Cosine is an artificial intelligence software engineering company providing an autonomous coding agent for development teams. Its platform connects to codebases and workflow tools such as GitHub, Jira, Linear and Slack, enabling teams to assign tickets as they would to an engineer. Cosine can investigate repositories, plan changes, fix bugs, build features, refactor code, run tests and submit pull requests for review. The business serves the software development and enterprise technology industry, with particular relevance for organisations managing large, complex or regulated codebases that need faster delivery without replacing human engineering oversight.
