Pros & Cons

Pros

  • Deep Structural Review: Tracks definitions and cross-references through a contract and flags ripple effects when a clause changes, catching errors generic AI tools miss.
  • Native Microsoft Word Integration: Lawyers work in their existing environment rather than switching to a separate app or portal.
  • Trusted by Elite Firms: Used by 150+ law firms and in-house teams, including Magic Circle and White Shoe firms like A&O Shearman, Slaughter and May, DLA Piper, and Dentons.
  • Enterprise-Grade Security: SOC 2, GDPR, ISO 27001, and ISO 42001 compliance for large-firm and regulated-industry adoption.

Cons

  • No Public Pricing: All pricing requires a sales demo and custom quote, making it hard to budget or compare without contacting the vendor.
  • Contract-Review Focused: Not a full contract lifecycle management (CLM) platform, so larger organizations may still need separate tools for signing and repository management.
  • Limited Independent Rating Data: No single, well-populated public review aggregate (G2/Capterra) was available at review time to benchmark satisfaction at scale.

About Definely

Introduction

Definely is a London-based legal AI company, founded in 2017, that builds a suite of tools — Read, Proof, Cascade, Enhance, and Vault — for reviewing, proofing, and de-risking complex contracts directly inside Microsoft Word. It integrates with iManage, NetDocuments, and SharePoint, and is used by more than 150 law firms and in-house legal teams, including Magic Circle and White Shoe firms such as A&O Shearman, Slaughter and May, DLA Piper, and Dentons. The company has raised roughly $40 million to date, including a $30 million Series B in June 2025 backed by Revaia and Clio Ventures.

Contract Analysis

Definely's core strength is structured contract review: its Read and Cascade tools track definitions and cross-references through a document and flag the ripple effects when a clause changes, while Enhance layers AI-powered analysis on top to surface risk. Proof audits documents for drafting errors (undefined or unused terms, inconsistent numbering, broken cross-references) that are easy for a human reviewer to miss in long agreements.

Document Drafting

Because Definely lives inside Word, lawyers draft and revise in their normal environment rather than switching tools, and Vault adds secure indexing and precedent search so drafters can pull from prior firm or company documents while writing.

Pricing

Definely does not publish pricing; prospective customers must book a demo and receive a custom quote, which is typical for enterprise legal-tech sold to law firms and large in-house teams.

User Reviews and Ratings

Definely's individual products (Definely Draft, Definely Proof) are listed on G2, where user reviews highlight time saved catching drafting errors in long contracts, though no single aggregated public rating score was consistently available at the time of writing. Adoption by major law firms and continued enterprise-focused investment (Microsoft, Google, Clio Ventures) point to strong reception among its target market of large firms and corporate legal departments.

Verdict

Definely is a strong fit for law firms and in-house teams that live in Microsoft Word and need deep, structural contract review rather than a standalone CLM or chat-style assistant. It is less relevant for teams wanting an all-in-one contract lifecycle platform or transparent self-serve pricing.
