Detailed Review
Definely does less than a full legal AI suite and says so. Its slogan is that the maker cannot be the checker: it is meant to review a draft, whether a person or an AI wrote it, and to keep the lawyer in charge.
The terms of use are issued by Defeyene Legal Solutions Limited trading as Definely, and Companies House lists the company at 2 Leman Street in London, incorporated in April 2017. The terms are governed by English law.
Defined Terms Without Scrolling
A clause on page 12 can hang on a definition on page 80. Definely shows that definition beside the clause, and flags a term defined twice, a broken cross-reference or a stray capital letter.
Suggest, Then Decide
Findings are sourced and anything you accept becomes a tracked change, reviewable word by word. Comparison runs the draft against your standard form and the deal documents, and a report turns markup into an issues list and a gaps list.
Precedent and MCP
The precedent search connects to a firm's document management system and inserts a clause with its formatting and definitions. Through MCP the same rules-based review works inside Claude, ChatGPT or an in-house AI tool.
Limitations to Consider
It reviews and does not research: there is no case law database or general legal assistant, so firms usually pair it with a research tool such as Legora. It lives in Microsoft Word, which suits transactional work and not litigation bundles. Pricing and hosting are not published on the pages we could open. A UK company, so it sits outside the EU, though inside the list EP accepts.
Who Should Use Definely
Corporate and finance lawyers who spend their days in long agreements with heavy cross-referencing and want a second pair of eyes that does not rewrite their text.
