Anthropic's AI assistant, known for safety and helpfulness, with particular strength in long-form text and analysis.

Product preview

Overview

Claude is Anthropic's AI assistant, designed from the ground up around helpfulness, honesty and harmlessness. It is widely regarded as one of the best models for long-form text: it handles very large documents and codebases, follows nuanced instructions closely, and produces prose that reads naturally rather than mechanically.

The product line spans a free chat app, a Pro plan with higher limits and project features, and developer tooling such as Claude Code for terminal-based engineering. Teams lean on it for document review, technical writing and complex refactors where care and precision matter more than flash.
