Cosine - Your AI Co-developer Ask complex coding questions, get explanations about features and plan new code just by asking our AI in plain English TLDR: Cosine is an AI knowledge engine that understands your codebase better than you do, currently available in the browser, and as a VS Code extension. It supports 50+ coding languages, allowing developers to ask any question about their codebase, get explanations about any feature and get suggestions about how to write new code. Try it out on an open source repo without installation on our website or install our VS Code extension! We’re not just an LLM wrapper. We’ve had to build a search engine, vector database, static analysis (LSIF), and fine tune multiple LLMs to get to something that is context aware, can answer complex questions and is useful day to day. Here’s what you could ask immediately after install! How does testing work? Which architecture does the consumer app use? How does error propagation work across our backend services? How do we expire authentication tokens? Explain how we implement IP based rate limiting How should I add a new chart element to our main dashboard? How can I change the request timeout on all of our services? How do I implement the useForm hook? Why would I use dependency injection in this language? Find the code which sanitises user sign up input Find the recursive tree looping in the parser Clean up the highlighted code Why are all these classes abstract? I need to add <X>, how do I do that? Our ask Try it out on an open source repo without installation or sign up directly on our website or install our VS Code extension with a few clicks! What next? Level 5 coding autonomy - we’re going to let you assign a ticket to Cosine on Linear and it’ll just do it automatically.
