Local Code Search

Search your codebase using plain English, right inside VS Code — entirely locally. No code is ever sent to the cloud.

Why

Most AI code search tools send your code to a third-party API. This one doesn't. Everything — parsing, embeddings, and search — runs on your own machine, using a custom-built search engine under the hood.

Features

• Semantic search — search by meaning ("how do I set a timeout"), not exact keywords
• Click to jump — results take you straight to the exact function and line
• Fully local — your code never leaves your computer
• Fast — powered by a custom-built approximate nearest-neighbor index, benchmarked at ~2x faster than brute-force search with 100% recall on real codebases (see benchmarks)

Setup

1. Install the local-code-search core engine (Python)
2. In VS Code settings, search "Local Code Search" and set:
   • Python Path → path to your Python (or venv) executable
   • Main Script Path → path to the core engine's src/main.py

Usage

1. Open the Command Palette (Ctrl+Shift+P)
2. Run "Local Code Search: Index Workspace" (only needed once per codebase, or after major changes)
3. Run "Local Code Search: Search Codebase" and type your question in plain English
4. Click a result to jump straight to that code
