Key Features

Three features that make Cursor special:

Cursor AI Features - Tab, Chat, Composer

1. Tab Autocomplete - Smarter Than Copilot

Cursor Tab goes beyond line-by-line suggestions:

  • Suggests entire blocks - complete functions, not single lines
  • Understands context - knows what other files contain
  • Edits existing code - fixes bugs in existing code, not just adds new
  • Tab to accept, Esc to reject - simple, no workflow change

2. Chat - Ask AI About Your Codebase

Chat understands your entire project:

  • Full codebase understanding - ask 'what does this function do' without copy-paste
  • Reference files - type @filename and AI reads that file before answering
  • Apply directly - generated code applies to file instantly, no copy-paste
  • Choose models - Claude, GPT-4, Gemini available per task

3. Composer - Edit Multiple Files at Once

The most powerful feature:

  • Multi-file editing - 'refactor the entire auth system' and Composer edits all related files
  • Preview diffs - see what will change before applying
  • Undo everything - don't like it? Undo all changes at once
