What is Cosine CLI?
Cosine CLI is a local command-line interface that brings Cosine, our
autonomous AI engineer, directly into your development environment.
Just like pairing with a top engineer, Cosine can chat, plan, code, and refactor directly inside your project. Whether you're solving complex bugs or building features, Cosine works with you, or for you, right from your terminal.

No More Context Switching
Browser-based AI tools break developer flow by forcing context switches into review mode. Cosine CLI keeps you in the zone by bringing Cosine directly into your terminal, right alongside your editor and tools. So you can refactor, test, and build in one seamless session.
Full Local Tool Access
Unlike sandboxed browser solutions, Cosine CLI runs in your actual environment. Cosine can access your local files, run builds, execute tests, and interact with project-specific tools making it a true part of your workflow, not just a disconnected assistant.
Respects Developer Preference
Cosine CLI fits into your existing setup with zero disruption. Developers can invoke Cosine from the terminal without switching editors or learning new tools making adoption effortless and AI assistance feel like a natural extension of everyday coding.
Your Tools. Your Files. Your Flow.

The workflow this enables relative to other local only one-task-at-a-time CLI products actually enables the core promise of agents: massively parallelised workflows which is something that hasn’t been easily done locally - until now.
