Cursor AI

AI coding agent

Cursor is where the best founders build products people want, fast. Accelerate your development with hundreds of agents, ship full products autonomously, and use the best model for every task.

Cursor is a coding agent built for speed. Describe a feature, a bug fix, or a refactor. Cursor explores your repo, writes the code, runs tests, and hands you a diff to review. What used to take an afternoon can take minutes.

Tab keeps you moving during inline work with predictions across files. Cloud agents run in parallel on isolated machines so multiple tasks advance at once. Bugbot flags issues in code review before they slow down your next deploy.

YC companies, Stripe, and NVIDIA use Cursor to shorten development cycles. During Bugbot's beta, it reviewed over 1M PRs and surfaced over 1.5M issues. More than 50% were resolved before merge.

Key features

• Frontier models on demand — Composer 2.5, GPT-5.5, Opus 4.8, and others. Pick the fastest model for the task at hand.
• IDE, terminal, and Slack — Same agent everywhere you work. No context rebuild when you switch surfaces.
• MCPs, skills, and hooks — Wire in your stack and cut the setup time on every repeated workflow.
• Bugbot — Catch issues in code review before they turn into rework and slow the next release.
• Tab for constant velocity — A dedicated Tab model predicts multi-line edits across files so you rarely break flow.
• Parallel cloud agents — Run multiple agents at once on isolated machines. Your roadmap does not have to wait in a single queue.
