AI Contract Review & Due Diligence

About
Kira Systems is an AI contract analysis and due diligence platform that uses machine learning to automatically extract provisions, obligations, and key data points from contracts and legal documents at scale. Founded in 2012 and headquartered in Toronto, Canada, Kira was acquired by Litera in 2021, integrating its contract AI capabilities into Litera's broader legal document lifecycle platform. Kira built strong market recognition among large law firms and Big Four professional services organizations as one of the earliest and most accurate AI tools for contract review, earning a reputation for high precision extraction across complex transactional and compliance review projects.\n\nKira's technology is built around supervised machine learning models that law firms can train on their own document libraries to improve extraction accuracy for specific provision types and industries. This trainable AI approach differentiates Kira from systems that rely on pre-trained generic models, giving sophisticated users the ability to customize the tool for their specific practice areas and matter types. Common use cases include M&A due diligence, real estate portfolio review, lease abstraction, regulatory compliance mapping, and contract remediation projects.\n\nAs part of Litera's legal technology portfolio, Kira's AI capabilities are being integrated with Litera's document drafting, comparison, and management tools, creating a more comprehensive document lifecycle platform. Litera acquired several other legal technology companies including Workshare and Draftlogic alongside Kira, assembling a suite that covers the full spectrum from document drafting through contract analysis. Kira competes with Luminance, Evisort, and the contract AI capabilities of broader CLM platforms.
