semble vs Pepper
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.; Pepper: Pepper is an MCP server that injects a dylib into iOS Simulator apps via DYLD_INSERT_LIBRARIES, starting a WebSocket server inside the app process to expose over 50 tools for view hierarchy, touch input, network interception, heap inspection, and more. It simplifies giving AI agents full runtime access to iOS apps for testing and automation.
