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.
I’m Yang, co-founder of Cosine (cosine.sh) along with @alistair_pullen. We’re excited to be back on Product Hunt with our Cosine VS Code release!
Over a year ago, we brought Cosine out of the editor and into the cloud. At the time, we were one of the first VS Code extensions that acted as an agent. The choice to step away allowed us to harden our agent for real engineering work – from enterprise controls, deep integrations, and a remote-first workflow that meets teams where they collaborate.
Now, we're back.
💡 What is Cosine VS Code?
Cosine VS Code brings our agentic software engineer right into your editor. Powered by Genie 2, our proprietary model built specifically for complex coding tasks, Cosine completes tasks end-to-end without human supervision.
Using the Cosine CLI as the bridge to the full power of the Cosine platform, we're able to implement advanced tooling that is fast, robust, and customisable to the needs of our model.
Stay in your editor and use familiar workflows. Preview diffs and jump straight to your files. See updates in real time as the VS Code extension auto-connects to our CLI. Build seamlessly, without friction.
🛠️ More than just an extension
The progress from our early VS Code build to now is massive. This new integration brings truly agentic, production-grade coding to where you work.
We’re looking for feedback from devs who maintain large codebases, ship often, pair program, or just those who prefer native workflows.
Impressive approacH: training a proprietary model like Genie 2 specifically for complex, end-to-end coding tasks feels like the right bet. The ability to understand an existing codebase and autonomously plan and ship changes (not just autocomplete) sets Cosine apart from the typical “AI pair programmer” tools. Curious to see how it performs on large-scale repos and whether it can truly handle multi-file reasoning. 🚀
Huge congrats on bringing Cosine back to VS Code! How does Cosine manage code safety or rollback for autonomous changes? @yang_cosine
For me, the best part is being able to preview everything inside the editor. No switching tabs, no confusion
tried the ginie 2-powered agent today and it really understood context within large files. That’s a big plus

Congrats on the VS Code launch. End-to-end PRs and async tickets feel perfect for taming backlogs. The CLI bridge bringing full agent power into the editor is smart. How does Genie 2 handle very large monorepos and long context? Keen to try.
