Cursor took VS Code's open-source codebase and rebuilt the AI experience around it. Tab autocomplete uses Cursor's own model; Chat and Composer use Claude, GPT, or other model selections you choose; Agent mode plans and executes multi-file changes through a chat interface. By 2026, most professional developers doing meaningful AI-assisted coding have switched from VS Code + Copilot to Cursor. Pricing is $20/month Pro for unlimited basic; premium model usage costs extra. The trade-off vs Copilot: Cursor has better context awareness and agent capabilities; Copilot has tighter enterprise integration and lower friction for VS Code purists.
