Definely
What is Definely?
Definely is a LegalTech platform built for lawyers who review complex contracts in Microsoft Word. The company offers a suite of Word add-ins that help legal teams navigate definitions, proof documents, track ripple effects from edits, search precedents, and ask questions about contract language without leaving the document.
The product grew out of a real accessibility challenge. Co-founder Feargus MacDaeid, a former Magic Circle lawyer who is registered blind, could not move through long contracts the way sighted colleagues could. Definely started as a way to reach defined terms and cross-references from inside a clause, then expanded into broader contract review workflows.
Law firms and in-house legal teams use Definely to cut review time, keep formatting consistent, and reduce risk in negotiations. The company reports more than 150 customers worldwide, including firms such as Dentons, A&O Shearman, and DLA Piper plus in-house teams at KPMG, Samsung, and BT Group.
Docsum
What is Docsum?
Docsum reviews and redlines contracts using configurable playbooks built for in-house legal teams. Upload an agreement or work directly in Microsoft Word through the native add-in, and Docsum flags risks, missing clauses, and deviations from your standards. It applies tracked changes and negotiation comments inside Word rather than in a separate editor.
Most contract AI tools review in isolation from where lawyers actually work. Docsum integrates into Microsoft Word and email workflows, pulling precedent from its contract repository so each redline reflects your prior agreements. Email agents automate clause suggestions during negotiation, and the platform syncs with DocuSign, Google Drive, Gmail, and Outlook.
Legal, sales, and finance teams use Docsum to cut review time from hours to minutes. Y Combinator-backed Docsum claims 3x faster negotiation cycles. Contract data is encrypted and never used to train AI models. A free trial is available through the Microsoft Marketplace Word add-in.
