Claude
Anthropic's safety-focused AI assistant. Exceptional at long-form writing, analysis, coding, and nuanced reasoning.
What is Claude?
Claude is Anthropic's AI assistant, known for its exceptional ability to handle long documents, nuanced analysis, and complex coding tasks. Built on Anthropic's Constitutional AI approach, Claude is designed to be helpful, harmless, and honest. The latest Claude 4 Opus model is one of the most capable AI models available, excelling at reasoning, coding, and extended context understanding.
What Sets Claude Apart
Claude's standout feature is its massive 200K token context window — it can process entire books, codebases, or research papers in a single conversation. While most AI assistants struggle with documents longer than a few pages, Claude can analyze a 500-page PDF and answer detailed questions about specific sections. Its coding abilities rival dedicated coding assistants, and its writing style is notably more natural and less "AI-sounding" than competitors.
Key Capabilities
- 200K Context Window: Process entire books, legal contracts, or full codebases in one conversation
- Advanced Coding: Write, debug, and refactor code with deep understanding of software architecture
- Document Analysis: Upload PDFs, CSVs, images, and get detailed analysis and summaries
- Artifacts: Claude creates interactive code previews, documents, and visualizations right in the chat
- Projects: Organize conversations with persistent context and shared knowledge bases
- Computer Use: Claude can interact with your desktop to complete tasks autonomously
