Can you vibe code an entire search engine? This ex-Googler tried.
Former Google engineer Hugh Williams successfully built a functional search engine using Anthropic's Claude Code without writing manual code. He emphasizes that while AI is powerful, it functions best as a tool for experienced engineers who act as 'coaches' rather than replacements.
Why it matters
It provides a practical case study on the evolving role of software engineers in an era of AI-assisted development.

After previously showing how Anthropic's coding assistant helped him build an AWS-based system in 48 hours , Williams has been using Claude Code recently to create a working search engine called Zettair that indexes 1.5 million Wikipedia articles. The project includes features you'd expect from a modern search engine: autosuggest, query-biased snippets, related searches, trending topics, and AI-generated summaries. Williams says he wrote zero lines of code himself, relying entirely on Claude Code. That's technically true, with an important caveat: the underlying search engine is based on an information-retrieval system he helped build in the early 2000s. His biggest takeaway wasn't that AI can replace engineers. Instead, Williams argues Claude Code works best when paired with deep technical expertise. Building with AI, he says, feels less like programming and more like coaching — and experienced engineers still make the best coaches. Sign up for BI's Tech Memo newsletter here .
