Built for Rapid Exploration
Codanna came from our need for rapid research and exploration with proper context. During R&D, quick POCs, and pair-programming sessions, we needed instant answers about our codebase. LSP servers were too slow for that rapid-fire questioning. Speed for iterative exploration: When you’re in research mode or building a POC, you ask dozens of questions rapidly. Codanna’s <10ms lookups keep up with your thought process. Human+LLM pair programming: The human stays in control. You can run the same queries the AI runs, pipe results through Unix tools, verify context before the AI acts. The--watch flag means the index updates as you code.
Semantic understanding: Find code by concept - “where’s the retry logic?” - without knowing exact names. Embedding-based search understands what code does from its documentation.
