harvey vs cindy

harvey: Harvey is an autonomous sales agent that finds businesses, learns something specific about each, writes and sends cold email, and works replies toward a meeting. It runs locally in a 15-minute loop using a Claude Code or Codex subscription instead of a per-token API bill, and by default every email waits for approval.; 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.
