Cline is the open-source coding agent that defined the in-editor agent category, with 5M+ installs across VS Code, JetBrains, and Cursor itself. Its Plan/Act modes separate thinking from doing — the agent proposes a plan you approve before it touches files or runs commands. Apache-2.0 licensed with full bring-your-own-key model freedom, MCP integration, and deployment options up to on-prem and air-gapped for enterprises.
Pi is a conversational AI assistant created by Inflection AI. It focuses on natural, empathetic dialogue and personal assistance rather than coding tasks. Pi excels at brainstorming, writing, learning, and general-purpose conversation with a warm, engaging personality.
