I built a small Bash helper called brain that turns natural language into shell commands directly in your prompt.

You type what you want to do, press a shortcut, and the command appears in-place (not executed). Think of it like !!, but for intent instead of history.

Example:

show git config username

→ press Ctrl+G →

git config user.name

You can edit it or hit Enter — nothing runs automatically.

Why I built it I often know what I want to do in the shell, but not the exact flags or syntax. I wanted something faster than searching docs, and safer than auto-executing AI output.

Design choices

Bash-only (no zsh magic)

Uses a standalone script + readline integration

Does NOT auto-execute commands

Python stdlib only (no dependencies)

Happy to hear feedback, edge cases, or suggestions.
