What is Claude?

Claude is Anthropic's flagship AI assistant, and it occupies a distinct position in the AI landscape. While ChatGPT is the default recommendation for general use, Claude has built a reputation among researchers, writers, legal professionals, and anyone who regularly works with long or complex documents. The difference is not just context length, though Claude's ability to hold and reason across very large documents is a genuine practical advantage. It is also about the character of the output: Claude tends to produce more careful, measured writing that holds up better under scrutiny.

Anthropic was founded in 2021 by former OpenAI researchers, and the company's focus on AI safety is reflected in how Claude behaves. It is notably less likely to produce confident nonsense on topics it does not know well, more likely to acknowledge uncertainty, and more careful about refusing requests that edge toward harm. For some users this feels appropriate and trustworthy. For others, it can occasionally feel overly cautious.

The practical use cases where Claude stands out include reading and summarising long reports, contracts, and research papers; drafting long-form content with a consistent and readable voice; analytical tasks that require keeping track of detail across large inputs; and coding assistance, where it performs competitively with leading alternatives. Its extended context window means you can paste entire codebases, research papers, or lengthy documents and ask questions that reference specific sections without the assistant losing track.

The Claude Pro plan, at $20 per month, is comparable in price to ChatGPT Plus and gives access to the Sonnet and Opus model tiers with meaningfully higher usage limits than the free plan. The Team plan adds shared access and collaboration features suitable for small businesses. Enterprise pricing is available for organisations with stricter data handling, compliance, and volume requirements.

On integrations, Claude's ecosystem is narrower than ChatGPT's. There is an API that developers use widely, and Claude powers many third-party products, but the consumer-facing integration story is more limited than what OpenAI has built with its plugin marketplace and Microsoft partnership. If you rely heavily on a specific third-party workflow and need guaranteed native support, it is worth checking whether Claude connects to it directly.

Privacy considerations are worth reading carefully before using Claude with sensitive information. The free plan's data handling differs from enterprise arrangements, and Anthropic publishes documentation on what is and is not used for model training. For organisations with specific compliance requirements, the enterprise tier includes contractual protections.

Who should use Claude? It is genuinely well-suited to writers who want a thoughtful collaborator rather than a fast output machine, researchers who regularly feed it long material, lawyers and analysts who need to extract meaning from dense documents, and developers who want strong coding support combined with better-than-average explanation of what the code is doing. People who need a wide integration ecosystem, voice input, or image generation may find ChatGPT or Gemini more practical for their workflows.

Claude is not trying to do everything. That focused approach is both its strength and its limitation, depending on what you need.

How Claude works

Claude runs as llm assistant software built around text and code workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, ios, and android, with API access for teams that want to embed it into their own products.
