Concord Horizon is a next generation contract management platform rebuilt for the AI era, applying ten years of Concord expertise to a modern, AI native architecture.
Horizon gives teams a cleaner, faster interface with light and dark mode, collapsible navigation, custom and pinnable columns, advanced filtering, and consistent tables across every module so users can work in full screen focus when they need it.
AI Copilot lets you ask natural language questions about any contract, summarize or extract key points, and generate quick insights or reports, while AI Search combines lexical and semantic search to find meaning rather than just keywords and perform multi actions on results.
With MCP you can bring contract insights into tools like ChatGPT or Claude to generate summaries or tables from your portfolio and automate contract monitoring, all backed by a zero data retention policy with AI partners so customer data is never used to train AI models.
