What is Claude AI?

Claude is an AI assistant — similar to ChatGPT — that you can talk to, ask questions, and give tasks. It can write articles, summarize long documents, help you code, answer complex questions, and much more.

Claude was created by Anthropic, an AI safety company founded in 2021 by former members of OpenAI, including Dario Amodei and Daniela Amodei. Anthropic’s main goal is to build AI that is safe, honest, and helpful.

The name “Claude” is inspired by Claude Shannon, the mathematician who invented information theory — the foundation of all modern digital communication.

What makes Anthropic different from other AI companies is their focus on AI safety. They developed a special training method called Constitutional AI — a technique that teaches Claude to be helpful, honest, and harmless by following a set of clear principles.

This is why Claude tends to be more careful, more honest, and less likely to make things up compared to other AI tools.
