Main ways to access Claude

Claude is available through four main interfaces, each optimized for a specific type of task. The first is Claude dot ai, along with the associated mobile and desktop apps. This is the main way of interacting for most people: questions and answers, brainstorming, creating and editing documents, analyzing files. This very interface is the focus of this course. The second is Claude Code. This is an agentic developer tool that can directly edit files on your computer, execute terminal commands, and create git commits. The third is Claude's integration with Slack. It lets you talk to Claude directly inside your workspace: through mentions in threads or through a dedicated AI assistant section. Claude can search for context in your Slack channels, direct messages, and files. The fourth is Claude for Excel. This is a side panel in Microsoft Excel, where Claude can read, analyze, modify, and create new spreadsheets directly in your working file.
