What is Definely?
Definely is an AI legal document drafting tool that integrates directly into Microsoft Word, giving lawyers instant access to defined terms, cross-references, and precedent clauses without navigating away from the clause they are actively working on. The platform covers the full pre-execution contract lifecycle through four products: Vault for precedent clause surfacing, Draft for in-document navigation, Proof for automated proofreading, and the newly launched Cascade for tracking knock-on effects when a change in one clause affects others downstream. Drafting complex agreements is error-prone precisely because contracts are interconnected documents. A change to a defined term in clause 3 can silently break the meaning of clause 27. Cascade, launched in 2025, addresses this directly — it uses AI to map dependencies across the document and flags every provision that is materially affected when a lawyer edits a term or condition, reducing the risk of inconsistencies that manual review commonly misses. Definely raised $30 million in Series B funding in mid-2025, backed by Revaia, to accelerate global expansion. Its client base includes major law firms such as Dentons, A&O Shearman, and DLA Piper, as well as in-house legal teams at KPMG, Samsung, and BT Group. Pricing is not publicly listed and requires a sales conversation, which is standard for enterprise legal software at this tier. Definely is not designed for post-execution contract management tasks such as obligation tracking, deadline monitoring, or contract renewal workflows. Teams looking for a full contract lifecycle management platform with post-signature capabilities will need to pair it with a dedicated CLM tool.
Definely is an AI legal document drafting tool embedded in Microsoft Word that helps lawyers review, draft, and proofread complex contracts with greater speed and accuracy.
Definely is widely used by professionals, developers, marketers, and creators to enhance their daily work and improve efficiency.

Final Verdict
Compared to manual contract review, Definely's Cascade feature reduces the time lawyers spend identifying downstream clause impacts from multi-hour document scans to near-instant flagging — a meaningful difference on complex multi-party agreements. The trade-off is that pricing requires direct negotiation, which makes cost evaluation difficult for smaller firms without a procurement process.
