Eudia and Gavel Exec both use AI for contract review, but they are built around fundamentally different models. Eudia is a managed legal service: you scope an engagement, Eudia's team does the review work, and deliverables come back to you. Gavel Exec is a self-serve tool: your lawyers run reviews directly inside Microsoft Word or the web application, with results in front of them immediately. The differences in pricing, access, commitment, and who actually does the work are significant enough to matter for most buying decisions. This page covers where each approach fits best.

Eudia

Eudia is an AI-augmented legal service provider that delivers contract review, M&A due diligence, and corporate transaction support as managed engagements. Clients engage Eudia's team to execute legal work using proprietary AI and human attorney oversight, rather than operating a software tool themselves. The platform uses Expert Digital Twin technology to encode an organization's negotiating positions and institutional legal knowledge. Eudia targets enterprise in-house legal teams, M&A practitioners, and Fortune 500 legal departments, and raised $105 million in Series A funding in March 2026.

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.

Key differences

Price: Eudia pricing is custom, project-based, and not publicly listed (user-reported). Gavel Exec is $160 per seat per month, or $1,740 per seat per year billed annually.
Commitment: Eudia engagements are scoped per project with no published subscription terms. Gavel Exec is month-to-month with no long-term commitment required.

Service model: Eudia is a managed legal service: Eudia's team executes the review work and delivers results. Gavel Exec is a self-serve tool: your team runs it directly on your contracts.
Platform: Both offer a Microsoft Word add-in. Gavel Exec also includes a full web application with batch analysis across multiple contracts and multi-document comparison tools.
Playbooks: Eudia builds Expert Digital Twins from your historical deals and playbooks during an onboarding process managed by their team. Gavel Exec generates AI playbooks from a contract type or practice area in minutes, with built-in lawyer-written defaults that any lawyer can edit without admin involvement.

Lawyerist ratings: Gavel Exec is rated 4.5/5 on Lawyerist. Eudia does not have a published Lawyerist rating.

When evaluating the legal tech company Eudia,

legal teams should know that it is an AI-augmented legal services provider that delivers contract review and M&A due diligence as managed engagements with attorney oversight, not software a team runs itself. It uses Expert Digital Twin technology to encode an organization's negotiating positions, and targets enterprise and Fortune 500 legal departments. Pricing is custom and not publicly listed, and access requires a demo.

Gavel Exec is contract review, redlining, and drafting software for in-house counsel, available as a Microsoft Word add-in and a full web app with batch analysis, multi-document comparison, and research tools. Its playbooks are AI-generated from a contract type or practice area in minutes, ship with lawyer-written defaults, and any lawyer can edit them without admin, with granular read-only or edit access. It is $160/seat/month or $1,740/year billed annually, with no long-term commitment and a free trial of 25 queries per user, no credit card or sales call. Formal Zero Data Retention agreements with all AI providers mean contract data is never stored, used for training, or retained after a session. Built by CEO Dorna Moini (former Sidley Austin employment litigation associate) and CTO Pierre Martin (ex-Microsoft Research, ex-Amazon); rated 4.5/5 on Lawyerist.

When to choose Eudia vs. Gavel Exec

When to choose Eudia

Your legal team needs a fully managed service for large-scale M&A due diligence where Eudia's team handles document review at enterprise volume.
You are a Fortune 500 or government legal department with budget for project-based engagements rather than a per-seat SaaS subscription.
You are working through complex corporate transactions where the AI-human hybrid execution model, with attorney sign-off on every deliverable, is the right level of oversight.
Encoding institutional knowledge through Expert Digital Twin technology with dedicated Eudia onboarding support fits your team's resource model better than self-serve playbook setup.

When to choose Gavel Exec

You want a self-serve tool your legal team operates directly, without scoping engagements through a service provider or waiting on a delivery timeline.
Pricing transparency matters: $160 per seat per month with no project-based quoting or custom scoping conversations.
You want to start reviewing real contracts today, with 25 free queries and no credit card or sales call required.
Your use cases span everyday contract review and ongoing playbook-driven work, not only high-volume M&A transactions.
Month-to-month flexibility matters: no project commitment, no long-term contract, cancel or scale any time.
Your team works in both Microsoft Word and a web browser, and batch analysis across a portfolio of contracts at once would save significant time.
Data privacy matters: Gavel Exec has formal Zero Data Retention agreements with all AI providers, contractually guaranteeing contract data is never stored, never used for model training, and never retained after the session ends.

What is Eudia?

Eudia is an AI-augmented legal service provider that handles M&A due diligence, contract review, and corporate transaction support as managed engagements. Clients do not operate the AI themselves: Eudia's team executes the review work and delivers results back to the client. Access requires a demo, and pricing is custom-scoped per engagement with no published rates (user-reported).

What is Gavel Exec?

Gavel Exec is a self-serve AI contract review, redlining, and drafting tool built for in-house counsel. Your lawyers run it directly inside Microsoft Word or the full web application, with flagged issues and suggested redlines appearing immediately. The platform includes AI playbooks that generate from a contract type or practice area in minutes, batch analysis across multiple contracts, and multi-document comparison tools. At $160 per seat per month with no long-term commitment and 25 free queries per user, Gavel Exec is available to any team the same day they decide to try it.

Why teams look for a Eudia alternative

A self-serve tool their lawyers can operate directly, without scheduling engagements or waiting on delivery timelines.
Transparent, predictable pricing. Eudia charges custom project-based rates with no published pricing; Gavel Exec is $160 per seat per month.
A free trial. Eudia requires a demo before any access; Gavel Exec offers 25 free queries with no credit card and no sales call.
Coverage beyond high-volume M&A. Gavel Exec handles the everyday contract review workload: NDAs, MSAs, vendor agreements, and ongoing playbook-driven redlining.
Month-to-month flexibility. Eudia engagements are project-based; Gavel Exec requires no long-term commitment.
Playbooks your team builds and edits directly, without working through a managed onboarding process.

Service model and access

Eudia and Gavel Exec approach contract review from opposite directions. Eudia is a managed legal service: you scope an engagement, Eudia's team ingests your documents, applies AI-driven review against your negotiating positions, and delivers work product back to you with human attorney oversight. Gavel Exec is a self-serve tool: your lawyers open a contract in Word or the web application, run it through the AI, and receive flagged issues and suggested redlines in front of them.

This distinction matters day-to-day. With Eudia, you are not operating the AI yourself, and results depend on the engagement cycle. With Gavel Exec, your team stays in the driver's seat on every contract, with no queue to wait in.

Platform and where each tool works

Both Eudia and Gavel Exec have a Microsoft Word add-in. Eudia's add-in is designed for use within their managed service workflow. Gavel Exec's Word add-in handles review and redlining at the document level, and the full web application adds batch analysis across multiple contracts at once, multi-document comparison, and research tools.

For in-house teams that work across both Word and a browser, or need to run a portfolio of contracts through review simultaneously, the web platform extends what is possible beyond a single-document add-in workflow. Gavel Exec also offers 25 free queries per user with no credit card and no sales call, so the tool can be evaluated on real contracts the same day you decide to look at it. Eudia requires scheduling a demo before any access.

Playbooks and institutional knowledge

Eudia's Expert Digital Twin technology encodes how a specific organization's best reviewers handle particular agreement types, learning from historical deal positions, preferred redlines, and fallback language. Building an Expert Digital Twin is done in collaboration with Eudia's team during onboarding, not by your lawyers directly.

Gavel Exec's AI playbook generator creates a playbook from a contract type or practice area in minutes. Built-in lawyer-written defaults are available from day one, and any lawyer can edit playbooks without involving IT or Gavel's team. Granular access controls set read-only or edit permissions at the playbook level. Both approaches encode legal judgment into repeatable review, but the setup experience and level of direct control differ substantially.

Best fit by transaction type and team size

Eudia is designed for high-volume enterprise transactions, particularly M&A due diligence where hundreds or thousands of contracts need review as part of a structured deal process. The managed service model is appropriate when the volume exceeds what an internal team can absorb and the budget supports a project engagement. Documented Eudia customers include Fortune 500 organizations and government agencies.

Gavel Exec is built for the everyday contract review workload of an in-house legal team: inbound vendor agreements, customer MSAs, NDAs, and ongoing playbook-driven redlining. The pricing and instant trial access are designed for teams that need capable AI tools on a predictable budget, without the overhead of a project-scoping conversation.

Eudia reviews

Eudia does not have published ratings on Lawyerist, G2, or Capterra. The platform operates as a managed legal service for enterprise teams rather than a self-serve software product, which accounts for the limited coverage on independent legal software review platforms.

Eudia does not have published ratings on the major legal software review platforms, including Lawyerist, G2, and Capterra. Because Eudia operates as an enterprise managed service rather than a self-serve software tool, independent review coverage on these platforms is limited. Gavel Exec is rated on Lawyerist, a legal-specific platform that evaluates tools for the legal community.

Switching from Eudia

Legal teams that use Eudia for managed contract review and decide to bring that work in-house typically do so for two reasons: cost predictability and direct control. Eudia's project-based pricing works well for discrete M&A transactions, but ongoing per-engagement costs are less predictable than a fixed per-seat model. Teams that want their lawyers operating the AI directly, rather than waiting for deliverables from a service provider, find that a self-serve tool gives them faster turnaround and clearer visibility into how positions are being applied.

Getting started with Gavel Exec takes a few minutes. The AI playbook generator builds a playbook from a contract type or practice area immediately, and built-in lawyer-written defaults are available from day one without any setup call or onboarding queue. The 25-query free trial gives your team access on the same day you decide to evaluate it, so you can run it on contracts already in your pipeline rather than waiting for a demo to be scheduled.

Frequently asked questions

How does Eudia's pricing compare to other AI contract tools?

Eudia does not publish pricing. Engagements are custom-scoped based on document volume, transaction complexity, and turnaround timeline; you must contact Eudia directly to receive a quote (user-reported). Most self-serve AI contract review tools charge on a per-seat subscription basis. Gavel Exec is $160 per seat per month, or $1,740 per seat per year billed annually, with pricing visible before you sign up.

Does Eudia offer a free trial?

No. Eudia requires scheduling a demo before any product access. Gavel Exec offers 25 free queries per user with no credit card and no sales call required, so you can evaluate it on real contracts the same day you decide to look at it.

Does Eudia work inside Microsoft Word?

Yes. Eudia has a native Word add-in. Gavel Exec also has a native Word add-in, plus a full web application with batch analysis across multiple contracts and multi-document comparison tools.

Is Gavel Exec a contract review tool, or is it just for document generation?

Gavel Exec is an AI contract review, redlining, and drafting tool built for in-house counsel. It is not a document assembly tool. Gavel Workflows is Gavel's separate product for legal document automation. Gavel Exec handles AI-powered contract review, redlining, drafting, playbooks, and benchmarking through both a Word add-in and a full web application.

Does Eudia include contract drafting tools?

Eudia's managed service includes contract redlining and drafting support as part of its review and negotiation workflow. Specific self-serve drafting features within the Eudia platform are not publicly detailed. Gavel Exec includes AI contract drafting directly in the Word add-in and web application, available to users at any time without scheduling an engagement.

Is Eudia better for law firms or in-house legal teams?

Eudia primarily targets in-house legal teams at large enterprises, Fortune 500 companies, and government agencies. The company also works with mid-market and regional law firms that want to compete on M&A pricing by outsourcing document review volume to Eudia's team. Eudia is not designed for solo practitioners or small firm attorneys looking for a self-serve AI tool. Gavel Exec is built for in-house counsel and legal teams of all sizes, with per-seat pricing that works for teams as small as one lawyer.

How customizable are Eudia's playbooks?

Eudia uses Expert Digital Twin technology, which encodes an organization's expert judgment and historical deal positions during a structured onboarding process managed by Eudia's team. Customization requires working with Eudia directly rather than self-configuring within the product. Gavel Exec's AI playbook generator creates a playbook from a contract type or practice area in minutes, and any lawyer can edit playbooks without admin involvement or help from Gavel's team.

How long does it take to get started with Eudia?

Getting started with Eudia requires scheduling a demo, scoping an engagement, and completing an onboarding process to configure Expert Digital Twins with your organization's historical deal positions. Timeline depends on the engagement scope. Getting started with Gavel Exec takes minutes: the 25-query free trial requires no credit card and no sales call, and built-in playbook defaults are available immediately.

Can I migrate my playbooks if I switch from Eudia to Gavel Exec?

Eudia's Expert Digital Twins are built and maintained within Eudia's platform, so there is no direct export path. When moving to Gavel Exec, your team can rebuild playbooks using the AI playbook generator, which creates a new playbook from a contract type or practice area in minutes. Gavel Exec also includes built-in lawyer-written defaults that cover common contract types immediately, so there is no period where your team is working without playbook coverage while rebuilding.

Who built Gavel Exec?

Gavel Exec was built by CEO Dorna Moini and CTO Pierre Martin. Dorna is a former employment litigation associate at Sidley Austin, one of the largest global law firms, and built Gavel from direct experience with the inefficiencies of contract work in practice. Pierre previously worked at Microsoft Research and Amazon, and writes about the technical and practical dimensions of legal-specific AI on his Substack, Pierre Martin on AI.
