CIPHER-Local is a powerful tool that creates a local SQLite index of your codebase using Tree-sitter. This index provides structured code intelligence to various AI coding assistants like GitHub Copilot, Cursor, Claude Code, and Claude Desktop. With CIPHER-Local, these tools can perform tasks such as searching symbols, resolving definitions, finding references, and querying dependencies directly from the local workspace without requiring an internet connection or API keys. It supports 13 different programming languages and is open-source under the MIT license.
