Cursor Composer
Multi-file edit feature in Cursor — describe a change in natural language, agent updates files across the project. Launched 2024.
Iterates with Cursor's tab-autocomplete and inline edits. Powered by GPT-4o, Claude 3.5/4, Gemini, or local models. Differs from Copilot Chat: project-aware, multi-file diffs you accept/reject one at a time. Agent mode (2025) takes it further — runs a long-running task autonomously. Competitors: Windsurf (Cascade), GitHub Copilot Workspace, Cline (VS Code extension).
