Claude
Japanese Claude（クロード）
Claude is a conversational AI assistant made by Anthropic in the US that writes answers, text and code when you ask it. One name covers several models and plans, so check which Claude you use and with what settings.
Claude is an AI assistant you talk to by typing. In the web, desktop or phone app you can ask it questions, have it draft emails or summaries, or have it create files. Models with different strengths, such as Opus, Sonnet and Haiku, all sit under the same Claude name, a bit like one shop with several menus. There is a free plan, and paid plans give you more usage and more features.
Watch out Anthropic says that on its personal plans, your chats are used to improve its models if you allow it. Before using Claude for work, check this item in the privacy settings, and keep customer names and contact details out. Prices and features change often, so check the official pricing page again.
