cindy vs Observer

cindy: Cindy is an open-source AI agent that brings several harnesses (Claude Code and Codex first), models and tools into one agent running locally on your machine with your real files and logged-in apps. Models and harnesses can switch mid-task while memory, skills and tools stay continuous, and it can drive your browser, computer and phone and take work from IM and schedules.; Observer: Observer lets you build micro-agents that watch your screen, camera, microphone or clipboard and run a small local model on a loop. When the model spots a condition, JavaScript tool code sends a notification (email, Discord, Telegram, SMS, WhatsApp), records a clip or writes to memory.
