Claude
Claude is Anthropic's family of AI assistants known for long context windows, nuanced reasoning and strong enterprise adoption.
Claude is Anthropic's AI assistant family, founded in 2021 by former OpenAI researchers. The family has three tiers (Haiku, Sonnet, Opus) distinguished by their large context windows (up to 1 million tokens), consistent tone of voice and strong analytical capability. For GEO, Claude is less visible than ChatGPT because it has no public search engine — users mainly chat via claude.ai or the API. That said, Claude fetches web sources via its web search tool and via partner integrations.
Example
A legal advisor works with Claude and asks: 'Compare GDPR obligations for Dutch fintechs versus German ones.' Claude reads multiple web sources, produces a tabular comparison, and cites URLs. Being found for that context brings authority in a niche.
Frequently asked questions
What sets Claude apart from ChatGPT?
Three things. Much larger context window (handles full books or large codebases in one conversation). A more nuanced writing style with less AI-jargon. Stronger 'constitutional AI' principles — Claude asks clarifying questions more often and is less likely to confidently state incorrect facts.
Does Claude use web search?
Yes, once the web-search tool is enabled (available on claude.ai and via the API). Without it, Claude works purely from its training data up to the cut-off.
