Cosine AI

Developers spend an enormous slice of their week not on the interesting parts of coding, but on reading tickets, tracking down context, writing boilerplate, and manually testing small changes — all the glue work that slows real shipping down. Cosine AI is an AI developer platform that gives engineers tools to automate those software development workflows, so the team spends more time on the hard, fun problems.

At its heart is Genie 2, an autonomous software engineer trained to reason like a human — capable of finding context, making code changes, testing, and committing changes on its own. Genie integrates with the tools you already live in, including Jira, Linear, and Slack, allowing for autonomous task execution and real-time collaborative coding. That means a ticket can go from assignment to draft PR without a human ever having to hand-hold the boring middle steps.
