What is Cosine?

Cosine is an agentic AI tool for software engineering that can be installed on‑premise or within a VPC, supporting fully air‑gapped deployments. It connects to GitHub, Jira, Slack, Linear, Trello, Asana, and other project tools to launch and manage multiple coding tasks in parallel.

Cosine drafts pull requests, writes tests, scans for bugs, and performs large‑scale refactors, while maintaining control for the developer to review and approve changes. The system offers a “research mode” for rapid analysis of legacy or third‑party repositories and can be fine‑tuned on proprietary codebases, including legacy languages.

Security and compliance features include SOC 2 attestation, ISO 27001 alignment, audit logs, role‑based access control, encryption at rest and in transit, and no data leakage from the environment. Users can control data retention policies, access management through their identity provider, and real‑time monitoring of usage anomalies.
