I wanted a tool that could research any topic deeply — not just one web search, but Wikipedia, arXiv, Semantic Scholar, GitHub, Hacker News, Stack Overflow, Reddit, YouTube and local documents, all at once. So I built it. This post covers the architecture decisions, the parallel execution model, the self-correction loop, and a few things that didn't work before I got it right.
