What is Claude AI?

Claude AI is Anthropic’s AI model – developed with a focus on safety, helpfulness, and honesty.

What can Claude do?

Claude understands and generates text at the highest level: analysis of complex documents, writing code, creative texts, strategic advice. Claude works with images, PDFs, and structured data and solves multi-step tasks independently.

What sets Claude apart?

Anthropic pursues the Constitutional AI approach – a training method in which the model gives helpful and safe answers based on defined principles. Claude is less prone to hallucinations and more transparent about its limits.
