Claude

Claude とは？

Claude is an AI assistant made by Anthropic. It handles writing, analysis, research, coding and long-document work through a chat interface on the web, desktop and mobile apps. It is a good fit for people who work with long texts, such as reports, contracts, research papers or codebases, and who care about clear, careful writing. Claude can read large uploaded files, keep related chats and documents together in Projects, and produce standalone outputs like documents, code or small interactive pages in a side panel called Artifacts. Its responses tend to be measured in tone and it often explains its reasoning.
