Cosine is an AI engineering platform that helps developers hand off complex coding tasks while maintaining control, visibility, and code maintainability. It operates across three surfaces: a desktop app for multi-window workflows, a CLI for terminal-native power users, and a cloud service for parallel agent execution and remote collaboration. Key capabilities include interactive AI sessions, one-shot task prompts, repository analysis, browser automation via Chrome CDP, MCP integration for external tools, and skills management. Cosine can generate comprehensive test suites, iterate on failures until CI passes, and assist throughout the SDLC from scoping to deployment. It offers enterprise deployment options including public cloud, dedicated tenant, and fully air-gapped setups.
