We are on a mission to make every developer 10x more productive through AI-powered development tools.
Cosine Loop was born from frustration. As developers at leading tech companies, we spent countless hours navigating large codebases, trying to understand legacy code, and waiting for code reviews.
We knew AI could help, but existing tools were often too simplistic or compromised on privacy. So we built what we wished existed: an AI assistant that truly understands code, respects privacy, and integrates seamlessly into developer workflows.
Today, over 50,000 developers and hundreds of companies trust Cosine Loop to accelerate their development. We’re just getting started.
To empower developers worldwide with AI tools that amplify their capabilities while respecting their code and privacy.
