Cursor is an AI coding agent platform built to help developers turn ideas into working software. The platform lets users hand off engineering tasks to AI agents while staying focused on decisions, review, and product direction. Cursor agents can explore files, search codebases, write code, run tests, process screen recordings, create demos, and summarize completed work. Cloud agents can run autonomously and in parallel, allowing teams to work on multiple tasks across repositories at the same time. Cursor also supports always-on automations that run on schedules or triggers to build, maintain, and fix software. The platform works across the editor, terminal, Slack, GitHub, CLI, cloud agents, and code review workflows. Developers can use Cursor for feature development, bug fixing, refactoring, CI investigation, deployment work, repository search, billing fixes, infrastructure tasks, and UI polish. Cursor gives teams access to frontier models from providers such as OpenAI, Anthropic, Gemini, SpaceXAI, and Cursor. Its autonomy slider supports lightweight targeted edits as well as more independent agentic development. Enterprise capabilities support secure adoption across large engineering organizations, with SOC 2 certification and tools for teams that need scale. By combining autonomous coding agents, parallel execution, multi-model support, editor integration, terminal workflows, Slack collaboration, GitHub review, automations, and enterprise security, Cursor helps teams build enduring software more quickly.
