Discover what Cosine AI is and learn how to use it effectively in 2025. We'll explore its key features and see how it stacks up against other tools in the software development space.

Cosine AI is designed to give you a truly superhuman grasp of code. It achieves this by using semantic indexing, building codebase graphs, creating embeddings, and employing a custom model thatâs been trained on actual developer tasks. Itâs much more than just a simple wrapper model; Cosine AI offers a deep understanding of your code and can effectively mimic your teamâs unique coding style.
Buildt is the company behind Cosine AI, and it was developed by Varun Deshpande. Buildt focuses on creating technology like Cosine, which provides superhuman code understanding. They achieve this through advanced semantic indexing and clever heuristic techniques. Essentially, Buildtâs main goal is to build models like Cosine that really boost developersâ productivity and make the coding experience smoother.
Buildt offers some really powerful features for understanding code, including semantic indexing and heuristic search methods like codebase graphs and embeddings. To get the most out of Buildt, hereâs a simple guide:
Ctrl + D.Ctrl + â/â.Ctrl + â/â.â, â, â, â keys.Enter to open a selected entry in a new tab. If you want to open it in a new tab and keep the current one open, use â§ + Enter. You can also expand or collapse lists by using â§ + â/â./.Esc to exit the search focus.+.?. Itâs got more tips on how to use Buildt really efficiently.By following these steps, youâll be able to make the most of Buildtâs advanced code understanding features for all your development projects.
