Cursor is a VS Code fork rebuilt from the ground up around AI-assisted development. Rather than bolting AI onto an existing editor, Cursor deeply integrates multi-file editing, codebase-aware chat, and intelligent autocomplete into the core editing experience. It supports Claude, GPT-4, and its own custom models. The standout feature is Cmd+K editing: select code, describe a change in natural language, and Cursor applies the edit across files with a diff preview. The chat panel understands your entire repository — you can ask it to explain architecture decisions, find bugs, or plan refactors with full project context. Tab completion predicts your next edit based on recent changes, not just the cursor position. Cursor has rapidly gained traction among professional developers who want deeper AI integration than what Copilot offers. Its multi-file editing capabilities and codebase indexing make it particularly effective for larger projects where understanding cross-file dependencies is critical.

What the community says

Cursor is the most-discussed AI code editor on Reddit, with communities in r/cursor_ai, r/programming, and r/webdev consistently treating it as the benchmark for AI coding tools. Users frequently report 1.5-2x productivity gains and praise its multi-file editing and deep codebase awareness over GitHub Copilot. The June 2025 shift from a 500-request model to a credit system — effectively cutting monthly requests significantly — triggered a public apology from the CEO and a wave of users migrating to Windsurf. Stability complaints persist, with reports of crashes and performance degradation after recent updates. Based on community discussions from Reddit and developer review sites over the past 12 months.
