Navi is an interactive cheatsheet tool for the command line, written in Rust. The problem it solves is simple: you know a command exists but can't remember the exact syntax. Instead of googling or digging through documentation, you type "navi" in your terminal and get a searchable, interactive menu of commands you can run directly. You can browse cheatsheets by category, pick a command, and navi will prompt you to fill in any arguments, showing suggested values from your system dynamically. For example, a git cheatsheet might list "Change branch" and then show you your actual local branches as options, so you never have to remember or type them manually. Cheatsheets are written in plain text files with a simple format. You can write your own, download ones shared by the community, or import them from git repositories. Navi also works with third-party cheatsheet sources. It can be used as a standalone command, as a keyboard shortcut widget inside your shell (similar to how Ctrl-R searches command history), or even inside Tmux sessions (a tool for running multiple terminal windows at once). You would reach for navi when you frequently forget command-line syntax, want to stop copy-pasting from Stack Overflow, or want to build a personal library of shortcuts for tasks you do regularly. It is built in Rust and installable via common package managers.
