I've built a command-line tool called semantic-grep for searching free-text English content using natural language queries. Some key features: Uses word2vec embeddings to find semantically similar text Written in Go, using only the standard library Familiar CLI UI Can process data streams piped as input Finds similarity in a sliding window of text It's designed for developers and researchers who need to search large text datasets more intelligently than simple keyword matching. The tool is still in early stages, so I'd appreciate any feedback or feature suggestions. GitHub: https://github.com/arunsupe/semantic-grep
