In their own words
Zuva
Zuva provides software for contract analysis, sell-side M&A diligence, bidder questions, and contract extraction. In its diligence service, lawyers use AI to review contracts for execution status and deal-relevant provisions, then prepare findings and outputs for disclosure schedules. Bidder Question Management imports question lists from Excel or Word, identifies similar questions, brings forward prior answers, and supports team coordination. Analyze classifies uploaded documents and runs built-in or custom extraction workflows; results can appear in its review interface or be exported to Excel or Word. Its REST API extracts contract provisions, classifies more than 225 document types, detects predominant language, and supports custom field training. The API can run as an Azure-hosted service in a US or EU region, or be self-hosted on Azure or AWS. Analyze can be tried on five documents without a credit card, and the API free tier has daily limits. API and Analyze pay-as-you-go plans each require a $5,000 minimum commitment.
