semble vs overmind
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.; overmind: Overmind is the first open-source event-driven AI agent cognitive architecture that serves as an external brain for Claude Code. It provides permanent memory, multi-window fleet collaboration, and pre-answer self-checking to eliminate hallucinations and rework.
01
TL;DR
Choose semble if…Enhancing AI agents (e.g., Claude Code, Cursor, Codex) with fast and accurate code search capabilities
Choose overmind if…Avoid re-introducing projects across sessions
