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.
Our team has been hard at work since we were last here. We hit general release with Cosine, our AI software engineering agent, back in May 2025. Now, after lots of improvements, we re back with one of our largest feature updates yet!
I don t want to spoil too much about what we re coming out with on Thursday 11th, but I think it s going to be a game-changer for how devs ship from their workflow.
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.
Buildt is an AI tool giving you a ChatGPT like experience in your codebase. Helping developers quickly search and understand large codebases. It’s like having a colleague with perfect memory and understanding of your codebase sitting next to you.
