Concord is an objective tool for finding common ground in a debate. You paste a two-sided conversation and Concord uses Claude to map it: it extracts each side's core points, identifies where the two sides genuinely agree, and pairs up where they directly conflict — rendered as a visual "position map." It's built as a reusable synthesis engine: the demo runs on everyday debates, but the same pipeline applies to civic input, policy consultation, and stakeholder analysis. It also includes an epistemically-honest fact-check endpoint that refuses to fabricate sources. Built with a FastAPI backend powered by Claude Opus 4.8 and a web frontend.
