Weagree vs. Gavel Exec: Free AI Review Add-in or a Supported Word Tool?

How do Weagree and Gavel Exec work in Word?

Both run as a panel next to the contract in Microsoft Word. Weagree’s AI-contract review playbooks add-in loads a playbook, rates every clause on four risk levels, flags missing clauses and proposes fallback wording. Its “surgical redlining” changes the counterparty’s clause as little as possible, and you apply each change as a tracked change, with or without a Word comment. Seven built-in prompts check definitions and cross-references, summarise, translate and draft clauses, and an AI chat answers questions about the open document.

Gavel Exec is a Word add-in for AI contract review and drafting. Ask it to redline a draft to market terms or to your positions, or run a playbook: each rule passes or fails, failed rules come with a reason and proposed changes, and suggestions go into the document as tracked changes you accept or reject. A web app at exec.gavel.io runs analysis and benchmarking without a download.

Does Weagree’s add-in work on Mac and Word for the web?

Yes. Weagree says the add-in works in Word for Windows, Word for Mac and Word for the web, with settings synced across them; it doesn’t publish minimum Word versions. Gavel Exec runs in Word for Windows, Word for Mac (2016 or later), Word on the web and Microsoft 365.

How do the playbooks compare?

A Weagree playbook holds your position for each clause with several fallback levels, risk ratings from acceptable to dealbreaker, guidance on when to use each fallback, pre-drafted comments and clause dependencies. The add-in builds one from a model contract you upload, and Weagree’s playbook page says reviewing a basic AI-generated playbook takes under an hour, while fuller ones can take a day. Playbooks support any review language. Sharing playbooks across a team and syncing with your clause library are part of the paid Weagree Wizard, not the free add-in.

Gavel Exec starts from built-in playbooks for agreements such as NDAs, MSAs, DPAs and vendor agreements. You add rules in plain language or generate them from checklists, spreadsheet playbooks or signed agreements, and playbooks can be shared, exported and imported. Exec also benchmarks each clause against the market for a chosen jurisdiction, industry and company size.

Illustration: a distributor’s draft, reviewed for the supplier

You act for a manufacturer. The distributor’s draft grants it exclusivity across the EU with no purchase commitment. Your playbook allows exclusivity only against an annual minimum purchase volume, with non-exclusive rights as the fallback. The proposed redline adds the minimum volume and lets the supplier switch the appointment to non-exclusive if the distributor misses it. You decide whether to send that, offer the fallback or call the client first. By hand, this is a clause-by-clause read against a checklist. This illustrates the workflow both vendors describe; we didn’t run it in either product.

How much does Weagree cost vs. Gavel Exec?

Weagree’s add-in costs nothing from Weagree: no subscription, no time limit and no cap on reviews or playbooks. You pay your AI provider instead. Weagree puts that at 15 to 20 euros a month for the provider’s plan, plus about 1.20 to 4 euros per contract reviewed in API fees (its estimate, March 2026). The Weagree Wizard, its contract automation and CLM platform, is licensed per user type, SaaS or perpetual, and its price is not published.

Gavel Exec costs $160 per user per month, or $1,740 per user per year, with 1,000 completions a month, after 25 free queries per user with no credit card. Team pricing is available for 10 or more seats. See Gavel Exec pricing.

Is Weagree’s AI contract review add-in free?

Yes, from Weagree: no subscription, no time limit and no volume cap. You need your own API key from OpenAI, Anthropic, Google or another supported provider and pay that provider’s fees, which Weagree estimates at 1.20 to 4 euros per contract reviewed. You accept an “as is” disclaimer and may not resell the add-in.

How much does the Weagree Wizard cost?

Weagree doesn’t publish prices for the Weagree Wizard; it is quote-based. Licences are per user type (lawyer, business-limited and single-template users), as SaaS or perpetual, and approvers are free of charge. Connecting the add-in to the platform needs a Weagree Wizard subscription.

Data security: your own AI key or Gavel’s agreements

Weagree’s add-in runs its reviews through the AI provider whose API key you connect, and stores that key encrypted on your laptop. Weagree doesn’t publish how the add-in handles document text, so check that provider’s API data terms before you review client contracts. The Weagree Wizard platform is hosted in the Netherlands by default, can be installed on-premise, and encrypts contracts at rest and in transit. Weagree’s security page says it stopped certifying under ISO 27001 as of October 2026 while keeping the controls; its datacentre is ISO 27001 certified and audited under ISAE 3402 Type 2.

Gavel Exec is SOC 2 Type II certified, and Gavel’s Zero Data Retention agreements mean its AI providers don’t store your data or train on it. Data is hosted on AWS in the US by default, with EU, Canada and Australia hosting available. Read Gavel’s security practices.

Which AI model does Weagree use?

The one you choose. Weagree’s add-in works with any LLM with a compatible API, including OpenAI (GPT-4 or later), Anthropic Claude and Google Gemini, using your own API key. Gavel Exec includes its AI models, so there is no key to manage.

Is Weagree ISO 27001 certified?

Not any more. Weagree says that as of October 2026 it discontinued certifying its information security management system under ISO 27001, 27017 and 27018, while keeping the controls. Its hosting datacentre is ISO 27001 and ISO 27017 certified and audited under ISAE 3402 Type 2.

Does Gavel Exec train AI models on my contracts?

No. Gavel says it does not use customer data, prompts or document content to train AI models, and it has Zero Data Retention agreements with its AI providers, including OpenAI.
