# Branching Reasoning AI Chat Input

> Branching Reasoning AI Chat Input for React and Tailwind CSS (shadcn/ui) compares approaches. It is built to make a chosen approach clear. Fanned cards, score bars, a 520ms merge, streaming text, and expandable alternatives support controlled state and controlled or local drafts. Includes keyboard access, reduced motion, and light/dark themes. Use it for AI chat, assistants, or SaaS. The included demo simulates sample scores and an answer; the component makes no requests. Requires React and lucide-react, with no animation library.
