What is Claude AI?
Claude’s Core Design Principles:

Claude is a conversational AI assistant built on large language models (LLM), developed by Anthropic. Users interact with it through text, either by asking questions or giving instructions. The system processes inputs to generate human-like responses. Anthropic designed Claude to be helpful, harmless, and honest, guided by these three principles.

The interface is clean and simple; users type messages and receive responses without complicated setups. The free tier grants access to Claude with some usage limits, while paid plans offer more features and higher usage caps.
Why Claude Exists and Its Purpose
Anthropic developed Claude AI to address safety concerns in AI development. Founders believed existing AI models needed better alignment with human values, introducing constitutional AI as a method where the model learns from principles rather than just human feedback.
