Diligen is a cloud-based contract analysis and management platform built for law firms, corporate legal departments, and legal service providers. It uses machine learning and natural language processing to identify key provisions and extract clauses across large document sets. The tool targets teams that regularly review high volumes of contracts under time pressure.
The platform addresses the repetitive, manual nature of contract review. Legal teams often face large contract backlogs and tight deadlines, which raises the risk of human error. Diligen automates extraction of critical provisions and generates instant summaries, reducing manual effort without requiring a proportional increase in headcount.
Users upload or import documents, and hundreds of pre-trained clause models scan the text to surface key provisions. Teams can filter and sort document sets by contract type, governing law, or specific clauses. Project management tools let managers assign contracts, track review progress, and edit auto-generated summaries before exporting them as Word or Excel files.
A notable differentiator is the ability to train custom clause models for niche practice areas. Diligen also connects to existing document management systems, including Box, NetDocuments, and Clio, so teams can process files without changing their established workflows.
Pricing
Diligen offers three paid tiers: Essential at $350 per month, Professional at $500 per month, and Enterprise at $1,600 per month.
