I tried Expo's new Exact with Convex

A new pre-alpha framework from Expo called Exact is demonstrated by building a real-time, cross-platform chat application. The app runs natively on the web, Mac, and mobile from a single UI codebase, all powered by a Convex backend for data synchronization. Exact uses its own typed language called Contract, which resembles Python but is designed for building UIs similar to React, and allows for near-instantaneous code updates across all devices. A key feature highlighted is its suitability for "agentic development," as it allows AI agents to control the application clock, making testing and automation more reliable by avoiding race conditions with animations.
