Kira Systems leverages multi-layer AI to automatically extract, analyze, and review contract provisions across thousands of legal documents, delivering 90%+ accuracy for M&A due diligence, compliance audits, and large-scale contract review.
AI-powered contract analysis platform that automates legal document review and accelerates due diligence processes for law firms and corporate legal teams
Kira Systems stands as one of the most established and trusted AI-powered contract intelligence platforms in the legal technology market. Now part of the Litera ecosystem, Kira serves 70% of the top 50 global law firms, four of the five UK Magic Circle firms, three of Canada's Seven Sisters firms, and three of the Big Four accounting firms.\n\nAt its core, Kira employs a multi-layer AI architecture that combines battle-tested proprietary machine learning models with optional Generative AI capabilities. The proprietary models draw on over a decade of AI innovation and more than 45,000 hours of lawyer-contributed training data, resulting in 90%+ extraction accuracy across 1,400+ pre-trained smart fields covering common contract provisions. Unlike pure GenAI solutions that can hallucinate or fabricate clause language, Kira's hybrid approach cross-validates results between ML and generative layers to minimize errors in high-stakes legal work.\n\nThe platform addresses the full lifecycle of contract review and due diligence. Teams begin by importing documents in bulk from virtual data rooms, cloud storage, or internal repositories, with built-in deduplication ensuring clean datasets. Kira automatically classifies, tags, groups, and assigns documents while detecting languages and jurisdictions. Reviewers then work through structured review workflows using the document viewer and Analysis Grid, applying smart fields to extract key provisions, flagging issues, generating comparisons and redlines, and exporting results to Word, Excel, or PDF.\n\nGenerative Smart Fields represent a significant advancement in Kira's capabilities, allowing users to create custom extraction fields by simply typing natural language questions. Unlike traditional ML-based fields that require labeled training data, Generative Smart Fields work immediately in any language and can be previewed and refined before deployment. Concept Search complements this by enabling users to find conceptually similar language across all project documents using a single example phrase, without any GenAI dependency.\n\nKira's governance model sets it apart from competitors like Harvey AI and Luminance. Organizations can toggle GenAI features on or off at the project level, meeting strict client or regulatory requirements without losing access to the platform's non-generative capabilities. Data is never used for model training, and Kira maintains SOC 2 Type II certification with GDPR, DORA, and NIS2 alignment. Data residency options span the US, Canada, Europe, and Asia Pacific.\n\nThe bundled Lito AI Legal Agent extends Kira's value beyond the platform itself. Included at no additional cost for Kira customers, Lito operates directly in Microsoft Word, Outlook, and web browsers. It handles everyday legal tasks like NDA playbook checks, structured reviews, risk analysis, and agentic redlines without requiring users to switch applications.\n\nCompared to competitors, Kira differentiates on accuracy and enterprise readiness. Harvey AI focuses more on general legal question-answering powered by large language models but lacks Kira's decade of contract-specific ML training. Luminance offers similar contract analysis capabilities but with a different AI architecture. Ironclad concentrates on contract lifecycle management rather than deep extraction and review. LinkSquares targets mid-market legal teams with analytics-focused features. Evisort provides AI-powered contract management but with less emphasis on high-volume transactional due diligence.\n\nKira integrates with HighQ and Intralinks for data room connectivity and offers an Open API for custom integrations with existing document management systems. The platform also connects with Litera Transact, enabling users to view contract review progress directly in the Transact dashboard and reducing context switching during complex transactions.\n\nPricing follows an enterprise subscription model with custom quotes based on organizational size, document volume, and feature requirements. While Kira does not publish pricing publicly, the platform targets law firms and corporate legal departments handling significant contract volumes where the ROI from time savings and risk reduction justifies the investment. Firms typically report up to 50% reduction in contract review time after deployment.\n\nFor legal teams evaluating AI contract analysis solutions, Kira offers a compelling combination of proven accuracy, flexible governance, enterprise-grade security, and deep integration within the broader Litera legal technology ecosystem. The platform continues to evolve with regular updates emphasizing collaboration features, expanded template libraries, and improvements in speed and user experience.

Kira Systems excels at large-scale contract analysis with proven accuracy and efficiency for major legal transactions. Users praise its ability to handle complex due diligence projects that would take months manually, though note the significant upfront training investment required.
Kira combines proprietary machine learning models trained on 45,000+ lawyer hours with optional Generative AI to extract contract provisions with 90%+ accuracy. The hybrid approach reduces hallucinations while maintaining flexibility for custom extraction needs.
Use Case:
A law firm conducting M&A due diligence extracts change-of-control clauses, termination provisions, and indemnification terms from 5,000 contracts in days instead of weeks.
Create custom extraction fields by typing natural language questions without labeled training data. Generative Smart Fields work in any language and can be previewed, refined, and published instantly across document sets.
Use Case:
A corporate legal team creates a custom field asking 'Does the contract contain a most-favored-nation clause?' and applies it across an entire portfolio without ML training.
Provide an example phrase or clause and Kira instantly finds conceptually similar language across all project documents. Works without training, prompting, or GenAI, making it available even in restricted environments.
Use Case:
A compliance officer searches for non-compete language across 10,000 employment agreements by pasting a single example clause, finding all variations in seconds.
Toggle Generative AI features on or off at the project level to meet firm or client requirements. Non-GenAI features remain fully functional, ensuring teams maintain compliance without sacrificing productivity.
Use Case:
A law firm working on a sensitive government contract disables GenAI for that project while keeping it enabled for commercial M&A work.
Bundled at no extra cost, Lito operates as an AI legal agent embedded in Microsoft Word, Outlook, and web browsers. Lito automates structured reviews, NDA playbook checks, grid-based multi-document analysis, and agentic redlines.
Use Case:
An associate reviews an NDA directly in Word using Lito, which highlights deviations from the firm playbook and suggests redlines without switching to a separate platform.
Custom quote; typically high five figures annually (~$50,000–$99,000/year) based on document volume and user count
Custom quote; typically six figures annually ($100,000–$500,000+/year) with volume discounts for large deployments
