Litera Kira

Kira Systems, acquired by Litera in 2021, is the long-standing AI contract review platform for BigLaw M&A teams and corporate legal departments. It was founded in 2011 in Toronto and its models are trained on millions of contracts, with 1,400+ pre-trained smart fields covering due diligence, general commercial, corporate organization, real estate, and compliance provisions. In July 2025 Litera launched the new Kira experience: Generative Smart Fields let users create custom extraction fields with a plain prompt in any language, Concept Search finds legal concepts from a single example, and grid-based analysis charts support chatting with documents and one-click client memos. It deploys on virtual data rooms and large contract repositories to summarize thousands of agreements in hours. Pricing is enterprise quote-based, reported at $50,000+ a year, with a setup fee and 4-8 week time-to-value. It is contract-focused by design — not an eDiscovery or litigation tool — and overkill for anyone reviewing fewer than a few hundred contracts a year.
