Claude

Claude is built by Anthropic, a company founded by former OpenAI researchers with a focus on AI safety. What started as a safety-first research project has produced an assistant that many professionals now prefer over ChatGPT for serious work — particularly writing, analysis, and complex reasoning tasks.

What it does

Claude is a conversational AI assistant that excels at understanding and generating text. It handles the same broad range of tasks as other leading assistants — writing, coding, analysis, summarisation, brainstorming — but with a notably different personality. Claude tends to be more measured, more willing to acknowledge uncertainty, and more attentive to nuance. It reads more like a thoughtful colleague than a eager-to-please chatbot.

How it works in practice

Claude is available through a web interface at claude.ai and via API. The free tier provides access to Claude Sonnet, which is highly capable for most tasks. The Pro plan ($20/month) unlocks Claude Opus — the most powerful model — along with higher usage limits and priority access during peak times. Projects let you organise conversations by topic and attach reference documents that persist across chats.

The standout technical feature is Claude's industry-leading context window. Claude can process up to 1,000,000 tokens — roughly equivalent to several books or an entire codebase — in a single conversation. This means you can upload entire documents, codebases, or research papers and have a meaningful conversation about them without the AI losing track of earlier content.

Where it excels

Claude is widely regarded as the best AI for writing. Its output tends to be more natural, less formulaic, and better at maintaining a consistent voice across long documents. For professionals who need AI to draft reports, articles, proposals, or communications that actually sound human, Claude is the top choice.

It is also exceptionally strong at analysis. Upload a contract, a financial report, or a research paper, and Claude will identify key points, flag potential issues, and answer detailed questions with a level of care that sets it apart. The long context window makes this practical in a way that shorter-context models cannot match.

Where it falls short

Claude does not generate images and has a more limited integration ecosystem compared to ChatGPT. If you need an all-in-one tool that handles text, images, code execution, and connects to dozens of third-party services, ChatGPT or Gemini may be more practical. Claude also lacks a native plugin or GPT-like marketplace, though its API is widely supported by automation platforms.

Claude can also be overly cautious. Its safety training occasionally causes it to decline requests that are perfectly reasonable, particularly around topics it flags as sensitive. This is improving with each model update but remains noticeable.

The business case

For knowledge workers, researchers, writers, and professionals who value quality of output over breadth of features, Claude Pro is excellent value. The Team plan adds collaboration features, and the Enterprise tier offers enhanced security, SSO, and custom deployment options.
