What is Claude and how it can help you be more productive
|AI
Claude isn't just Anthropic's answer to ChatGPT anymore. What launched in March 2023 as a safety-focused assistant from a lab founded by ex-OpenAI researchers has grown into a full agentic platform: a conversational assistant, a terminal-based coding agent, a desktop coworker that reaches into your files, and a shared teammate inside Slack. In this guide we explain what Claude is in 2026, how the Opus 5.5, Sonnet 5.5, and Fable 5.1 family fits together, what Claude Code, Cowork, and Claude Tag can do, what the plans cost, and how to use Claude well.
