Chat with your codebase using AI. Semantic Sync indexes your project files and lets you ask questions about your code from a VS Code sidebar — powered by an Elastic AI agent with semantic search.
Features
AI chat sidebar — Ask questions about your codebase in natural language
Semantic search — The agent retrieves the most relevant files to answer your question, with source citations
Automatic sync — Files are re-indexed on save so your index stays current
Multi-project support — Index multiple repos and filter chat by project
Usage tracking — See how many tokens and files you've indexed

Click the Semantic Sync icon in the Activity Bar
Sign in with GitHub
