Cosine Swarm is AI software engineering at scale, built for long-horizon work and engineers with taste. By transforming objectives into an organized team of specialized agents – Orchestrators, Task Owners, and Workers – it handles complex refactors and system-wide migrations without losing focus. Cosine operates as one runtime across CLI, Desktop, and Cloud. Use Swarm mode for parallel execution for research, implementation, and QA. Return to isolated, human-reviewable PRs.

Cosine CLI brings our AI coding agent to your terminal. It writes/refactors/tests code, runs shell, understands your repo, and continues browser tasks. Autonomous or interactive. Full access to familiar local tools. Meeting developers where they work.

Cosine for VS Code brings our AI coding agent to your editor. It writes/refactors/tests code, and executes multi-step edits. Using our CLI as the bridge, build with the full power of our agentic workflow. A disciplined teammate that works where you code.

Cosine understands your codebase better than you do. It supports 50+ coding languages, allowing developers to ask any question about their codebase, get explanations about any feature and get suggestions about how to write new code.
