Nudge-Claude-Code-Plugin

Build products people can't put down

Nudge is a Claude Code plugin that brings behavioral design and color psychology expertise to your workflow. It gives you the same psychological frameworks used by product teams at Meta, Google, Duolingo, Netflix, and Spotify — plus a research-grade color system — without the $250-500/hr consulting fee.

Whether you're auditing an existing app for engagement patterns, designing onboarding from scratch, writing button copy that actually converts, or building a brand color system from the ground up — Nudge has a specialist agent for that.
