Shadow: AI Companion with Multi-Agent Workflow

Shadow is a quiet AI companion for web, Android, iOS and desktop. It brings ChatGPT, Gemini, Grok, DeepSeek and OpenRouter into one calm interface, so you stop switching between apps, tabs and subscriptions. What makes it different: an expressive animated character that reacts as you talk, and a "Shadow" auto-router that picks the best connected model for each prompt. You can bring your own API keys (stored encrypted) or sign in once with OpenRouter. It also has projects with files, saved conversations, and an AI Office where agents hand work to each other, all from one codebase.
