# Claude Claude is a [[Large Language Models (LLMs)]] created by [[Anthropic]]. There are multiple variants of Claude: - Haiku - Sonnet - Opus Those evolve over time. Currently (June 2025), Claude 4 Opus is the most powerful model, closely followed by Claude 4 Opus. I personally consider it as superior to [[GPT4]] (all variants) and [[Gemini]]. There's a free and a different paid tiers. ## Projects Claude Projects enable creating a stable "context" for conversations with Claude. Within the context of a project, Claude will already know what you have discussed before. It's useful when working on a project, to avoid having to repeat the same information over and over (e.g., project goals, scope, current status, previously discussed ideas, etc). On a Claude Project page, it's possible to configure the "Project" knowledge, that is, the starting context for all discussions. The Project knowledge can be defined using: - Custom instructions (i.e., a prompt) - Content (e.g., documents, text, images, etc) ## Styles Claude supports selecting different output styles. Some are built in, but it's also possible to create custom styles. Here's an introduction to this feature:  ## Computer Use See [[Claude Computer use]]. ## Desktop ### Introduction Anthropic provides an official desktop client for Claude. Since November 2024, Claude Desktop has become MUCH more powerful, because it can be integrated with arbitrary data sources through Anthropic's new open standard called [[Model Context Protocol (MCP)]]. ### Feature previews Click on your name in the bottom left corner, then select "Feature Preview" to view and enable feature previews. ### Integrate with Google Drive Claude can access data stored in Google Drive. To connect your account, click on your name in the bottom left corner, then choose "Settings", then click on "Connect" in the "Connected accounts" section. After connecting your account, a Google Drive icon will appear below the chat box, allowing you to load recent Google Drive files, or files by URL. ### Configuration - On Windows, the configuration is located in `%appdata%/Claude` - On MacOS, it is under `~/Library/Application Support/Claude` For configuring MCP, please look at [[Model Context Protocol (MCP)]]. ## Code Claude also has a CLI called [[Claude Code]]. ## Model Context Protocol (MCP) Support Claude Desktop has deep support for [[Model Context Protocol (MCP)]] servers. It acts as an MCP client, but also supports [[Desktop Extensions for MCP]], enabling easy installation of local MCP servers: ![[Claude - DesktopExts Support.png]] ## References - Official Website: https://claude.ai/ - Claude Downloads: https://claude.ai/download - Anthropic's Website: https://www.anthropic.com/ - Claude Projects: https://www.anthropic.com/news/projects - Claude Styles: https://www.anthropic.com/news/styles A comparison of Custom [[ChatGPT]] GPTs and Claude Projects:
