Cursor

Cursor is a code editor built from the ground up around AI capabilities. Forked from VS Code, it retains full compatibility with VS Code extensions while adding deeply integrated AI features that go beyond what plugins can offer. Its standout feature is Composer, which can plan and implement changes across multiple files simultaneously. The editor indexes your entire codebase for context-aware suggestions and can reference documentation, previous conversations, and specific files in its responses. Cursor supports multiple AI models including GPT-4, Claude, and its own fine-tuned models. The Tab completion feature learns from your edits to predict multi-line changes, and the inline editing lets you describe changes in natural language.
