Most desktop pets just sit there. Desk Gremlin works: click it for notes, reminders that reach your iPhone, focus timers, and screen recordings — plus an opt-in AI that answers questions, searches all your notes, looks at your screen, and calls your MCP tools. Privacy-first by design: everything lives in a local SQLite file you can inspect, zero telemetry, and AI can run fully on-device via Ollama. Free. macOS 14+.
