Cosine AI

Onboarding to a complex codebase, tracking down an obscure bug, or executing a repetitive refactor — these are the tasks that eat up your day when you'd rather be building. Cosine AI's Genie is an AI software engineer designed to handle all of it. Genie understands your entire codebase deeply, supports over 50 coding languages, and can explain any part of your code, suggest improvements, and execute tasks autonomously from start to finish. It integrates smoothly into your existing workflows, collaborates in real time, and delivers instant feedback so you're never blocked. Whether you're a solo developer or part of a large engineering team, Genie gives you the kind of expert support that used to require hiring another senior engineer.
