The Problem

Developers constantly copy commands from LLMs, Stack Overflow, or history but forget what the options mean. Reading man pages breaks flow, and existing tools are shell-specific or require leaving the terminal. This creates friction and risk when running unfamiliar commands.

Potential Solution

A lightweight daemon with cross-shell plugins that detects command tokens and displays contextual tooltips using man pages, community docs, and AI. Provides inline explanations in any terminal, plus team documentation sync for internal CLI tools.

Why Now?

LLMs are generating more CLI commands than ever, increasing the need for instant documentation. The developer tools market has proven willingness to pay for productivity gains (e.g., GitHub Copilot).

Comment on Nudge

Product HuntJul 17, 2026

If you use Claude Code, Gemini CLI, or Codex and often come back to a terminal that has been waiting for input, Nudge is built for that exact moment. Happy to answer questions about how it works.

I have made man pages 10x more useful (zsh-vi-man)

r/programmingNov 29, 2025

If you use zsh with vi mode, you can use it to look for an options description quickly by pressing `Shift-K` while hovering it. Similar to pressing `Shift-K` in Vim to see a function's parameters. I built this because I often reuse commands from other people, from LLMs, or even from my own history, but rarely remember what all the options mean. I hope it helps you too, and I’d love to hear your thoughts.
