What is Cosine?
Cosine understands your codebase better than you do. 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.
We’re not just simply an LLM wrapper. We’ve had to build a search engine, vector database, static analysis (LSP), and fine tune multiple LLMs to get to something that is context aware, can answer complex questions and is useful day to day.

Hello, Cosine seems to be a great tool. If it's understands the whole code base, can it generate doumentation and package/classes/methods... descriptions, etc?

Hey PH community! Super super pumped to have guys try Cosine out. If you need some inspiration as to what prompt you should use. Here are some cool ones.
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 , how do I do that?

I've been an early beta tester for Cosine and I can tell it's incredibly useful to teams with large codebases and helping engineers right better code.
Kudo to the team for the incredible work so far!
