Kira Systems (a Litera product) is an AI contract-review and due diligence platform that extracts key provisions, answers deal-critical questions in plain language, and reports findings across thousands of contracts with source-linked, legal-grade accuracy. It's purpose-built for M&A, real estate, and banking/finance deal teams at law firms and corporate legal departments handling high-volume review. Its differentiator is 1,400+ pre-built lawyer-trained smart fields paired with both predictive and generative AI, with every answer cited back to the source contract.

TaxGPT is an AI tax co-pilot built for CPAs, accountants, and tax firms (from solo practitioners to enterprise) that automates tax research, drafts client-ready memos and IRS correspondence, and analyzes returns and tax documents, all with cited answers pulled from the IRC, Treasury Regulations, court cases, and IRS guidance. It goes beyond a chatbot with client-memory profiles, AI 'Cowork' agents that run firm workflows inside existing software, and Agent Andrew, an audit/review tool that flags return errors and missed tax savings. Its main differentiator is built-in hallucination control with every answer cited to authoritative sources, positioned as faster and more accurate than legacy tools like Thomson Reuters and CCH.
