Cosine CLI - AI pair programming directly in your terminal | Product Hunt
The coding agent built for
Optimised for complex codebases
“Cosine shows what it looks like when AI works like a real-world developer. Genie 2 mirrors how engineers reason through complexity. It’s a foundational leap for software development.

I definitely see Cosine as one of the leading contenders in agentic programming. Most others just can’t do it, and they're cracking the code. The way Cosine has fine-tuned their model is particularly impressive: it ensures that the agent actually behaves well and digests a lot of context, which other providers consistently struggle with.”

Cosine fits perfectly with agile and buddy programming it’s like having an AI partner. Both junior and senior developers picked it up instantly. It’s boosted productivity and become part of our team.
