Overview
Companion is a next-generation AI agent designed to function as a persistent 'OS layer' rather than a standalone application. Built on a hybrid architecture that combines local Computer Vision (CV) with cloud-based LLM reasoning (utilizing GPT-4o and Claude 3.5 Sonnet equivalents in 2026), Companion maintains a real-time semantic index of everything the user sees on their screen. This allows it to bridge the gap between siloed applications, executing cross-platform workflows that traditionally require manual intervention. Its technical core utilizes a proprietary 'Action-Model' that translates natural language intents into precise mouse clicks, keystrokes, and API calls. Positioned for the 2026 market, Companion prioritizes 'Local-First' privacy, where sensitive screen data is processed on-device, and only anonymized metadata is sent to the cloud for complex reasoning. It represents the shift from generative AI to 'agentic AI,' moving beyond text generation into proactive task execution, lifecycle management, and complex information synthesis across a user's entire digital ecosystem.
