Definely is a high-growth, UK-based LegalTech company founded by former Magic Circle lawyers. Its platform offers a suite of five integrated AI-powered tools that operate as a Microsoft Word add-in, designed to radically improve the efficiency and accuracy of legal document work for lawyers and in-house counsel.
The Definely AI Suite: Key Features
Definely's core strength is its unified suite of tools, ensuring lawyers can manage the entire pre-execution contract lifecycle without leaving MS Word.
1. Definely Draft: For Active Drafting & Review
The flagship product, designed to eliminate context-switching. With a double-click, lawyers can instantly view any defined term or cross-reference in a side panel, maintaining focus. It also allows split-screen editing of clauses, with changes automatically updated throughout the document and tracked via MS Word's native "Track Changes".
- Instantly access definitions and clauses without scrolling
- Edit referenced text in a split-screen view
- Navigate seamlessly across multiple related legal documents
- Generate reports on defined, undefined, and unused terms
2. Definely Proof: AI-Powered Quality Control
An AI proofreading engine that goes beyond spell-check to catch legal-specific errors. It automates hundreds of checks to help produce error-free contracts and mitigate risk.
- Flags inconsistencies in definitions, numbering, and cross-references
- Identifies and helps remove leftover drafting notes (e.g., bracketed text)
- Corrects formatting issues related to punctuation, spacing, and styles
- Can enforce a firm's specific "House Style" guide
3. Definely Vault: Leverage Your Firm's Knowledge
Transforms a firm's document repository into a searchable knowledge base. Using semantic search, it surfaces relevant precedent clauses and definitions from past work directly within Word, accelerating the drafting of new documents.
- AI-powered search for internal precedents
- Connects to your existing Document Management System (DMS)
- Insert relevant clauses directly into your active document
- Maintain institutional knowledge and consistency
4. Definely PDF: Unlock Static Documents
Extends the core navigation functionality to non-editable PDF files. Using advanced Optical Character Recognition (OCR), it makes scanned or digital PDFs as easy to review as Word documents, a crucial tool for due diligence and reviewing legacy contracts.
- Applies one-click definition and reference checking to PDFs
- Analyzes all terms and references within the PDF
- Ideal for reviewing opposing counsel's drafts or executed agreements
- Simplifies due diligence processes
5. Definely Enhance: The Agentic AI Co-pilot
The newest offering, acting as a conversational AI layer over the entire suite. It uses a team of specialized AI agents to handle complex, multi-step tasks based on natural language commands, from summarising issues to drafting new clauses based on precedents.
- Conversational interface for complex queries
- Multi-agent AI system for more accurate and reliable results
- Can take direct action in the document with user approval
- Adapts to firm-specific terminology and preferences

Ease of Use & Implementation
Definely's greatest strength is its seamless integration into the existing legal workflow. As an MS Word add-in, it requires minimal training and doesn't force lawyers to adopt a new, standalone platform. This "light" integration model, which works on top of documents opened from any DMS, significantly reduces IT overhead and speeds up adoption within firms.
For UK legal teams, the implementation process typically involves:
- Initial consultation to determine which tools from the suite are needed
- IT deployment of the Word add-in (typically via Microsoft AppSource)
- Configuration of firm-specific settings and preferences
- Integration with existing document management systems
- Training sessions for legal professionals (typically 1-2 hours)
Pricing & Plans (UK Focus)
Pricing for Definely is quote-based and tailored to the size and needs of the law firm or corporate legal department. The modular nature of the suite allows firms to start with one or two products and expand over time.
- Custom Subscriptions: Plans are based on the number of users and the specific products required from the suite.
- Enterprise Solutions: Tailored packages for large law firms and corporations like Deloitte, Slaughter and May, and A&O Shearman.
- Land and Expand Model: Firms can pilot a single tool like `Proof` or `Draft` before committing to the full suite.

UK legal professionals have shared their experiences with Definely:
Jonathan P., Partner, Corporate Law
"As someone who regularly works with complex M&A agreements, Definely has been transformative. The ability to instantly access definitions without scrolling through a 100-page document has saved me countless hours. The Proof tool has caught several embarrassing errors that would have otherwise made it to the client. Well worth the investment."
Sophia M., In-House Counsel, Financial Services
"Our legal team has been using Definely for about 8 months now. The Draft and Proof tools are excellent and have significantly improved our efficiency. The only reason for 4 stars instead of 5 is that the implementation required more IT involvement than expected, and the pricing is definitely at the premium end. That said, the time savings have more than justified the cost."
