cdai – the AI-enhanced cd command

cdai is a smart shell navigation tool that lets you jump to any directory, even ones you've never visited, by indexing configured roots and combining frecency ranking with fuzzy matching. It handles natural-language intent like 'latest' or 'oldest' without AI, and optionally uses a local or cloud LLM to re-rank existing paths — never invent new ones. Tab completion is fully deterministic and model-free.
