Claude is Anthropic's AI assistant — widely regarded as the best AI for long-form writing, nuanced analysis and tasks requiring careful reasoning. Built by Anthropic with a focus on safety and helpfulness, Claude produces the most natural-sounding AI content available and is particularly strong at understanding context, following complex instructions and maintaining consistency across long documents.
Claude's standout capabilities include its massive context window (up to 200,000 tokens on Claude Pro — equivalent to a full book), its ability to analyse and summarise long documents, its nuanced writing that avoids the robotic tone common in other AI tools, and its coding assistance that excels at understanding and explaining complex codebases. For professionals who need AI that sounds genuinely human, Claude consistently outperforms alternatives.
Claude is available through claude.ai as a standalone product and through the Anthropic API for developers. The free tier provides access to Claude with usage limits; Claude Pro at $20/month gives priority access, higher usage limits and access to the latest models including Claude 3.5 Sonnet and Claude 3 Opus.
