market positions during review for a lawyer to weigh.

The LegalOn contract-review model uses a different type of reference point, combining attorney-built Playbooks, organization-specific standards, jurisdiction-specific guidance, and market-standard templates.

A Playbook expresses a review position or standard, while market benchmarking shows how terms compare with a broader dataset.

4. Their Security and Data-Handling Programs Differ

LegalOn is SOC 2 Type II certified and holds ISO 27001 and ISO 27017 certifications. The LegalOn Azure OpenAI environment is configured so that customer data is not used to train models and is not retained for abuse monitoring or debugging.

Gavel publishes SOC 2 Type II certification for Gavel Exec and 256-bit AES encryption for data at rest, together with zero-data-retention agreements covering the AI providers it uses, which means those providers do not store the content submitted to them.

The two programs are scoped differently, and the difference is worth confirming during a security review.

5. Both Offer Regional Data-Hosting Options

Both vendors publish regional hosting options, reached from different starting points. LegalOn added dedicated environments in the European Union and Singapore alongside the existing United States and Japan infrastructure. Gavel reaches those regions through AWS, the infrastructure the platform already runs on.

1. LegalOn: the European Union environment is hosted in Germany, and LegalOn states that customer data in a regional environment remains in region both at rest and in transit.
2. Gavel: Gavel publishes United States AWS infrastructure as the default, with hosting also available in the European Union, Canada, Australia, and other AWS regions.

Gavel defaults to United States AWS hosting and publishes other AWS regions as options, while LegalOn provisions a dedicated environment in the region the team selects. Neither vendor publishes a process for moving an existing environment to another region, so the region is worth settling during procurement.

How Do LegalOn and Gavel Compare on Pricing?

LegalOn and Gavel use different commercial models.

LegalOn publishes no rates. LegalOn prices the full platform around a team's size and the capabilities it needs, then quotes each team individually, so a comparable number has to come from a quote rather than from a published price list. The packages build on each other:

1. Core Review: AI contract review, redlining, drafting, and the attorney-built Playbook library.
2. Contracting Suite: Core Review plus custom Playbooks, the Vault repository, and contract-set analysis.
3. Productivity Suite: the Contracting Suite plus Matter Management, the Intake Agent, the Triage Agent, and Matter Intelligence.

Gavel Exec publishes per-user monthly pricing with a discounted annual rate, and team pricing for 10 or more seats. New users can currently start with 25 free queries and no credit card, which makes a hands-on evaluation possible without a sales conversation.

Gavel Workflows is priced separately from Gavel Exec, across published tiers from Lite through Enterprise, with rates starting under 100 dollars per month. Each paid tier carries separate limits on builder seats, active workflows, and monthly sessions, so the right tier depends on document volume as well as headcount.

The pricing models cover different product scopes. Gavel prices each product on its own, while the LegalOn packages progressively add custom Playbooks, Vault, contract-set analysis, Matter Management, intake, and triage. LegalOn also currently publishes a 14-day free trial, with onboarding included.

Where Spellbook Fits

Spellbook is a commercial-contract specialist tool rather than a matter-management or document-automation platform. Three capabilities bear on this comparison, and all three run inside Microsoft Word:

1. Review of commercial agreements: the Review feature supports custom Playbooks, suggested redlines, comments, and lawyer approval of proposed changes.
2. Drafting from precedent: the Draft feature creates and revises contract language using the active agreement, precedent, and saved clauses.
3. Comparison of terms with market standards: the Compare to Market feature compares contract terms with data from 20M+ real market contracts across 270+ clause types, filtered by industry, jurisdiction, and deal type.

Spellbook focuses on commercial drafting, review, negotiation, custom playbooks, and external contract-market data.

Choosing Between LegalOn and Gavel

Once the review capability LegalOn and Gavel share is set aside, the decision turns on criteria a team can check against its own situation.

1. The extension the team actually needs: matter intake, triage, and post-signature contract intelligence point to LegalOn, while generating repeatable documents from structured intake points to Gavel Workflows.
2. Whether the team's positions are already written down: Gavel Exec works from the Playbooks, precedent, and negotiation positions a team has recorded, so a team starting without them can review against the LegalOn attorney-built library on day one instead.
3. The scope the security review has to cover: the Gavel SOC 2 Type II certification is published for Gavel Exec, so a team buying both Gavel products should confirm the scope that covers Gavel Workflows.

A review-only requirement is also worth testing against other Gavel alternatives before committing to either direction.

Frequently Asked Questions

Is Gavel Owned by Relativity?

Yes. Relativity announced the acquisition on June 12, 2026, and said it planned to extend the Relativity legal-data platform into Microsoft Word and legal drafting workflows. Relativity also said it intended to maintain regular operations at Gavel while bringing the capabilities into RelativityOne over time.

What Is the Difference Between Gavel Exec and Gavel Workflows?

The two products address different workflows and are licensed separately:

1. Gavel Exec: AI-assisted contract review, redlining, drafting, Playbooks, and market benchmarking in Microsoft Word and on the web.
2. Gavel Workflows: document automation that uses structured intake and conditional logic to generate repeatable legal documents.

The products can complement each other on a team that both reviews incoming paper and generates a high volume of standard documents.

How Do LegalOn and Gavel Apply Playbooks?

Both products can apply organization-specific review standards.

LegalOn also provides an attorney-built Playbook library that teams can use before creating their own standards. Gavel Exec works from the team's own Playbooks, precedent, negotiation positions, and deal history, so the review reflects the standards the team has recorded.
