drift vs semble
drift: Drift is a codebase intelligence tool for AI. It detects patterns and conventions in code, remembers decisions across sessions. It can be used as an MCP server for any IDE or as an offline CLI.; semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.
