Kira Systems is an AI contract-analysis platform founded in 2011 in Toronto, Canada, that built its reputation automating due-diligence contract review for law firms and corporate legal departments. Litera acquired Kira Systems in 2021 and continues to operate and develop it as the "Kira" product inside Litera's broader legal-technology suite.
Kira combines predictive AI models trained by Litera's in-house Legal Knowledge Engineering team on over a million contracts with newer generative-AI tools, aiming for what the company reports as 90%+ extraction accuracy across use cases like M&A due diligence, real estate, and finance review. A 2026 update added Grid Chat for natural-language querying across review results. Litera reports Kira in use at roughly 70 of the top 100 global law firms and over 80% of the top 25 M&A firms.
Kira fits corporate legal departments and law firms running high-volume contract review who need governance controls and audit trails, rather than solo practitioners. Pricing is enterprise-only and quoted through a sales conversation; firms already on other Litera products (Transact, Microsystems, Foundation) get more favorable bundle pricing than a standalone Kira purchase.
