I recently joined a new company and used Claude extensively to build my understanding of the large monolithic codebase. Being me, I was also curious to learn about how other parts of the codebase worked that I don t work on. So, I built this tool that doesn t depend on me asking questions to feed my curiosity.Abstractions is an app that indexes your codebase and sends out a weekly newsletter to you and your team about how different functionalities or concepts work.You might already ask Claude to answer your questions about your codebase. This works the same way, but it doesn t wait for you to ask. It understands the code, figures out a topic, and sends out a newsletter every week.It s free for now as it is BYOK (supports Anthropic and OpenAI models) and simple compute is cheap.The tool also doesn t store your actual code; it only stores embeddings and a high-level summary of the code.I m planning to open source this because I wouldn t give a random app on the internet access to my company s codebase, but I only want to spend time on it if it s interesting to people.Would love to know what you think.
