Claude excels in a wide range of text-based tasks. Claude has been trained to ingest code, prose, and other natural language inputs, and provide text outputs in response.

Text generation

Claude is a highly performant, trustworthy, and intelligent AI platform built by Anthropic. Claude excels at tasks involving language, reasoning, analysis, coding, and more.

Overview

Welcome to Claude

Let&rsquo;s learn how to use the Anthropic API to build with Claude.

Initial setup

Claude is a family of [highly performant and intelligent AI models](/en/docs/about-claude/models) built by Anthropic. While Claude is powerful and extensible, it&rsquo;s also the most trustworthy and reliable AI available. It follows critical protocols, makes fewer mistakes, and is resistant to jailbreaks&mdash;allowing [enterprise customers](https://www.anthropic.com/customers) to build the safest AI-powered applications at scale.

Intro to Claude

Guides to common use cases
