Kira Systems is an AI contract analysis platform acquired by Litera in 2022, used by law firms, Big Four accounting firms, and corporate legal teams for large-scale contract review in due diligence, M&A transactions, lease abstraction, and regulatory compliance projects.
Kira's ML models extract specific contract provisions — representations and warranties, change of control clauses, assignment restrictions, indemnification, limitation of liability, termination rights — from contracts across formats, layouts, and writing styles without requiring fixed templates.
The Kira training approach allows users to train the system on their firm's own provisions — labelling examples of how a specific provision type appears in their contract corpus to improve extraction accuracy for firm-specific review patterns. This custom training produces higher accuracy for specialised review types than general models.
Batch contract review processes thousands of contracts simultaneously — during M&A due diligence where review teams may need to review 5,000+ contracts in weeks, Kira extracts key provisions across all contracts in hours rather than requiring paralegal reading of each document.
Integration with Litera's broader legal document technology suite (Litera is the legal technology holding company) provides connectivity with contract lifecycle management, document drafting, and proofreading tools used by law firms.
Kira Systems AI runs as document analysis llm software built around text and document workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api.
