## About VibeAtlas
**VibeAtlas** is the reliability infrastructure for AI coding. We help developers:
- 🎯 **Reduce AI token costs** by 40-60% through intelligent context optimization
- πŸ” **Improve code search accuracy** with semantic understanding
- πŸ›‘οΈ **Add governance guardrails** to AI-assisted workflows
### This Demo
This demo showcases our semantic code search powered by
[UniXcoder](https://huggingface.co/microsoft/unixcoder-base), a code-specific
embedding model from Microsoft Research.
**Key Features:**
- Natural language β†’ code search
- Cross-language pattern matching (Python, JavaScript, TypeScript)
- Semantic similarity (understands code intent, not just keywords)
### Try It In Your IDE
Get the full experience with our VS Code extension:
```bash
code --install-extension vibeatlas.vibeatlas
```
