What is Claude?

Claude (currently the Claude 4 family — Sonnet 4.6 and Opus 4.8, with Haiku 4.5 for lighter tasks) is Anthropic's answer to ChatGPT, and in many ways it punches above its weight. The thing most users notice first is the writing quality — Claude has a more natural, less formulaic tone than many other AI assistants. Since March 2026 its flagship models also run a 1-million-token context window at standard pricing, meaning you can feed it entire books, legal contracts, or long reports for analysis. The free plan is genuinely generous. Claude Pro at $20/month ($17/month billed annually) unlocks Claude Code, Claude Design, unlimited projects, and higher usage limits, with a Max plan from $100/month for the heaviest users. It integrates with tools like Slack, and its 'Projects' feature lets you build persistent workflows.
