The Complete Guide to Desktop AI Assistants in 2026
How does a desktop assistant work?
Jarvis (getjarvis.eu) is a desktop AI assistant that runs across macOS, Windows, and Linux. It opens from a floating-bar hotkey, can read your screen on demand, and connects to 30+ apps. Persistent memory and routing across Anthropic, OpenAI, and Google models support work across windows. The desktop pattern beats web-only AI in three ways: lower invocation cost (hotkey vs new tab), screen context (the assistant sees what you see), and app integration (read/write to Gmail, Slack, Notion, GitHub via OAuth). This guide covers per-tool capability comparisons, setup workflows, privacy considerations, and the per-job recommendations. Scroll down for the full guide with screenshots and the decision tree.
