Description

Shadow is an ambient AI companion that lives on your screen as an animated character. It passively listens to your meetings, detects action items in real-time, and autonomously executes them sending Slack messages, generating infographics, building and deploying landing pages, creating audio jingles, all without being asked. No trigger words. No interruptions. You talk naturally, and Shadow just acts.

An ambient AI companion with a desktop pet interface, built for the **Zero to Agent Hack** (DeepMind x Vercel).

Shadow is a pixel-art cat that lives on your screen, listens via voice or text, and orchestrates a suite of AI agents to take real actions on your behalf — send Slack messages, generate infographics, build and deploy landing pages, and create audio content.
