Claude
FreemiumAnthropic's safe and thoughtful AI assistant for long-form writing, analysis, and complex reasoning.
What is Claude?
Claude is Anthropic's AI assistant, known for long-context work, careful writing and strong coding performance. Its model family spans Haiku for high-volume tasks, Sonnet as the balanced default, and Opus for complex agentic and enterprise workloads, with the newer models carrying a one-million-token context window at standard rates. Beyond chat it powers Claude Code for developers and integrates with desktop and mobile apps. The subscription ladder is simpler than most: Free with no expiry, Pro at $20 a month or about $17 billed annually, Max at $100 or $200 for substantially higher limits, plus Team and Enterprise seats. The mechanic to understand is the rolling usage window: rather than a fixed daily cap, limits reset on a session basis every few hours, and long PDFs or image attachments consume the allowance faster than short text exchanges. API access is billed separately per token.
