Definely

Definely is a suite of AI tools for lawyers creating, drafting, and reviewing complex contracts in Word. Read brings defined terms and cross-references into view for editing within a clause, and can produce a report of defined, undefined, and unused terms. Proof checks for incomplete information, inconsistent formatting, and spacing issues. Cascade analyzes how a contract change may affect clauses, definitions, and references. Enhance supports natural-language contract analysis and cites relevant clauses and definitions in its responses. Vault connects to a document management system to search and reuse precedent clauses and provisions. The homepage displays Microsoft Word, iManage, NetDocuments, and SharePoint as workflow integrations. Definely lists web, Windows, and macOS support and says its products serve law firms and in-house legal teams. Pricing is available on request; Mac users can start a free 14-day trial. Draft and Proof currently work in English and Swedish, and the maker says it does not purport to support documents drafted in other languages. The Trust Centre lists security and compliance items including ISO/IEC 27001:2022, SOC 2 Type 2, GDPR, ISO/IEC 42001:2023, and Cyber Essentials.

Definely brings contract navigation, proofreading, change analysis, and precedent search into a suite for legal teams. Buyers should check its language support and request pricing for their needs.

Definely is aimed at law firms and in-house legal teams handling complex contracts. Its tools may also suit users who need help navigating contract language, including people with visual impairment-related accessibility needs.

Definely is a contract-focused AI suite for lawyers who spend much of their day drafting and reviewing complex agreements in Microsoft Word. It suits law firms and in-house legal departments with established document-management workflows and precedent libraries. Its breadth is useful for repeatable review work, while the English-and-Swedish limitation and custom pricing make a careful fit assessment essential.

Overview

Definely combines contract navigation, proofreading, change-impact analysis, natural-language interrogation, and precedent retrieval. The tools are designed to keep lawyers close to the document rather than sending them to separate databases or repeated manual searches.

Workflow integrations shown by the company include Microsoft Word, iManage, NetDocuments, and SharePoint. Its Trust Centre lists ISO/IEC 27001:2022, SOC 2 Type 2, GDPR, ISO/IEC 42001:2023, and Cyber Essentials. Definely reports that its 2026 penetration test found no critical, high, or medium-severity vulnerabilities. Those credentials are relevant to sensitive legal work, but procurement teams should still match them to their own controls.

Key features

Read and Definitions Report

Read surfaces defined terms and cross-references in the clause being edited, so users can inspect or change linked language without leaving context. Its Definitions Report lists every defined, undefined, and unused term in a contract. That combination is particularly useful for long agreements where terminology errors are easy to miss in a linear read-through.

Proof

Proof automates checks for incomplete information, inconsistent formatting, and spacing problems. It can reduce a separate proofreading pass, although teams should treat flagged issues as review prompts rather than a substitute for legal judgment.

Cascade and Enhance

Cascade applies AI-powered impact analysis to show clauses, definitions, and references that may be affected by a change. This is valuable when an amendment could create knock-on edits elsewhere in a document. Enhance accepts natural-language questions and cites clauses and definitions in its answers, giving lawyers a way to interrogate a contract without constructing a manual search.

Vault and comparison tools

Vault connects to a document-management system for searching and reusing precedent clauses and provisions. Definely also supports clause comparison and redline suggestions. Together, these features favor teams that already maintain organized precedent collections and want retrieval and change review in the same workflow.

Formats, languages, and enablement

Microsoft Word and PDF are supported file formats. Draft and Proof currently work in English and Swedish; teams drafting in other languages should look elsewhere or confirm a workable scope before purchase. Downloads include a support hub with training videos, guides, and reference sheets, while pilots may include tailored onboarding and live training. Enterprise customers can receive dedicated support.

Pricing

Definely products use custom pricing. Products can be trialled or purchased through an account, and enterprise plans and customised pilots are available. Mac users can start a free 14-day trial. This approach suits firms that need a scoped deployment, integrations, or onboarding, but it gives smaller teams no published figure for budgeting or direct plan comparison. Confirm seat terms, renewal conditions, and which products are included before committing.

Platforms

Definely runs on macOS, Windows, and the web. Its integrations with Word, iManage, NetDocuments, and SharePoint are most relevant to organizations already using those systems.

Who it's for

Definely is aimed at law firms and in-house legal teams handling dense contracts. Its founders describe building it after encountering navigation difficulties in complex agreements, including accessibility needs related to visual impairment. That background makes context-preserving navigation a meaningful strength for reviewers who find cross-reference-heavy documents difficult to move through. Named customers include Dentons, A&O Shearman, DLA Piper, KPMG, Samsung, and BT Group.

Pros and cons

Pros

• Broad contract workflow: navigation, proofreading, impact analysis, natural-language answers, precedent search, comparison, and redline suggestions sit in one suite.
• Useful system connections: Word, iManage, NetDocuments, and SharePoint integrations can fit established legal-document processes.
• Enterprise-oriented assurance: the stated compliance portfolio and 2026 penetration-test result support security reviews.
• Adoption support: training materials, optional tailored pilots, live training, and dedicated enterprise support can ease rollout.

Cons

• Language coverage is narrow: Draft and Proof support English and Swedish, not documents drafted in other languages.
• No public price: custom quotes and account-based purchasing make early cost comparisons difficult.
• Best value depends on infrastructure: teams without compatible document-management systems or substantial precedent libraries may use fewer of Vault's benefits.

Verdict

Definely is a strong choice for legal teams that want connected Word-based drafting and review, especially where impact analysis, precedent reuse, and document-management integrations matter. Choose it when a tailored enterprise deployment and its supported languages match your workflow. Look elsewhere if you need broad multilingual drafting support, transparent self-serve pricing, or a lightweight free plan.
