Codebase Indexing And Semantic Search Infrastructure

via “codebase semantic indexing and retrieval with embeddings”

Open-source AI code assistant for VS Code/JetBrains — customizable models, context providers, and slash commands.

Unique: Implements a local-first semantic indexing system using embeddings and vector search, with support for both local embedding models (Ollama) and cloud APIs. The system chunks code intelligently (respecting function/class boundaries) and stores embeddings in a local vector database, enabling fast semantic search without sending code to external services.

GitHub Copilot uses keyword-based code search; Continue's semantic indexing finds relevant code based on meaning, not just keywords. Cursor doesn't expose codebase indexing as a configurable feature; Continue allows teams to choose embedding models and storage backends.
