Overview

Shadow AIShadow AISince 2026-05

Shadow is an intelligent, privacy-first desktop AI assistant for macOS engineered to seamlessly observe your workflow, capture meeting context, and execute action items without intruding as an awkward meeting bot. Instead of inviting a bot to your Zoom or Google Meet calls, Shadow records audio and visual context locally from system hardware. By combining low-latency on-device speech transcription with multimodal screen intelligence, Shadow turns unstructured work conversations into clean summary memos, follow-up email drafts, Jira tickets, and calendar invites with a single click.

Shadow is built with privacy at its core: raw audio buffers and screen snapshots are processed locally using optimized Apple Silicon neural engine kernels. Only structured text context is routed to high-parameter LLMs for reasoning when explicitly requested by the user. Users can create and customize 'Skills'—reusable prompt automation blueprints that trigger automated actions like emailing meeting summaries to attendees, updating Notion databases, or logging customer feedback into product roadmaps.
