について Claude (claude.ai)

Claude is Anthropic's conversational AI assistant, accessible at claude.ai and powered by the Claude Sonnet, Opus, and Haiku model family. It is widely regarded for its nuanced writing, strong reasoning on complex problems, and an exceptionally large context window (200K tokens) that lets it process entire books or large codebases in a single conversation. Claude supports file analysis, image understanding, web search, and "Artifacts" — interactive, editable outputs like code, documents, and diagrams. Its emphasis on helpfulness and honesty has made it a favorite among writers, researchers, and developers.

よくある質問

Is Claude free?

Claude offers a free tier with daily message limits. Claude Pro ($20/month) raises limits, unlocks Claude Opus, and gives priority access during peak times.

How much text can Claude process at once?

Claude supports up to a 200,000-token context window — roughly a 500-page book — making it one of the best tools for analyzing long documents or large codebases in a single prompt.

Claude vs ChatGPT — which is better?

Both are excellent. Claude generally produces more natural writing and handles long-context tasks better, while ChatGPT offers stronger multimodal features (image generation, voice) and a larger ecosystem of custom GPTs.
