Claude

Claude is an advanced AI assistant by Anthropic that serves as an intellectual partner for solo entrepreneurs managing every aspect of their business. Built on Constitutional AI principles, Claude is designed to be helpful, harmless, and honest—delivering thoughtful, nuanced responses that go far beyond surface-level answers. The platform excels across an astonishing range of tasks: code generation and debugging in any programming language, complex data analysis and insights, business strategy and planning, content writing and editing, research and learning, customer support responses, and technical documentation. Claude Opus 4.5, released in November 2025 and described as the best model for coding and agents, gives solo developers access to enterprise-grade AI capabilities at consumer pricing. What distinguishes Claude is its extraordinary 200,000+ token context window—you can upload entire codebases, books, financial documents, or research papers, and Claude will analyze them with full understanding. The free tier provides daily usage limits perfect for exploring what's possible, while the Pro plan at just $20/month (or $17/month annually) removes those limits and adds advanced features like web search for research and computer use for workflow automation. For API users and enterprises, Claude's transparent token-based pricing and three model tiers (Haiku for speed, Sonnet for balance, Opus for power) provide cost-effective scaling. With a proven track record in AI safety and continuous improvements to reasoning capabilities, Claude has become the preferred choice for builders, writers, analysts, and entrepreneurs who demand both reliability and cutting-edge AI capabilities.
