A semantic grep-style CLI search tool for exploring code and documents in natural language

About

• Brings natural-language semantic search into the terminal to make up for the limits of traditional grep; useful for exploring large codebases
• After indexing a local repository, supports searching code, documents, PDFs, and images with intent-driven questions like “Where is auth configured?”
• mgrep watch continuously watches a git repository and indexes in the background
  • Recognizes .gitignore and automatically excludes unneeded files
• Uses meaning-based search + reranking rather than exact string matching, putting the most relevant results first
• Can run web search alongside local file search with the --web option
  • The --answer option generates a response summarizing the search results
• Designed with integration with coding agents such as Claude Code in mind
  • Cuts agent token usage by reducing unnecessary repeated grep calls
• Keeps grep-like CLI flags to preserve existing users' muscle memory as much as possible
• Uses a cloud store based on Mixedbread Search so search results can be shared across teams and agents
• Still leaves regular expressions, symbol tracing, etc. to grep/ripgrep, positioning itself as a complementary tool specialized for exploration, onboarding, and understanding context
