Hash

Hash is a POSIX shell that integrates AI as a first-class feature without forcing you to a single vendor. Type ?? anywhere in a command to get help from Claude Code, Cursor CLI, Gemini CLI, Ollama, or other ACP agents. Features include turn-by-turn conversations with agents, local learning from your command patterns, and a context picker that lets you control exactly what information leaves your machine.

Built for developers who want AI assistance in their shell workflow while maintaining privacy and flexibility. Hash learns from your error-fixing habits, auto-detects git context, masks sensitive environment variables, and lets you review every payload before sending it to an agent. The maker indicates it was built with Claude Code.
